Mitral valve reconstruction versus replacement for degenerative or ischemic mitral regurgitation

摘要: Abstract Between January 1985 and June 1992 263 consecutive patients had mitral valve reconstruction (133 patients) or replacement (130 for degenerative Ischemic regurgitation. The two groups were similar in sex, age, prior infarctions cardiac operations, hypertension, angina, functional class. Both mean ejection fraction, pulmonary artery pressure, index, incidence of coronary disease. More than ischemic etiology (22 [16%] versus 12 [9%]; p = not significant), fewer ruptured anterior leaflet chordae (9[7%] 39[30%]; significant). Hospital death occurred 4 (3%) 15 (12%) ( 0.02). Late valve-related 3 (2%) 8 (6%) 0.08). Six-year actuarial freedom from thromboembolism was 92% the group 85% 0.12). Freedom all morbidity mortality 73% 0.03). Significant multivariate predictors hospital replacement, class, congestive heart failure, no posterior chordal rupture, nonelective operation. Mitral reconstruction, when technically feasible, is procedure choice regurgitation because significantly lower late events.
