Chronic ischemic mitral regurgitation is traditionally a complex lesion to repair. Only restrictive annuloplasty has become an accepted strategy to avoid valve replacement, but results are unsatisfactory in some subgroups of patients. We describe an original technique that addresses the pathophysiologic mechanisms responsible for one of the most common subtypes of ischemic mitral regurgitation, ie, asymmetric tethering of the mitral leaflets after inferior myocardial infarction. The technique includes partial detachment of the posterior leaflet from the mitral annulus, annular plication, and posterior cusp plasty.
