Early outcome of mitral valve reconstruction in patients with end-stage cardiomyopathy

摘要: Abstract Uncontrollable severe mitral regurgitation is a frequent complication of end-stage cardiomyopathy, significantly contributing to heart failure in these patients, and predicts poor survival. Although elimination valve could be most beneficial this group, corrective surgery has not been routinely undertaken very ill patients because the presumed prohibitive operative mortality. We studied early outcome reconstruction 16 consecutive with cardiomyopathy severe, refractory operated on between June 1993 April 1994. There were 11 men five women, aged 44 78 years (64 ± 8 years) left ventricular ejection fractions 9% 25% (16% 5%). Preoperatively all New York Heart Association class IV, had (graded 0 4+ according color flow Doppler transesophageal echocardiography) two listed for transplantation. Operatively, flexible annuloplasty ring was implanted patients. Four also single coronary bypass grafting incidental disease. In four operation performed through right thoracotomy prior grafting, underwent tricuspid regurgitation. No patient required support an intraaortic balloon pump. no or hospital deaths mean stay 10 days. three late at 2, 6, 7 months after reconstruction, 1-year actuarial survival 75%. At follow-up months, remaining are I II, postoperative fraction 10%. have hospitalizations congestive failure, decrease medications noted. For regurgitation, as opposed replacement can accomplished low longer term mandatory, may allow new strategies yielding improvement symptomatic status (J T HORAC C ARDIOVASC S URG 1995;109:676-83)
