Repair of left ventricular aneurysm in the setting of noncompaction.

Although left ventricular (LV) aneurysm is a well-described complication of ischemic heart disease, it may less frequently develop in the setting of normal coronary anatomy and myocardial blood supply. LV noncompaction (LVNC) is a particularly rare etiology of LV aneurysm; in the few cases previously reported in the literature, non-surgical management was pursued. In this report, we discuss the surgical repair of an 'idiopathic' LV aneurysm in a patient who presented with multiple thromboembolic events, with LVNC as the likely etiology on the underlying LV pathology. <Learning objective: Left ventricular (LV) noncompaction represents a rare etiology of LV aneurysm; although non-surgical management of this condition has been previously reported, we demonstrate that early surgical intervention is an acceptable treatment option.>.
