Project description:Left ventricular (LV) thrombus formation is a frequent complication in patients with acute anterior myocardial infarction (MI). Its incidence is lower with inferior wall MI. Risk factors for the development of LV thrombus are consistently irrespective of infarct treatment and include large infarct size, severe apical akinesia or dyskinesia LV aneurysm, and anterior MI.
Project description:Rheumatic heart disease is the most common valvular heart disease in developing countries. Recurrent syncope due to a large, free-floating left atrial thrombus is a rare presentation of rheumatic mitral stenosis. We report this uncommon finding on echocardiogram in an elderly woman presenting to the emergency department with giddiness for the past few months.
Project description:Left ventricular apical thrombus is a known complication following an anterior ST-elevation myocardial infarction. Although left ventriculography may suggest an apical thrombus in the presence of a filling defect, additional imaging with echocardiography and/or cardiac magnetic resonance is strongly recommended to further characterize the thrombus post myocardial infarction.
Project description:Male patient in dilated phase of hypertrophic cardiomyopathy had multiple hospitalizations during the past 2 years either due to congestive heart failure, stroke, scar epilepsy, or atrial fibrillation and ventricular tachycardia. Medication included evidence based therapy for heart failure, cordarone and warfarin. Anticoagulation had to be discontinued due to marked fluctuations in INR. Transthoracic Echocardiography (TTE) revealed a mobile mass in the left ventricle. He was treated with Dabigatran 110mg twice a day for 4 months without any bleeding or embolic episode and complete resolution of thrombus. Dabigatran is a reversible direct thrombin inhibitor and currently approved for the prevention of thromboembolic episodes in non-valvar atrial fibrillation. This case demonstrates possible thrombolytic properties of dabigatran in resolution of left ventricular thrombus.
Project description:BackgroundInfective endocarditis (IE) predominantly involves the cardiac valves. Timely diagnosis and initiation of therapy significantly reduce morbidity and mortality. Infective endocarditis presenting as a large left ventricular outflow tract (LVOT) mass is an atypical manifestation that provides significant challenges to the treating team.Case summaryA 19-year-young male presented with exertional shortness of breath, palpitations, and presyncope for 4 months with constitutional symptoms for the last 6 months. Two-dimensional echocardiogram showed a large LVOT mass arising from the mitral aortic intervalvular fibrosa causing dynamic severe aortic valve obstruction, moderate aortic regurgitation, and severe mitral regurgitation. He was managed on lines of IE and received intravenous antibiotics. In view of worsening heart failure and cardiogenic shock, he underwent mass excision, mechanical aortic valve replacement, and mitral valve repair. Histopathology confirmed it as vegetation. He was discharged and is doing well at 2-month follow-up.DiscussionAn atypical presentation of IE as a large LVOT mass was observed in this young male. Sound clinical judgement, judicious use of ancillary imaging, and a multidisciplinary approach ensured timely diagnosis and appropriate treatment. Management included appropriate intravenous antibiotics followed by surgery.
Project description:A 4-year-old child with supramitral membrane (SMM) causing severe mitral stenosis (MS) was taken for excision of the membrane. Intraoperative transesophageal echocardiography showed a large thrombus in the left atrial appendage (LAA) in addition to SMM. The case underscores the importance of this extremely rare association and prompt therapy to prevent catastrophic consequences.
Project description:The presence of a left ventricular (LV) thrombus is considered an absolute contraindication to transcatheter aortic valve implantation (TAVI) because of the very high embolic risk. We report a case of TAVI under complete protection of the cerebral arteries in a patient with a large LV thrombus, severely impaired LV function, and no surgical options. (Level of Difficulty: Beginner.).
Project description:Patient with embolic episode should always be evaluated for cardiac mass. Mass in left ventricular can be a myxoma or thrombus even in a normal functioning heart. In either case, mobile mass with embolic potential should be surgically resected.
