Isolated thrombus-producing right ventricular outflow tract obstruction: an unusual presentation of primary antiphospholipid antibody syndrome. Indian Heart Journal. 2005 Nov-Dec; 57(6): 744-6http://imsear.searo.who.int/handle/123456789/4858Right ventricular outflow tract obstruction secondary to an isolated organized thrombus is a rare entity. Proper diagnosis of this condition is essential for the survival of such patients. We describe the case of a middle aged woman who presented with dyspnea and decreased effort tolerance, and was managed with surgical excision of a firm mass which was identified as organized thrombus.engAdultAntiphospholipid Syndrome --diagnosisBiopsy, NeedleCardiac Surgical Procedures --methodsDiagnosis, DifferentialEchocardiography, TransesophagealFemaleFollow-Up StudiesHumansImmunohistochemistryRisk AssessmentThrombectomy --methodsThrombosis --diagnosisTreatment OutcomeVentricular Outflow Obstruction --diagnosisCase Reports
