Resumen:
Background: The number of nonagenarian patients with aortic stenosis will likely increase due to the ageing population. We assessed the clinical characteristics, management, and outcomes of nonagenarian patients with severe aortic stenosis.
Methods: A total of 177 (117 females and 60 males) consecutive nonagenarian patients from two large contemporary registries were included in this study. Clinical characteristics, comorbidity as assessed by the Charlson Index, clinical management, and outcomes were recorded. The main outcome measure was one-year mortality.
Results: The mean patient age was 91.1 years, and 56 patients (31.6%) had a Charlson Index <3. A strong association between comorbidity and one-year overall mortality was observed, with higher one-year mortality in patients with Charlson Index ≥3 (66.4% vs. 32.1%, p < 0.001). A total of 150 patients (84.7%) were managed conservatively, and 27 (15.3%) underwent transcatheter aortic valve implantation (TAVI). Predictors of a conservative management were treatment out of TAVI centres, lower mean aortic gradient and better functional class. Clinical management was not significantly different with different degrees of comorbidity. A trend toward...
