BACKGROUND: We aimed to determine the influence of preoperative, intraoperative, and postoperative variables on short and midterm results in patients undergoing triple-valve surgery. METHODS: Between September 1989 and December 2003, 157 patients underwent triple-valve surgery with mechanical prosthetic valves. Preoperative, operative, and postoperative data were retrospectively analyzed and risk factors affecting hospital mortality and short and midterm survival were evaluated. RESULTS: The hospital mortality was 2.5%. Multivariate analysis revealed that New York Heart Association functional class IV, low left ventricular ejection fraction (< 0.35) and increased left ventricular end diastolic diameter (> 50 mm Hg) were associated with increased short and midterm mortality. The freedom rate from reoperation and thromboembolic complications at 5 years were 93% +/- 4% and 81% +/- 7%, respectively. In echocardiographic assessments, significant decrease in left ventricular end-diastolic and end-systolic diameters (53.1 +/- 8.3 vs 50.1 +/- 7.1, p = 0.002 and 35.3 +/- 7.4 vs 32.6 +/- 7.2, p = 0.002) was observed. CONCLUSIONS: Triple-valve surgery offers satisfactory short and midterm results and prevents ventricular dilatation. Mortality significantly decreases if surgery is performed before left ventricle functions deteriorate.
