Predictors and risk calculator of early unplanned hospital readmission following contemporary self-expanding transcatheter aortic valve replacement from the STS/ACC TVT Registry

Abstract:

Background Predictors of hospital readmissions and tools to predict readmissions after TAVR are scarce. Our objective was to identify predictors of early hospital readmission following TAVR in contemporary clinical practice and develop a risk calculator. Methods Patients with a contemporary self-expanding TAVR between 2015 and 2017 in the STS/ACC/TVT Registry™ database were included. Patients were divided into a derivation and validation cohort (2:1). A risk score was calculated using the derivation cohort based on multivariable predictors of 30-day unplanned readmissions and applied to the validation cohort. Results A total of 10,345 TAVR patients at 350 centers were included. Unplanned 30-day hospital readmission was 9.2%. Patients with an early readmission had higher 30-day rates for mortality (2.3% vs. 0.8%, p ≪ 0.001), stroke (4.1% vs. 2.7% p = 0.009), major vascular complications (2.0% vs. 1 …
