Case of Left Ventricular Pseudoaneurysm After Mitral Valve Replacement

Pseudoaneurysm of the left ventricle, as an uncommon complication after mitral valve replacement, needs early surgical repair because of a high prevalance of rupture. Five years after mitral valve replacement, an aneurysmal mass with narrow orifice was determined at the posterolateral wall of the mitral annulus. Cardiac assessment was performed w ith echocardiography, magnetic resonance imaging and cardiac catheterization. The aneurysmal mass was resected by endocardial approach and the defect was closed with primary suture. Pathologic diagnosis was false aneurysm.
