Figure 1: Posterior and apical displacement of posterior-medial papillary muscle typically seen with infero-lateral akinesia or dykinesia at the base of the left ventricular. It causes tethering of posterior mitral leaflet leading to coaptation defect and posterior directed mitral regurgitation jet
