[Left Ventricular Thrombectomy in Patients with Dilated Cardiomyopathy Accompanied by Cerebral Embolism:Report of Two Cases].

ABSTRACT

Left ventricular thrombus( LVT) formation is a known complication of ischemic heart diseases including acute myocardial infarction, dilated cardiomyopathy (DCM) and myocarditis. Among them, few cases involve DCM. Two DCM patients with LVT developed acute cerebral infarction and underwent thrombectomy. Both patients presented with sinus rhythm and neither had previous thromboembolic event. However, their transthoracic echocardiography (TTE) showed left ventricular ejection fractions<35% and left ventricular diastolic diameters≥60 mm, indicating high possibilities of LVT formation. The TTE findings suggest that DCM patients require anticoagulation therapy and frequent imaging examination, even with sinus rhythm and no history of thromboembolic events. Once a thromboembolic event occurs, thrombectomy is urgently needed.
