title: Patch repair of a giant left ventricular pseudoaneurysm after mitral valve replacement.
abstract: Left ventricular pseudoaneurysm (LVP) is a rare cardiac disorder. We describe the repair of a large LVP that was identified in a 73-year-old woman 10 months after she underwent mitral valve replacement for infective endocarditis at another hospital 10 months previously. Follow-up echocardiography showed an enlarged large mass beside the left ventricle, and computed tomography revealed a LVP and an orifice just beside the mitral annulus. We removed the implanted valve and closed the large orifice (35×4 mm) using a Xenomedica (Baxter Healthcare Corp, Horw, Switzerland) patch. Computed tomography 3 months later revealed a thrombosed LVP.
