Clinical risk model for predicting 1-year mortality after transcatheter aortic valve replacement.

ABSTRACT:

Objectives

Estimating 1-year life expectancy is an essential factor when evaluating appropriate indicators for transcatheter aortic valve replacement (TAVR).

Background

It is clinically useful in developing a reliable risk model for predicting 1-year mortality after TAVR.

Methods

We evaluated 2,588 patients who underwent TAVR using data from the Optimized CathEter vAlvular iNtervention (OCEAN) Japanese multicenter registry from October 2013 to May 2017. The 1-year clinical follow-up was achieved by 99.5% of the entire population (n = 2,575). Patients were randomly divided into two cohorts: the derivation cohort (n = 1,931, 75% of the study population) and the validation cohort (n = 644). Considerable clinical variables including individual patient's comorbidities and
