The ECG demonstrated sinus rhythm, and echocardiography revealed a massive left ventricular false aneurysm located in the inferolateral wall, with reduced ventricular function (EF of 32%), LVED of 175 ml, and moderate mitral regurgitation (Figure 1).
Images of chest computed tomography; (A) frontal view, (B) sagittal view, (C) axial view, (D) 3D volume rendering confirm the diagnosis of giant left ventricular pseudoaneurysm

A chest computer tomography (CT) with intravenous contrast demonstrated a large (8.6 x 6.8 cm) narrow-necked aneurysm arising from the base of the inferior and lateral walls of the left ventricle (Figure 2).

The aneurysmectomy was performed using the Dor technique with endoventricular circular patchplasty, simultaneously with cardiac bypass surgery (CABG) and mitral valve annuloplasty (Figure 3).
