简介
Background
Transcatheter aortic valve replacement (TAVR)–related coronary artery obstruction prediction remains unsatisfactory despite high mortality and novel preventive therapies.
Objectives
This study sought to develop a predictive model for TAVR-related coronary obstruction in native aortic stenosis.
Methods
Preprocedure computed tomography and fluoroscopy images of patients in whom TAVR caused coronary artery obstruction were collected. Central laboratories made measurements, which were compared with unobstructed patients from a single-center database. A multivariate model was developed and validated against a 1:1 propensity-matched subselection of the unobstructed cohort.
Results
Sixty patients with angiographically confirmed coronary obstruction and 1,381 without obstruction were included. In-hospital death was higher in the obstruction cohort (26.7% vs 0.7%; P < 0.001). Annular …
