Patients with combined mitral valve operation and coronary artery surgery represent a high risk group. The aim of this retrospective study was to evaluate which factors affect early and late postoperative results in this particular group of considered high risk patients. PATIENTS AND METHOD. Between 1984 and 1997, 264 patients (mean age: 63 +/- 7.3 years) underwent mitral valve surgery (199 patients; 75% mitral valve replacement, 25% mitral valve repair) in combination with coronary revascularization (mean 2.4 +/- 1.3 grafts). Follow-up comprised a mean of 69 +/- 42 months and was 98.3% complete.Early mortality was 10.6% (28/264). Ischemic mitral regurgitation operated on in emergent status, moderate to severe reduced left ventricular function and advanced age (60 years) were independently associated with early hospital mortality (p0.05). Ischemic etiology of mitral valve disease (emergency and elective operations), severity of mitral regurgitation and New York Heart Association (NYHA) functional class IV were related to early hospital mortality, only with univariate statistics. Actuarial survival was 86, 69 and 48% at 1, 5 and 10 years, respectively. The preoperative NYHA functional class was the only variable independently related to late survival. Eighty-five percent of the surviving patients were in NYHA functional class I and II.Mitral valve operation combined with coronary artery bypass grafting is associated with a high early hospital mortality. Independent risk factors of early mortality are emergency operation of ischemic mitral valve disease, reduced left ventricular function and advanced age. Long term survival is independently influenced only by preoperative NYHA functional class IV. |
