Abstract

In this case report, we discuss the critical interdependence of structure and function in demonstrating systolic anterior motion (SAM) of the mitral valve after repeat heart transplantation, where residual apical tissue of the explanted heart remained in place. The resulting conformational changes led to anterior displacement of the mitral valve and persistent SAM.
