    Introduction: European system for cardiac operative risk evaluation (EuroSCORE) is a valuable tool in control of the quality of cardiac surgery. However, the validity of the risk score for the individual patient may be questioned. The present study was carried out to investigate whether the continued fall in short‑term mortality reflects an actual improvement in late mortality, and subsequently, to investigate EuroSCORE as predictor of 1‑year mortality. Methods: A population‑based cohort study of 25,602 patients from a 12‑year period from three public university hospitals undergoing coronary artery bypass grafting (CABG) or valve surgery. Analysis was carried out based on EuroSCORE, age and co‑morbidity factors (residual EuroSCORE). Results: During the period the average age increased from 65.1 ± 10.0 years to 68.9 ± 10.7 years (P < 0.001, one‑way ANOVA), and the number of females increased from 26.0% to 28.2% (P = 0.0012, Chi‑square test). The total EuroSCORE increased from 4.67 to 5.68 while the residual EuroSCORE decreased from 2.64 to 1.83. Thirty‑day mortality decreased from 4.07% in 1999–2000 to 2.44% in 2011–2012 (P = 0.0056; Chi‑square test), while 1‑year mortality was unchanged (6.50% in 1999–2000 vs. 6.25% in 2011–2012 [P = 0.8086; Chi‑square test]). Discussion: The study demonstrates that both co‑morbidity and age has a great impact on 30‑day mortality. However, with time the impact of co‑morbidity seems less. Thus, age is more important than co‑morbidity in late mortality. The various developments in short and long‑term mortality are not readily explained. Conclusion: Although 30‑day mortality of CABG and valve surgery patients has decreased during the 12‑year period, the 1‑year mortality remains the same.

    Abnormal mitral valve apparatus in a case of hypertrophic obstructive cardiomyopathy: Intraoperative transesophageal echocardiography
    (Wolters Kluwer - Medknow, 2018-07) Aggarwal, Neelam; Khanuja, Jasbir Singh; Arora, Sameer Saurabh; Maria, Rahul
    Hypertrophic obstructive cardiomyopathy is a relatively common disorder that signifies asymmetric hypertrophy of interventricular septum causing obstruction of the left ventricular outflow tract (LVOT). However, more recent studies have shown that during ventricular systole, flow against an abnormal mitral valve apparatus results in drag forces on the part of the leaflets. The mitral leaflet is pushed into the LVOT to obstruct it. We present a case where intraoperative transesophageal echocardiography played a crucial role in defining the etiology of LVOT obstruction that subsequently helped in deciding the surgical plan.

    Absent right superior vena cava and persistent left superior vena cava in a patient with bicuspid aortic valve with aortic stenosis
    (Wolters Kluwer - Medknow, 2018-04) Gupta, Kushant; Bhuvana, Vijayakanth; Bansal, Varun; Ray, Ruma; Kumar, Arkalgud Sampath
    Persistent left superior vena cava (LSVC) with absent right SVC (RSVC) is a rare congenital anomaly. If undetected, the condition may pose difficulties in central venous catheter insertion, pacemaker electrode insertion, and cannulation during cardiopulmonary bypass. We describe a case of persistent LSVC with absent RSVC, who was diagnosed to have bicuspid aortic valve with aortic stenosis.

    Absent superior vena cava in tetralogy of fallot
    (Wolters Kluwer - Medknow, 2018-04) Shah, Tejas R; Hiremath, Channabasavaraj S; Diwakar, Anitha; Rema, Krishna Manohar Soman
    Absent superior vena cava (SVC) is an asymptomatic congenital systemic venous anomaly which is rarely detected and compatible with normal life. Undiagnosed absent SVC may cause problems during cardiac catheterization or cardiac surgery. We present our surgical experience in a patient with tetralogy of Fallot who had undiagnosed absent SVC.

    Accidental arterial puncture during right internal jugular vein cannulation in cardiac surgical patients.
    (2016-10) Maddali, Madan Mohan; Venkitaramanan, Arun; Al-Ajmi, Ahmed Wala; Al-Bahrani, Maher Jaffer; Cheskey, Manoj Jayatilaka; Arora, Ram Nishant
    Background: The primary aim of this study was to compare the incidence of accidental arterial puncture during right internal jugular vein (RIJV) cannulation with and without ultrasound guidance (USG). The secondary end points were to assess if USG improves the chances of successful first pass cannulation and if BMI has an impact on incidence of arterial puncture and the number of attempts that are to be made for successful cannulation. Settings and Design: Prospective observational study performed at a single tertiary cardiac care center. Material and methods: 255 consecutive adult and pediatric cardiac surgical patients were included. In Group I (n = 124) USG was used for the right internal jugular vein cannulation and in Group II (n = 81) it was not used. There were 135 adult patients and 70 pediatric patients. Statistical analysis: Demographic and categorical data were analyzed using Student ‘t’ test and chi- square test was used for qualitative variables. Results: The overall incidence of accidental arterial puncture in the entire study population was significantly higher when ultrasound guidance was not used (P < 0.001). In subgroup analysis, incidence of arterial puncture was significant in both adult (P = 0.03) and pediatric patients (P < 0.001) without USG. First attempt cannulation was more often possible in pediatric patients under USG (P = 0.03). In adult patients USG did not improve first attempt cannulation except in underweight patients. Conclusions: USG helped in the avoidance of inadvertent arterial puncture during RIJV cannulation and simultaneously improved the chances of first attempt cannulation in pediatric and in underweight adult cardiac surgical patients.

    Active Paradoxical and Pulmonary Emboli in a First Trimester Pregnancy
    (Wolters Kluwer - Medknow, 2022-12) Nicholas, Suraci; Shifman, Monica; Kumar, Annadita; HaskeNicholasx, Michael; Shifman, Monica; Kumar, Annadita; Haske, Michael
    Capturing a paradoxical embolism in real?time has been a challenge in recent literature. We present the unique case of a 33?year?old, G3P2 female at 8 weeks gestation presenting with dyspnea. An active thrombus through an undiagnosed patent foramen ovale was found requiring emergent surgical intervention with a positive outcome. The presence of a deep vein thrombosis, inferior vena caval thrombus, patent foramen ovale, and pulmonary artery thrombi was contemporarily documented. To our knowledge, there is minimal literature with this presentation.

    Acute Acquired Immune Thrombocytopenia After Cardiac Surgery: A Challenging Case
    (Wolters Kluwer - Medknow, 2023-03) Auci, Elisabetta; Vetrugno, Luigi; Riccardi, Ilaria; Vendramin, Igor; Livi, Ugolino; Bassi, Flavio; Bove, Tiziana
    Thrombocytopenia is a common condition that recognizes an infinite number of possible causes, especially in specific settings like the one covered in this case report: the postoperative period of cardiac surgery. We report a case of an old male with multiple comorbidities who underwent a coronary angioplasty procedure and aortic valve replacement. He showed severe thrombocytopenia in the postoperative days. Differential diagnosis required a big effort, also for the experts in the field. Our goal was to aggressively treat the patient with prednisolone, platelets, and intravenous immunoglobulins to maximize the prognosis. Our patient developed no complications and was discharged successfully

    Acute hemodynamic effects of inhaled nitroglycerine, intravenous nitroglycerine, and their combination with intravenous dobutamine in patients with secondary pulmonary hypertension.
    (2010-05) Mandal, Banashree; Kapoor, Poonam Malhotra; Chowdhury, Ujjwal; Kiran, Usha; Choudhury, Minati
    Objectives: The presence of pulmonary artery hypertension (PAH) affects the prognosis of patients; therefore, it is important to treat it. The aim of this study is to compare the acute hemodynamic effects of inhaled nitroglycerine (iNTG), intravenous nitroglycerine (IV NTG) alone and their combination with intravenous dobutamine (IV DOB) during the early postoperative period, in patients with PAH undergoing mitral valve or double valve replacement surgery. Materials and Methods: In the study, 40 patients with secondary PAH were administered iNTG 2.5 μg/kg/min, IV NTG 2.5 μg/kg/min, a combination of iNTG 2.5 μg/kg/min + IV DOB 10 μg/kg/min, and IV NTG 2.5 μg/kg/min + IV DOB 10 μg/kg/min for 10 minutes each following valve replacement surgery, in random order. The hemodynamic parameters were recorded before (T0) and immediately after the intervention. (T1). Results: iNTG effectively decreased mean pulmonary arterial pressure (mPAP), pulmonary vascular resistance index (PVRI), and the PVR / SVR ratio, without affecting arterial pressures, systemic vascular resistance or mixed venous oxygen saturation (SvO 2 ). IV NTG produced both systemic and pulmonary vasodilation along with a significant fall in SvO 2 . The combination of iNTG and IV DOB caused a significant decrease in mPAP and PVRI, with no significant change in SVRI, PVR / SVR ratio, and SvO 2 . A combination of IV NTG + IV DOB caused both pulmonary and systemic vasodilatation with a significant decrease in SvO 2 . None of the drugs caused any significant change in the cardiac index. Conclusion: All drugs were of similar efficacy in reducing the pulmonary vascular resistance index. Only iNTG produced selective pulmonary vasodilatation, while IV NTG and its combination with IV dobutamine had a significant concomitant systemic vasodilatory effect.
