Abstract

Purpose: To assess the short and long-term benefits of patients who were submitted to isolated aortic valve replacement or valve replacement (VR) concomitant myocardial revascularization (MR); to evaluate the incidence of postoperative complications, hospital mortality and late mortality.

Methods: From January 1985, through December 1989, 20 consecutive patients underwent surgical intervention, 15 male (75%) and 5 female (25%), the mean age was 74.8% (ranging from 70 to 86 years old), and the aortic valve gradient ranged between 78 and 180 mmHg (mean = 97 mmHg). They presented preoperative diagnosis to have either isolated aortic stenosis (AS) or As and coronary artery disease (CAD). No patient was in NYHA functional class I; 3 patients (15%) were in class II, 14 (70%) in class III and 3 (15%) in class IV.

Results: The most frequent post-operative complications found were: extended intubation in 7 patients (35%), bleeding in 4 (20%), acute renal failure in 3 (15%) and ventricular arrhythmia in 3 (15%). Hospital mortality occurred in 2 patients (10%) who had been submitted to VR and concomitant MR. Late mortality occurred in 1 patient (5%). Through December 1989, 11 patients (64%) were in functional class I (NYHA), 3 (18%) in class II, 3 (18%) in class III and none in class IV.

Conclusion: We concluded that the surgical treatment is indicate to elderly patients with isolated AS os with AS and concomitant CAD. There was a significant post-operative improvement of the functional class (NYHA) to the surviving patients.
