Transthoracic echocardiography detected left ventricular thrombus in 8.85% of patients with abnormal findings, most often due to dilated cardiomyopathy (39.29%) and myocardial infarction (29.76%).

Dilated cardiomyopathy and myocardial infarction are the most common aetiologies of left ventricular thrombus among patients undergoing echocardiography at this center.
Objectives. We sought to determine the prevalence and aetiology of LVT among patients undergoing echocardiography. Methods. We reviewed case notes and echocardiographic data of patient diagnosed with LVT using noncontrast transthoracic echocardiography. Definition of various conditions was made using standard guidelines. Mean ± SD were derived for continuous variables and comparison was made using Student's t-test. Results. Total of 1302 transthoracic echocardiograms were performed out of which 949 adult echocardiograms were considered eligible. Mean age of all subjects with abnormal echocardiograms was 44.73 (16.73) years. Abnormalities associated with LVT were observed in 782/949 (82.40%) subjects among whom 84/782 (8.85%) had LVT. The highest prevalence of 39.29% (33/84) was observed in patients with dilated cardiomyopathy, followed by myocardial infarction with a prevalence of 29.76% (25/84). Peripartum cardiomyopathy accounted for 18/84 (21.43%) cases with some having multiple thrombi, whereas hypertensive heart disease was responsible for 6/84 (7.14%) cases. The lowest prevalence of 2.38% (2/84) was observed in those with rheumatic heart disease. Left ventricular EF of <35% was recorded in 55/84 (65.48%). Conclusions. Left ventricular thrombus is common among patients undergoing echo, with dilated cardiomyopathy being the most common underlying aetiology followed by myocardial infarction. Multiple LVTs were documented in peripartum cardiomyopathy.
Talle et al. (Wed,) conducted a observational in Left Ventricular Thrombus (n=949). Noncontrast transthoracic echocardiography was evaluated on Prevalence and aetiology of left ventricular thrombus. Transthoracic echocardiography detected left ventricular thrombus in 8.85% of patients with abnormal findings, most often due to dilated cardiomyopathy (39.29%) and myocardial infarction (29.76%).
