LONG-TERM OUTCOME OF AORTIC-STENOSIS OPER ATED AT AN ADVANCED-STAGE

From January 1972 to June 1990, 112, patients (39 to 83 years old), 67 males and 45 females were submitted to surgery for sever calcified ao rtic stenosis. 68 patients were in NYHA III (60.72%) and 44 in NYHA IV . Early mortality included 8 patients (7.14%). 6 died for cardiac reas ons. Late mortality was 27.67%. Actuarial survival rate (including pos toperative mortality) was 88.39%, 77.67%. 67.55% and 65.17% at one yea r, five, ten and fifteen years, respectively. Results were significant ly correlated to left branch block on preoperative EKG, episodes of co molete heart failure, significant coronary stenosis, the cardioplegia technique and the association with coronary bypass.
