[Long-term development of aortic valve stenosis surgically treated 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 aortic 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 reasons. Late mortality was 27.67%. Actuarial survival rate (including postoperative mortality) was 88.39%, 77.67%, 67.85% and 65.17% at one year, five, ten and fifteen years, respectively. Results were significantly correlated to left branch block on preoperative EKG, episodes of complete heart failure, significant coronary stenosis, the cardioplegia technique and the association with coronary bypass.
