Mitral valve replacement and endocavitary patch repair for a giant left ventricular pseudoaneurysm

Abstract

We present a case of a giant inferior left ventricular (LV) wall pseudoaneurysm. The patient had New York Heart Association class IV heart failure due to severe mitral valve regurgitation and poor LV function. Our operative approach included right thoracotomy, excision of the mitral valve, and patch repair of the pseudoaneurysm neck from inside of the dilated LV cavity followed by mitral valve replacement. Surgery was performed without aortic cross-clamping on a normothermic perfused beating heart. The patient had an uncomplicated cardiac recovery and is doing well 15 months after surgery.
