Abstract

This report describes a case of systemic thromboembolism caused by left ventricular (LV) thrombosis that developed after placement of an implantable cardioverter-defibrillator (ICD). A 27-year-old male patient was diagnosed with idiopathic dilated cardiomyopathy and ventricular tachycardia, and underwent ICD implantation for the primary prevention of sudden cardiac death. Two weeks after ICD implantation, the patient experienced renal infarction. Transthoracic echocardiography revealed a mobile thrombus at the LV apex, and automated function imaging demonstrated deteriorated LV function after ICD implantation. The RV was not placed by ICD and the mechanical force which was occurred by ICD that led to induced dyssynchronous motion of the LV apex may have resulted in a systemic thromboembolism.
