Abstract:
Between March 1979 and December 1998, 38 patients with isolated chronic aortic insufficiency underwent aortic valve replacement. The aim of this study is to determine whether preoperative echocardiography parameters are useful in predicting operative results in patients with aortic valve replacement for chronic aortic insufficiency. The global survival is 92% in one year and 89% in ten years. We conclude that on end systolic left ventricle diameter < 55 mm has good prognosis (p = 0.019) and there is a strong correlation between preoperative end systolic and post operative end systolic diameter an end diastolic left ventricular diameter > 70 mm and a left ventricular fractional shortening < 25% weren't predictive of a poor prognosis.
