Mitral valve repair for ischemic mitral incompetence

摘要: Ischemic mitral incompetence (IMI) is the most frequent mechanism of regurgitation today and will continue to be so in future, particularly developed countries where rheumatic valve disease has been nearly eradicated. It a complex multifactorial entity related coronary artery that complication myocardial infarction associated with poor prognosis. involves global regional left ventricular remodeling as well dysfunction distortion (MV), including chordae, annulus, leaflets. Mitral IMI characterized by restrictive leaflet mobility due dyskinesia or even akinesia wall which bears one both papillary muscles, thus, extending distance between leaflets, either or, frequently, predominantly posterior leaflet. The muscle its supporting posterior–inferior ventricle are frequently affected.
