BackgroundThe impact of frailty status on TAVR outcomes in nonagenarians is unknown. The present study aims to investigate the impact of frailty status on procedural outcomes and overall survival in nonagenarians after TAVR.MethodsA frailty score (FS) was derived by using preoperative grip strength, gait speed, serum albumin, and daily activities. Patients were divided into two groups: Frail (FS ≥ 3/4) and Non-Frail (FS <3/4). Health status was assessed using the 12-item Kansas City Cardiomyopathy Questionnaire (KCCQ). Baseline demographic and clinical characteristics were compared in both groups. The effect of frailty status on outcomes was investigated. Cox regression analyses were performed to determine predictors of overall all-cause mortality. Kaplan-Meier survival curves were used to estimate survival.ResultsSeventy-five patients >90 years underwent full assessment for frailty status. There was a significant improvement in overall health status of non-frail patients (mean difference: 11.03, P = 0.032). Unadjusted 30-day and 2-year mortality rates were higher in the frail group than the non-frail group. (14% vs. 2% P = 0.059; 31% vs. 9% P = 0.018). Kaplan-Meier estimated all-cause mortality to be significantly higher in the frail group (log-rank test; P = 0.042). Frailty status was independently associated with increased mortality (hazard ratio: 1.84, 95% C.I: 1.06-3.17; P = 0.028) after TAVR.ConclusionAmong nonagenarians selected to undergo TAVR for severe aortic stenosis, a considerable number are frail. Nonfrail patients report a significant improvement in overall health status in the short term. Worse frailty is strongly associated with diminished long-term survival. © 2017 Wiley Periodicals, Inc.© 2017 Wiley Periodicals, Inc.
