Predictors of Bleeding after Percutaneous Coronary Intervention
(Sciencedomain International, 2023-07) Esa, K. S. A; Abdelhayi, I. K; Barbary, Y. E; Salama, M. M.
Background: Acute coronary syndrome patient outcomes have been improved using early invasive techniques. The aim of this study was to investigate the incidence, location, and severity of bleeding in PCI-treated cases to identify patient risk profiles and increased bleeding occurrences. Methods: This prospective observational study evaluated percutaneous coronary angiography in 80 patients with hypertension and diabetes mellitus who planned to undergo primary or elective PCI. The cases were separated into 2 groups; those who reported bleeding (n=11) and those who did not (n=69). All patients underwent physical examination, laboratory evaluation, 12-lead electrocardiography, and PCI. Results: In univariate regression analysis, age (OR: 1.09, 95% CI: 1.009 – 1.192), female gender (OR: 4.32, 95% CI: 1.157 – 16.131), history of peripheral arterial disease (OR: 7.31, 95% CI: 1.585 – 33.742), and femoral site of vascular access (OR: 9.6, 95% CI: 2.263 – 40.721) were independent predictors of major bleeding after PCI. In multivariate regression analysis, age (OR: 1.12, 95% CI:1.014 – 1.269), female gender (OR: 13.75, 95% CI: 1.983 – 161.2), history of peripheral arterial disease (OR: 43.38, 95% CI: 3.754 - 1042) and femoral site of vascular access (OR: 13.29, 95% CI: 2.233 – 128.5) were independent predictors of major bleeding after PCI. Conclusions: Patients who reported bleeding after PCI had a significantly higher age, prevalence of female sex, serum creatinine, and transfemoral intervention before and after intervention compared to patients who did not report bleeding, while haemoglobin and transradial intervention before and after intervention were significantly lower in the bleeding cases than in the non-bleeding cases.
Impact of Training Programs on Awareness and Practice of Lifestyle Modifications among Hypertensive Patients Attending Outpatient Clinic of the University College Hospital, Ibadan, Nigeria
(Sciencedomain International, 2023-06) Ijioma, C. E; Uwalaka, I. W; Kamanu, C. O; Okeji, I. E; Aminu-Ayinde, O. E; Abali, I. O; Orji, O. J; Omole, O. R; Madumere, C. W. T; Airaodion, A. I.
Aim: This study sought to investigate the impact of training programs on hypertensive patients' awareness and practice of lifestyle modifications in out-patient clinics of the University College Hospital (UCH) Ibadan, Nigeria. Methodology: The study design was a cross-sectional survey conducted at the out-patient clinics of the University College Hospital (UCH), Ibadan, Nigeria. This setting was chosen due to the accessibility of hypertensive patients receiving regular care and follow-up. The sample size comprised 274 hypertensive patients attending the out-patient clinics for regular hypertension management. A simple random sampling method was employed to select study participants, ensuring a fair representation of the target population. A structured questionnaire was used to collect data from the participants and results were analysed using SPSS. Results: Findings indicate that the training programs greatly increased awareness of hypertension and lifestyle factors affecting hypertension for most participants (74.42%), with all participants recommending the programs. A significant majority of participants (95.74%) reported being on hypertension medication, while nearly all (99.22%) had received some form of training or counselling on lifestyle modification for hypertension management. Notably, all participants reported having made lifestyle changes following the training programs, with the majority rating the effectiveness of the programs as highly effective (57.36%). Further analysis indicated a statistically significant relationship between the effectiveness of the training programs and the participants' age, sex, educational level, and occupation. The most frequent lifestyle modification post-training was dietary changes, with 54.65% of participants reporting that they always engage in a healthy diet for hypertension management. However, the frequency of engagement in other lifestyle modifications, such as regular physical activity and weight management, was not as high. The majority of participants reported significant improvements in hypertension symptoms following the lifestyle modifications. Conclusion: These findings demonstrate that targeted training programs can significantly enhance hypertensive patients' awareness and practice of beneficial lifestyle modifications, thus improving health outcomes. Further, the study underscores the need for such training programs to be tailored according to the age, sex, educational level, and occupation of the patients to maximize their impact.
Blood Pressure Values in Apparently Healthy Sudanese Population
(Sciencedomain International, 2023-06) Hago, E. Y; Bashir, A. A; Abdalla, I. M; Taha, E. E; Mohamed, A. H; Awad, K; Abeadalla, A. A; Ali, I. A; Musa, O. A.
Introduction: Blood pressure is one of the most often measured clinical parameters, and assessment of blood pressure has a considerable impact on diagnostic decisions. Objectives: To establish blood pressure normal reference values in Sudanese. Methods: A cross-sectional study was conducted from September 2016 to November 2018. Eight hundred eighty-eight healthy adult Sudanese between the ages of 18 and 60 (203 men and 685 women) were randomly selected from the states of Khartoum, Northern, Gezira, Red Sea, and North Darfur. Clinical, anthropometric, and blood pressure measurement data were collected. Results: The mean for all volunteers was 113.93 ± 9.917 mmHg, systolic blood pressure (SBP) and 75.29 ± 6.79 mmHg, diastolic blood pressure (DBP). SBP in men was 118.6 + 7.642 mmHg compared to 112.53 + 9.121 mmHg in women, while DBP in men was 77.51 + 5.984 mmHg compared to 74.63 + 6.844 mmHg in women. Beside the gender variations, blood pressure values also showed geographical variability. There was a positive connection between blood pressures (SBP and DBP), BMI, and age. (P < 0.05) was used for significance. Conclusion: Blood pressure of Sudanese was found to be within the normal international range with gender and geographical variability. It showed positive correlation with age and BMI.
Multi-vessel Disease Percutaneous Coronary Intervention versus Coronary Artery Bypass Grafting in Patients with Chronic Kidney Disease
(Sciencedomain International, 2023-02) El Amrawy, A. M; Hassan Abdelnabi, M; Almaghraby, A
Background: Revascularization of the coronary arteries is associated with better short term and long term prognosis in patients having multivessel coronary artery disease (MV-CAD) and chronic kidney disease (CKD). However, whether revascularization using coronary artery bypass grafting (CABG) surgery or percutaneous coronary intervention (PCI) using drug eluting stents (DES) is better remains unknown. Objectives: To compare the outcomes of revascularization by multi-vessel PCI using DES versus revascularization by CABG in patients with CKD having multivessel CAD, regarding in-hospital and one-year major adverse cardiovascular and cerebrovascular events (MACCE). Methods: This was a retrospective analysis of the data of a group of patients having CKD with eGFR less than 60 ml/min with multivessel CAD who underwent revascularization by PCI or revascularization by CABG and were compared as regards in-hospital and one-year MAACE. Results: A total of 565 patients were reviewed in this study, 230 patients had multivessel PCI using DES while 335 patients had CABG. Comparing both revascularization groups regarding in-hospital MACCE, patients who had mutli-vessel PCI had significantly lower in-hospital mortality, cerebrovascular events (stroke/TIA) and lower total MACCE than patients who had CABG (P-value = 0.03 & 0.01 & 0.04 respectively). When comparing both revascularization groups regarding one-year MACCE, patients who had mutli-vessel PCI had significantly lower cerebrovascular events and total MACCE than those patients who had CABG (P-value = 0.02 & 0.03 respectively). Conclusion: This is a retrospective study to determine which strategy is better for revascularization of CKD patients having multivessel CAD; we can conclude that multi-vessel PCI using DES for CKD patients and multivessel CAD had advantages over CABG regarding in-hospital and one-year cerebrovascular accidents (TIA/stroke) and regarding total MACCE. Larger randomized controlled trials are required to confirm our findings.
Role of P Wave Duration and Tissue Doppler Imaging as Predictive Indicators for Paroxysmal Atrial Fibrillation in Hypertensive Patients
(Sciencedomain International, 2023-02) Osama Awad, M; Elsalam Mostafa, D. A; Naseem, M; Abd Elwahab Hamdy, E.
Background: Atrial fibrillation (AF) is the most prevalent chronic arrhythmia in the heart. AF accounts for one-third of rhythm disorder hospitalizations. AF increases profoundly the risk of stroke, heart failure, and death. This study used P-wave and transthoracic echocardiography with tissue Doppler imaging (TDI) to determine paroxysmal AF predictors in hypertensive individuals. Methods: This case control study was performed on 100 hypertensive adult patients. They were classified into two equal group: Group I included hypertensive patients diagnosed to have paroxysmal AF. Group II (control group) included hypertensive patients with normal sinus rhythm. All subjects were subjected to electrocardiographic and conventional and tissue Doppler Imaging measurements. Results: Pmax had significantly increased in PAF patients compared to sinus rhythm patients. PAL, PAR, PAI, LR, LI and IR had significantly increased in PAF patients compared to sinus rhythm patients. In Multivariate logistic regression analysis, Pmax, PAL, PAI, PAR, LR, LI and IR were found to be independent predictors for PAF. Therefore, Pmax, PAL PAI, PAR, LR, LI and IR were found to be significant predictors for PAF. Best cut-off values for Pmax, PAL, PAI, PAR, LR, LI and IR were: (118, 81, 61, 49.9, 34, 20 and 16 ms) with sensitivity (76, 96, 96, 88, 82, 86 and 77.5 ), specificity (84, 100, 98, 92, 78, 82 and 76) and the AUC of (0.850, 0.979, 0.987, 0.961, 0.836, 0.891 and 0.798) respectively. Conclusions: Electrocardiographic P-wave analysis and echocardiographic TDI may identify hypertension patients at risk for paroxysmal AF, since the combination of Pmax and TDI may help in predicting the development of AF in hypertensive individuals.
Influence of Congenital Heart Defect Types over Cardiopulmonary Bypass, Aortic Cross-Clamping, and Intensive Care Unit Length of Stay and Their Association with Genetic Factors
(Sciencedomain International, 2023-06) Silva, L. L. de M. da; Telles, B. de B; Correia, J. D; Silveira, D. B; Rosa, E. B. da; Nunes, M. R; Cardoso, D. da C; Barcellos, D. H. de C; Zen, P. R. G; Rosa, R. F. M.
Aim: Surgical correction of congenital heart defects (CHD) often requires interruption of blood flow through cardiopulmonary bypass (CPB) and aortic cross-clamping (ACC), for which duration(s) are considered to be prognostic factors, along with intensive care unit (ICU) length of stay (ICULOS). The aim of this study was to evaluate these surgical prognostic factors in pediatric patients with different types of CHD regarding their type of lesion and associated genetic factors. Study Design: Cross-sectional cohort study with 307 pediatric patients. Place and Duration of Study: Pediatric Intensive Care Unit (ICU) of Hospital da Criança Santo Antônio, in Porto Alegre/RS, Brazil, from 2006-2009 (3 years) Methodology: After inclusion criteria, we studied 266 pediatric patients admitted for the first time in a reference cardiac pediatric ICU from Southern Brazil following cardiac surgery. Intraoperative prognostic factors such as duration of CPB, ACC and ICULOS, in addition to dysmorphological and cytogenetic examinations were compiled and analyzed. P-values of <0.05 were considered significant. Results: CPB time was associated to four outflow tract defects (Tetralogy of Fallot [ToF], transposition of the great arteries [TGA], double outlet right ventricle, and truncus arteriosus [TA]), atrioventricular septal defect, and hypoplastic left heart syndrome (HLHS) (P < 0.001). ACC duration was associated with three outflow tract defects (ToF, TGA, and TA) and HLHS (P < 0.001). Moreover, CPB and ACC times showed an association with cyanotic and complex heart defects, as well as prolonged ICULOS (P < 0.001). There was no relationship between these prognostic factors and syndromic aspects or cytogenetic findings. Conclusions: CHD type has an impact over CPB and ACC duration and ICULOS, whereas genetic factors are not associated with those prognostic factors.
Coronary Artery Ectasia as a Predictor of Major Adverse Cardiac Events in Patients with Acute ST Elevation Myocardial Infarction
(Sciencedomain International, 2023-02) Saleh Saad, A; Ahmed Gaafar, A; Salama, M. A. E.-M; Mohamed Abd El-Mageed, R.
Background: Coronary artery ectasia (CAE) is characterised as localised or widespread non-obstructive lesions of the epicardial coronary arteries with a luminal dilation more than 1.5 times the neighbouring normal segments or vessel diameter. Isolated CAE is CAE in the absence of severe coronary artery stenosis. This aberrant dilatation of coronary arteries can produce angina pectoris and even myocardial infarction in people without coronary artery disease owing to vasospasm, dissection, or thrombus. The purpose of this study was to evaluate the connection between CAE and major adverse cardiac events (MACE) following acute myocardial infarction with ST elevation. Methods: This was a prospective cohort study which was carried out on 300 cases. Cases were divided into two groups: Group I: including about 22 STEMI cases with CAE and Group II: including about 278 STEMI cases without CAE. All cases in this study were subjected to full history taking, clinical examination, laboratory tests, standard 12-leads ECG, resting transthoracic echocardiography (TTE), and coronary angiography. Results: Regarding MACE in the studied groups, Incidence of reinfarction and cardiac death were significant higher in cases with STEMI and CAE than cases with STEMI alone. In univariate regression analysis, CAE (OR: 3.59, p value =0.022) was a significant predictor of cardiac death but age, male sex, and EF were not. Also, in multivariate regression analysis CAE (OR: 3.49, p value =0.029) was a significant predictor of cardiac death but age, male sex, and EF were not smoking with high warfarin consumption. Further, Markis classification 1 and 3 were the most frequent phenotype among cases. In STEMI cases, the incidence of reinfarction and cardiac death were significantly higher in cases with STEMI and CAE than cases with STEMI alone. So, CAE is a significant predictor of cardiac death.
Real World Evidence of Bempedoic Acid on Efficacy and Safety in Patients with Uncontrolled LDL-c and at High Risk of CVD
(Sciencedomain International, 2023-06) Manoj, S; Shah, J; Kumar, D; Pradhan, A; Kinare, A. B; Sharma, A. K; Aditya, M. S; Raj, R. A; Raina, A. A; Patel, A; Das, B; Bathe, D. S; Muchhala, S; Jhaveri, K.
Background and Objective: Cardiovascular disease (CVD) is a significant cause of morbidity and mortality worldwide, with high-risk patients requiring effective management to reduce their risk of cardiovascular events. Bempedoic acid is a novel therapeutic agent recently approved as an add-on therapy to statins in patients with uncontrolled LDL-c. Bempedoic acid inhibits cholesterol synthesis in the liver, which ultimately reduces the risk of cardiovascular events. Therefore, the present study aims to assess the efficacy and safety of bempedoic acid in patients with uncontrolled LDL-c (Previously on moderate or high-intensity statins) with a high risk of CVD in real-world settings. Methods: This is a multicenter, retrospective, observational study on the data of high-risk-CVD patients collected from Bempedoic Acid on Efficacy and Safety in patients (BEST) Registry. The clinical data of 140 patients who were already on statin therapy and were receiving Bempedoic acid at a dose of 180 mg, along with measurements of the level of LDL-c, HbA1c, HDL, TG, TC, PPPG, FPG, AST, ALT, serum creatinine was taken into consideration. The primary outcome includes a change in LDL-c level, and secondary outcomes involve a change in the level of HbA1c, HDL, TG, TC, PPPG, FPG, AST, ALT, and serum creatinine at week 12 and 24. Adverse events were reported at both time points. Results: A total of 140 patients were included in the present study with a mean age of 51.8 ± 9.2 years and had primary confirmed diagnosis of dyslipidemia with uncontrolled LDL-c. The mean levels of LDL-c decreased from the mean baseline value of 142.67 ± 46.49 mg/dL, to 106.78 ±33.92 mg/d; a statistically significant reduction by 23.23% (p < 0.01) at week 12. Similarly, at week 24, the mean LDL-c value reduced to 90.39 ± 38.89 mg/dL. A 33.38 % decrease was observed (p < 0.01). Other parameters such as non-HDL, FPG, PPPG, AST and serum creatinine also showed statistically significant reduction at week 12 and week 24. Conclusion: The present study demonstrates that bempedoic acid is an effective add-on medication in lowering LDL-c levels in high-risk CVD patients with uncontrolled LDL-c.
Relationship between Duration of Diabetes Mellitus and Gensini Score in Patients Undergoing Diagnostic Coronary Angiography
(Sciencedomain International, 2023-06) El-Naghy, E. M; Salama, M. M; El-Hefnawy, S. B; Omer, M. A. K. A.
Background: Gensini (G score) is one of the most widely used scoring systems in cardiology. It is an objective method to determine the coronary artery disease severity according to angiographic findings. The aim of this work was to assess the relation between G score and the chronicity of diabetes mellitus (DM) in cases undergoing coronary angiography. Methods: This prospective cohort research was carried out on 300 cases with diabetes mellitus (DM) on antidiabetic treatment who were referred to diagnostic coronary angiography for suspected coronary artery disease. G score was calculated for measurement of the coronary artery disease severity. During the period from October 2020 to Aril 2022 Results: Age, smoking, chronicity of DM, cholesterol, triglycerides test, and electrocardiogram were statistically prominent positively related with G score, while female gender was statistically significant negative relation with it. Also. Mean G score was statistically prominent higher in cases with ischemic changes than in cases without ischemic changes. Therefore, the chronicity of DM was statistically significant predictor of G score. Conclusions: significant positive relation between the G score and the chronicity of DM.

(Sciencedomain International, 2023-05) Tahir, A. F; Zahidi, H. A; Njie, M; Zahri, S; Haboub, M; Arous, S; Bennouna, M. G; Drighil, A; Azzouzi, L; Habbal, R
Hypertrophic cardiomyopathy (HCM) is the most common non-ischemic cardiomyopathy with a prevalence of 1:500 in the general population, based on the recognition of the phenotype. HCM is defined by the presence of increased left ventricular (LV) wall thickness that is not solely explained by abnormal loading conditions and the phenotype also includes disorganized myocyte arrangement, fibrosis, small-vessel disease, and abnormalities of the mitral valve apparatus. In particular to this pathology, we have conducted a one-year prospective study to determine clinical, echocardiographic features and etiopathogenic aspects of hypertrophic cardiomyopathy in the Casablanca university hospital. The results concluded that 50% of the causes was due to amyloidosis 35%, sarcomeric HCM and 15% Fabry disease in which 2 cases were related with pregnancy. Transthoracic echocardiography and cardia MRI plays an important role in HCM diagnosis and prognosis.
Relationship between Aortic Root Diameter and Type 2 Diabetes in Hypertensive Patients
(Sciencedomain International, 2023-02) Elhosary, A. M; Allaithy, A. M; Abd-alaal, M. A; Kassem, H. K.
Background: Diabetes mellitus (DM) involves a series of metabolic conditions associated with hyperglycaemia which is caused by defects in insulin secretion and./or insulin action. The aim of this work was assessment of the relationship between Aortic Root (AOR) diameter and type 2 diabetes mellitus (T2DM) in Hypertension (HTN) cases. Methods: This prospective case control study was carried out on 80 HTN cases. Cases were divided in to three groups: Group A (30 HTN cases) with type 2 DM with good metabolic control (Hb AIC ? 7.0), group B: (30 HTN cases) with type 2 DM with poor metabolic control (Hb AIC > 7.0) and C (Control group) 20 HTN, non-DM subjects of the same age and sex group with no other comorbid conditions. Results: FS had a significant decline in group A (P2 = 0.001) and in group B (P3 <0.001) than C. EF had a significant difference among all groups (P <0.001). Early wave declaration time (DT) had a significant decline in group A (P2 = 0.049) and in group B (P3= 0.023) than C. Tissue doppler early velocity wave had a significant difference among all groups (P = 0.004). Tissue doppler early velocity wave had a significant decline in group A and B than C. (P2 = 0.038. P3 = 0.003). Conclusions: AOR in HTN cases had a significant decline in DM cases compared with non-DM cases. In our results, glycaemic control didn’t play a significant role in aortic root.
Hemoglobin Level as a Predictor of Major Adverse Cardiovascular Events and Short-term Outcomes in Stemi Patient Treated with Pharmacoinvasive Strategy versus Primary PCI
(Sciencedomain International, 2023-02) Abd-el-Sadek Al-Rossasy, A. Z; Mohammad Al-Laithy, A; Hussein El-Barbary, Y; Mohammad Al-Masry, M.
Background: Anaemia is prevalent among cases with acute coronary syndrome (ACS) and has been linked to poor clinical prognosis. Guidelines for cases with ST-segment elevation myocardial infarction (STEMI) recommend timely primary percutaneous coronary intervention (pPCI) as the preferred reperfusion strategy. If timely pPCI cannot be performed, a pharmacoinvasive strategy (PI) is recommended within 12 hours of symptom onset. The aim of this work was to study and assess the impact of hemoglobin level as a predictor of MACE and short-term outcomes in cases treated with Primary PCI vs pharmacoinvasive strategy. Methods: This prospective case-control observational study was conducted on 100 cases that were divided into 2 groups. Group I consisted of 50 anaemic cases & group II consisted of 50 cases that were not anaemic. Both groups were subdivided into A subgroups that underwent revascularization by pPCI and B subgroups that underwent revascularization by pharmacoinvasive strategy. Results: There was no significant difference in LVEF, infarct site and final TIMI flow, the anaemic groups showed statistically significant more total MACE than non-anaemic groups whether revascularized by pPCI or pharmacoinvasive strategy. As expected, anaemic cases tended to have higher bleeding complications especially those undergoing pharmacoinvasive strategy. The anaemic cases also were less likely to be discharged on RAAS and beta blockers. Conclusions: Anaemic cases whether revascularized with pPCI or pharmacoinvasive strategy tend to have higher incidence of MACE and major bleeding with no significant difference in mortality. There was no significant difference between LVEF between the study groups.
Severe Pulmonary Hypertension Secondary to Concomitant Mitral Stenosis with Veno-occlusive Disease in the Context of Systemic Sclerosis: Importance of Careful and Comprehensive Assessment
(Sciencedomain International, 2023-07) Boutgourine, M; Nabawi, H; Maatof, B; El-Jamili, M; El-Karimi, S; Hattaoui, M. E.
Pulmonary Arterial Hypertension (PAH) is a clinical syndrome consisting of physiologic/ hemodynamic criteria that are a consequence of several etiologies. Confirmation of pulmonary hypertension is based on right heart catheterization. Pulmonary hypertension is a devastating condition that can lead to considerable morbidity and premature mortality. In the last few decades, significant advancement in the pharmacotherapy of pulmonary hypertension has resulted from better understanding of the complex pathogenesis and pathophysiology of this dreaded disease. Despite these accomplishments, pharmacotherapy of pulmonary hypertension is still far from perfect, and the mortality in this modern treatment era is still unacceptably high. We report a complex clinical presentation characterized by severe pulmonary hypertension secondary to concomitant mitral stenosis with veno-occlusive disease in the context of systemic sclerosis. Our case highlights the importance of a systematic and comprehensive diagnostic approach to avoid missing an underlying pathology.
Echocardiographic Aspect of Infectious Aortic Endocarditis: Experience of the Cardiology Department, Mohammed VI University Hospital of Marrakech, Morocco
(Sciencedomain International, 2023-05) Onguema, J. R. I; Zerhoudi, R; Othende, F. B. E; Bourzeg, K; Eljamili, M; Karimi, S. E; ElHattaoui, M.
Introduction: Infective Endocarditis (IE) is a serious disease whose prognosis depends on early management. Aortic localization is characterized by its progression to myocardial failure and the high number of complications motivating early recourse to surgery. The diagnosis of AR is based on microbiological and imaging studies. Echocardiography is the recommended imaging modality to make the diagnosis, assess the impact and guide surgery. Materials and Methods: This is a retrospective study, including all subjects over 20 years of age who presented with infective endocarditis of the aortic valve, hospitalized between January 2019 and December 2022, in the Department of Cardiology and Vascular Diseases at the ERRAZI-CHU Mohammed VI Hospital in Marrakech. Clinical, paraclinical and therapeutic data were collected for each case using an exploitation form. Results: During the study period, 26 patients had presented with aortic positional AR, with a sex ratio that was equal to 1.8. The mean age of the patients was 43±12.5 years. A known history of valvular disease was found in 57% of the cases. Among the native valvular diseases, rheumatic origin was found in 85%. The most common valvular lesions were represented by vegetations (88%), which were mobile in 56%, measuring between 10 and 20 mm in half of the cases, their most predominant localization was on the ventricular side with a tilt.IE on severe IAo was found in 90% of cases. The most common associated valvulopathies were MI (53%), RAo (38%) and MR (34%), whose severity was variable. The association of aortic disease with mitral disease was the most frequent association. Echocardiographic complications were presented by fistulas, perforations and peri-aortic abscesses (2 cases each) which were correlated with severe AI. Regarding the impact of the aortic AR on the LV, we noted a marked dilatation in 42% of cases with a preserved ejection fraction in 74%. A quarter of our patients had undergone transesophageal echocardiography in addition to transthoracic echocardiography, with an average time between admission and completion of 3 days. The indication of its realization was posed in front of the doubt of the visualization of an image of vegetations or suspicion of complications not visualized with the TTE. Valvular lesions found on TEE were essentially vegetations in 45% of cases, prolapses in 22% of cases, as well as abscesses, para-prosthetic leaks and prosthesis deinsertion found in 11% of cases. Conclusion: Aortic AR remains a frequent pathology in our context. Aortic insufficiency is the most predisposing valvulopathy and the most common sonographic appearance is vegetations. The results of our study have shown that complications of AE occur preferentially in patients with severe aortic insufficiency.
Takayasu's Arteritis with Aortic Insufficiency as Initial Presentation: A Case Report
(Sciencedomain International, 2023-05) Tahir, A. F; Badaoui, K; Boucetta, A; Abouradi, S; Assklou, A; Haboub, M; Arous, S; Bennouna, M. G; Drighil, A; Azzouzi, L; Habbal, R
Takayasu's disease is the first cause of inflammatory aortitis in young subjects. The disease preferentially affects the women. Takayasu's disease could be a mode of non-specific reaction of the aorta to various infectious or dysimmune etiological factors. Aortic insufficiency is present in 7 to 10% of cases. It is usually moderate. Its mechanism is not unambiguous: direct damage to the aortic valves or dilation of the aortic annulus. Coronary damage responsible for angina or even myocardial infarction are also possible. We report the case of a severe aortic insufficiency secondary to takayasu disease complicated by acute coronary syndrome in a 42-year-old woman.
Management of Bifurcation Culprit Lesion in the Setting of Anterior ST Elevation Myocardial Infarction
(Sciencedomain International, 2023-05) Amrawy, A. M. E; Assal, A. R; Zaki, A. M; Eltahan, S. M.
Introduction: Coronary bifurcation lesions are considered one of the challenging entities in the field of coronary intervention due to the risk of side branch loss and higher risk of stent thrombosis. However, there is limited data about the proper management of such lesions in the setting of myocardial infarction as most bifurcation lesion studies excluded patients with acute coronary syndromes (ACS). The aim of this study was to compare in-hospital and mid-term outcomes of single-stent and two-stents strategy in the management of bifurcation culprit lesions in patients presenting with anterior STEMI. Methods: This retrospective multi-center study included all patients presented with anterior STEMI who underwent primary PCI between January 2017 and December 2019, coronary angiography showed true bifurcation lesion with sizable side branch that can be managed by stenting. Patients with left main bifurcation, those indicated for urgent CABG, and patients in cardiogenic shock were excluded. Included patients were divided into two groups according to the stenting strategy either single or two stents. Six months follow up data were collected by telephone calls and by examination of medical records. Results: Out of 1355 anterior STEMI patients presented between January 2017 and December 2019, 158 patients (11.6%) were identified to have bifurcation culprit lesions with a sizable diagonal branch. 93 patients (59%) were treated by single stent while 65 patients (41%) were managed by two-stents strategy. The baseline characteristics and angiographic findings were similar in both groups except for higher side branch involvement in the two stents group (83.31%±11.20 vs 71.88%±15.05, t= -5.39, p <0.001). Mean fluoroscopy time (23.96±8.90 vs 17.81±5.72 mins) and contrast volume (259.23± 59.45 vs 232.58± 96.18 ml) were significantly higher in two stents group than single stent group (p=0.049). However, the angiographic success rates (residual stenosis ?30% and restoration of TIMI flow grade II or III) were comparable (96.8% vs 99%, MCp=0.151). There is no significant difference in the overall incidence rate of MACE in both groups 6 months following the index procedure (13.9 % vs 16.9%, FEp=0.698), with no difference between different bifurcation stenting techniques in patients managed with two stents. Conclusion: Although two stents strategy in the setting of STEMI is much complex with more fluoroscopy time and contrast volume, the procedural success rate and the incidence of MACE were comparable to one stent strategy, on medium-term follow up.

A coronary fistula is defined as a direct connection between a coronary artery and a heart chamber, great vessel, or other vascular structure that "bypasses" the myocardial capillary bed. This is a rare pathology that is usually not discovered until later in life, and exceptionally not during childhood. We report the case of a young patient who was hospitalized for chest pain and shortness of breath and who was found to have a coronary fistula on angiography. A 66-year-old patient. Hypertension on dual therapy for 16 years and diabetes on OAD (Oral Antidiabetic) for 4 years. He was hospitalized with typical angina pectoris and dyspnea, and the stress test was positive. Laboratory examination revealed a good general condition with NYHA stage 3 dyspneic angina pectoris extending to the upper extremities and no evidence of heart failure. Looking at the balance, we see a slight increase in troponin. ECG returns to regular sinus rhythm, with electrical LVH (left ventricular hypertrophy) and ambient negative waves, no rhythm or conduction abnormalities. Transthoracic echocardiography (TTE) reverses hypertensive heart disease with good global and partial contractility without significant valvular disease associated with systolic pulmonary arterial pressure (SPAP) at 35 mmHg. Coronary angiography is performed and shows evidence of minor involvement of the central CX artery and a coronary camera fistula from the first diagonal artery draining into the left ventricle. Management was about optimizing medical care. The patient received an appointment and was declared discharged. Coronary camera fistulae are rare, found in approximately 0.3% of coronary angiographic studies performed. Most are congenital and may occur primarily due to trauma, erosive infection of the vessel wall, or iatrogenicity during transluminal coronary angioplasty, myocardial biopsy, or valve replacement. In many cases, simple but complex forms can be described. The gold standard for confirming the diagnosis remains coronary angiography, which highlights both the affected arteries and drainage sites. Cardiac scanners occupy an increasingly important position, especially as they provide morphologically accurate information. Surgical or percutaneous treatment of the fistula with a coil is recommended in symptomatic adult patients, especially those with significant or complicated right-to-left shunts. The authors suggest treatment with ?-blockers when multiple sinusoidal fistulas associated with ventricular wall hypertrophy are present. Close monitoring is recommended for asymptomatic small fistula. Corneal fistula is a rare congenital or acquired condition that is mostly asymptomatic and discovered in adulthood. Coronary angiography and heart scan can be used to confirm the diagnosis. Treatment is usually surgical or endovascular. However, in some cases, drug treatment with beta-blockers may help.

Aims: Cardiovascular disease (CVD) is the leading cause of death in dialysis patients as well as in kidney transplant recipients (KTx). Left ventricular hypertrophy (LVH) starts early during the course of chronic kidney disease and is a strong predictor of CVD. We hypothesised that kidney transplant is significantly associated with improvement in cardiovascular reserve. We conducted a prospective study to compare changes in CV before and after kidney transplantation in patients with ESRD who received KTx to control individuals who received PD but did not receive a KTx. Study Design: A Case-Control Study. Place and Duration of Study: Clinic for nephrology Clinical Center University of Sarajevo, Bosnia and Herzegovina. Methodology: In this case-control study, we included 50 KTx from the Kidney Transplant Outpatient Clinic for nephrology Clinical Center. For each 50 KTx, PD outpatients matched for gender and age were recruited. All patients underwent transthoracic echocardiography, and LV (left ventricular) mass (LVM), LV mass index (LVMi), and indices of cardiac function were measured. In the small subgroup of 18 KTx, we retrospectively assessed and compared the LVMI measurements, during dialysis and the post-transplant period. Results: The prevalence of LVH was 24% in KTx patients and 72% in PD patients (NS). KTx had significantly lower LVM, LVMi levels, E/A ratio, FS, and LA diameter compared with the PD group, while the EF and other echocardiographic parameters did not differ. In the subgroup of 18 KTx, LVMi levels after transplantation were significantly lower than dialysis LVMi levels. Conclusion: LVH is the most frequent cardiac abnormality at the time of kidney transplantation. After KTx, the reduction of LVH and diastolic dysfunction was significant. CV remodelling after successful KTx is related to better kidney function, and can explain better outcomes for patients with kidney transplants over patients on long-term dialysis.
Double Outlet Right Ventricle Infective Endocarditis: A Rare Combination and a Therapeutic Challenge
(Sciencedomain International, 2023-05) Elmasrioui, J; Islah, Y; Eljamili, M; Karimi, S. E; Elhattaoui, M; Benfaddoul, O; Idrissi, M. O; Ganouni, N. C. I. E.
Infective endocarditis involving the right side of the heart occurs rarely and often involves the tricuspid valve. The isolated pulmonary valve infective endocarditis (IPVIE) is a less common condition that occurs in specific population. The double outlet right ventricle (DORV) is an unusual congenital heart disease. The association of DORV and IPVIE darkens the prognosis. We report two cases of the association of DORV and IPVIE. The transthoracic echocardiography (TTE) is the base to the diagnosis. Right sided infective endocarditis in the lack of a guided strategy remains a therapeutic challenge.
Pacemaker Infective Endocarditis: Diagnostic and Therapeutic Particularities in 2 Case Reports Including One of the Left Heart
(Sciencedomain International, 2023-06) Seydou, H. I; Noel Maschell, M.-M; Taher, F. A. F; Brahim, N; Meryem, H; Arous, S; Bennouna, E. G; Abdessamad, D; Leila, A; Rachida, H.
Pacemaker infective endocarditis is a more real diagnostic problem than a therapeutic one. The precise impact is not well known. Its incidence is poorly known, and it is a serious infection with an estimated mortality of around 25%. It is with this in mind that we report 2 clinical cases with a literature review. Case 1: An 88-year-old patient with a double chamber pacemaker was admitted for febrile syndrome with a fever at 39.2°. Transthoracic and transesophageal echocardiography (TOE) found an image of vegetation on the aortic valve measuring 9mm, located on the noncoronary cusp, and overflowing on the right coronary cusp. An inflammatory syndrome was found on blood tests. Blood culture, wound swab culture, and bacteriological study of material after removal revealed Staphylococcus Aureus Meti S. The patient was initially put on Vancomycin with a loading dose of 2g / 24h then 1g / 24h, and the pacemaker was extracted. Case 2: A 68-year-old with a double chamber pacemaker (PM) was admitted for fever at 39 ° c with suppuration of the PM pocket. Echocardiography identified an image on the tricuspid valve measuring 14x8 mm evoking vegetation given the context. Two blood cultures and swabs isolated a Staphylococcus aureus. The patient was administered Triaxon 2g / day for 4 weeks and gentamycin 180 mg for 15 days. The pacemaker was removed. Pacemaker Infective endocarditis is rare, poorly understood, very serious, and potentially fatal, accounting for up to about 7% in some case series. In half of the cases, they affect the endocavitary leads, but also the valves, and in 45% of cases the infection of the pocket. The average age is 65 years. The clinical symptoms are disparate making the diagnosis more difficult, it must be evoked in case of unexplained fever in a patient implanted with a Pacemaker. Bactericidal dual therapy should be administered after blood cultures in case of strong suspicion of infective endocarditis (IE) and adapted after identification of the germ in question. Most authors are adamant about extracting any pacemaker whenever possible.
