摘要: Abstract One hundred five patients underwent mitral valve replacement for relief of isolated regurgitation between 1974 and 1979. There were 4 in-hospital deaths (4 percent) 12 late giving an 82 percent predicted 5 year survival rate. An age 60 years or more at the time surgery a preoperative left ventricular ejection fraction less than 0.40 only variables that correlated with decreased 3 to after operation (p 8.6 100 patient years) did porcine (2.8/100 It is concluded that, in addition age, function as measured by predicts undergoing regurgitation. Clinical recovery good even though majority long-term survivors have postoperative decrease fraction.
