Asymptomatic Regional Thinning of Left Ventricle After Mitral Valve Replacement.

ABSTRACT

We report the successful repair of a rare case of regional thinning of the left ventricle after mitral valve replacement. An 80-year-old woman underwent prosthetic mitral valve replacement for mitral valve stenosis. Her postoperative course was uneventful; however, regional thinning of the left ventricular wall was detected on transthoracic echocardiography on postoperative day 7. We repaired the thinned area with a patch by using the felt sandwich technique. Postoperative echocardiography and computed tomography showed a successfully repaired left ventricular wall.
