Descrição: The greater longevity observed today has caused an increase in the number of elderly who need surgery. Aortic stenosis is a common condition in this age group. To evaluate morbidity and mortality in people aged 75 years or older who have undergone valvuloplasty or valve replacement surgery for aortic stenosis alone or associated with other injuries. We studied 230 consecutive cases between Jan/2002-Dec/2007. Patients were 79.5 +/- 3.7 years (75 - 94), and 53.9% were men. In the sample, 68.7% had hypertension, 17.9% had atrial fibrillation, 15.9% were obese, and 14.4% had undergone previous heart surgery. At surgery, 87.4% underwent aortic stent placement, and 12.6% underwent aortic valvuloplasty. The mortality rate was 13.9% (9.4% with isolated aortic stenosis versus 20.9% with an associated procedure, p = 0.023) and the morbidity rate was 30.0% (25.2% with aortic stenosis alone versus 37.4% with an associated procedure, p = 0.068). The most common complications were: low cardiac output (20.2%), renal dysfunction (9.7%), and prolonged ventilatory support (7.9%). In the bivariate analysis, the main predictors of mortality were low cardiac output (RR 10.1, 95% CI: 5.02-20.3), use of intra-aortic balloon (RR 6.6, 95% CI: 3.83-11.4), sepsis (RR 6.77, 95%: 1.66-9.48) and renal dysfunction after surgery (RR 6.21, 95%: 3.47-11.1). As for morbidity, the predictors were: pre-operative renal dysfunction (RR 2.22, 95%: 1.25-3.95), atrial fibrillation (RR 1.74, 95%: 1.16-2.61), and chronic obstructive pulmonary disease (COPD) (RR 1.93, 95%: 1.25-2.97). Aortic valve surgery in the elderly is related to a slightly higher mortality rate than in younger patients, and its main risk factors were associated procedures, renal failure, atrial fibrillation, COPD, and sepsis.
