    Abstract:
    Population over 80 years who require surgery for degenerative aortic stenosis has largely increased in the past decades. We have compared short- and mid-term results for conventional aortic valve replacement (AVR) for calcific-degenerative aortic stenosis in older and younger than 80 years operated at our institution between April 2004 and December 2008. Predictors of mortality and major adverse cardio and cerebrovascular events (MACCEs) on the postoperative and follow-up period were determined through multivariable analysis. Four hundred and fifty-one patients were included in the study. Ninety-four (20.8%) were >or=80. Previous cardiac surgery [odds ratio (OR)=4.08, P=0.047], renal failure (OR=6.75, P<0.001), concomitant coronary artery bypass grafting (CABG) (OR=2.57, P=0.034), female sex (OR=2.49, P=0.047), and severe pulmonary hypertension (OR=3.68, P=0.024) were independent predictors of in-hospital mortality. In the follow-up, age >or=80 years [Hazard ratio (HR)=2.44, P=0.02], high blood pressure (HBP) (HR=5.2, P=0.025) and peripheral arterial disease (PAD) (HR=5.1, P<0.001) were independent predictors for late mortality. Only PAD (HR=3.55, P=0.014) and HBP (HR=8.24, P=0.04) were independent predictors for late cardiac mortality. Renal failure (OR=2.57, P=0.005), severe pulmonary hypertension (OR=3.49, P=0.005) and concomitant CABG (OR=2.49, P=0.002) were independent predictors for postoperative MACCEs. Diabetes mellitus (HR=2.03, P=0.033) and PAD (HR=2.3, P=0.041) were independent predictors for MACCEs in the follow-up. According to these data, we can conclude that conventional open AVR for degenerative aortic stenosis grants good early- and mid-term outcomes in octogenarians in our experience.
