Echocardiographic observations of leaflet motion have taught us volumes about the mechanism of valvular heart disease. Identifying excessive versus restricted mitral leaflet motion, as in Carpentier's classification, has become the foundation of repair techniques tailored to the individual patient.1 Ischemic mitral regurgitation (MR) has nevertheless remained a therapeutic challenge,2–6 with important failure and recurrence rates after standard annular ring reduction,7,8 and a higher peri-operative mortality than with degenerative MR.2–5 In ischemic MR as well, echocardiography has firmly established that restricted leaflet motion is the fundamental mechanism in the vast majority of patients,9,10 confirming the proposal that displacement of the papillary muscles (PMs) in the remodeling heart tethers the leaflets into the ventricular cavity.11–17 Echocardiography has provided further mechanistic clues: the anterior
