A rare case of systolic anterior motion (SAM) after mitral valve repair is described. A temporary postoperative left ventricular (LV) dysfunction protected against this complication during the early postoperative period. Only on day 9 postoperatively did the left ventricle recover and SAM develop, with significant obstruction of the LV outflow tract. Subsequently, mitral valve replacement was required. This case demonstrates the importance of the LV geometrical relationships that predispose to this complication.
