Background and aim of the study: Increased life expectancy has resulted in the elderly frequently presenting with severe aortic stenosis. It has therefore become important to define indications for conventional aortic valve replacement (AVR) and transcatheter aortic valve implantation (TAVI) in this patient population. Thus, patients aged ≥70 years undergoing conventional isolated AVR were evaluated for predictors of early and late mortality. |
≥80 years, operative status, previous intervention, renal failure, and mitral regurgitation. The early non-fatal complication rate was similar for patients aged 70-79 years and ≥80 years, but late mortality was lower between 1998 and 2002 than between 1982 and 1997 in patients aged 70-79 years, and in those aged ≥80 years. The 10-year actuarial survivals after AVR in patients aged 70-74, 75-79, and ≥80 years were 54 ± 3.0%, 43 ± 3.8% and 17 ± 3.9%, respectively. Multivariate predictors of late mortality were age 75-79 years, age ≥80 years, peripheral vascular disease (PVD) and chronic obstructive pulmonary disease (COPD). Female gender was shown to be protective. |
