Ischemic Mitral Regurgitation: Impact of the Left Ventricle and Mitral Valve in Patients with Left Ventricular Systolic Dysfunction

Mitral tenting in combination with regional left ventricular myocardial scarring are important mechanisms to the development of ischemic MR. Surgical annuloplasty addresses mitral tenting, but has little impact on the effect of regional scarring. Moderate-to-severe ischemic MR develops in patients with regional scarring of the anterior-lateral and inferior-posterior regions, and new surgical developments should take this into account.
