Mitral valve repair for ischemic mitral insufficiency

摘要: Abstract Over a 5-year period, 1,292 patients had operation on their native mitral valves. Ischemia was the cause of insufficiency in 84 (6.5%). Sixty-five (77.4%) valve repair. Mean age 66 ± 10 years; 35 (53.8%) were women. degree preoperative 3.2 0.7; mean New York Heart Association functional class 3.3 0.7. Eleven (16.9%) acute and 54 (83.1%) chronic insufficiency. Valve prolapse present 26 (40%). Restrictive leaflet motion secondary to regional or global left ventricular dilatation occurred 39 (60%). All associated myocardial revascularization followed by transatrial valvuloplasty. Multiple techniques employed achieve competence: resection (3), chordal shortening (15), papillary muscle reimplantation (10), annuloplasty (63). There six (9.2%) hospital deaths (acute, 9.1%; chronic, 9.3% [not significant]; prolapse, 11.5%; restrictive, 7.7% significant]). The postoperative 0.6 0.8 51 patients. At follow-up 3.1 1.6 years, patient survival 96% for with 48% those restrictive ( p = 0.02). improved all groups. Ischemic is an uncommon disease that amenable repair majority cases both onset. operative mortality low, superior prolapse.
