Clinical experiences of surgical repair for mitral regurgitation secondary to papillary muscle rupture complicating acute myocardial infarction.

摘要: Mitral regurgitation secondary to ischemic heart disease carries a significant mortality even after emergency open surgery. From 1993 1997, four patients were operated on for mitral papillary muscle rupture. These between 58 and 69 years of age all in class III or IV the New York Heart Association Classification. The responsible infarction area was located lateral wall 2 patients, inferior others. interval onset acute myocardial appearance from 1 10 days. Three had partial rupture (defined as only one several heads ruptured), total Primary plasty performed 3 including patient who undergone patch closure ventricular septal perforation at infarction. combined with coronary artery bypass grafting patient. Only case, rupture, required reoperation recurrence regurgitation. We suggest that case regurgitation, when is partial, repair because its potential improving therapeutic results.
