Why the study?
What are the predictors for permanent pacing after transcatheter aortic valve implantation in high-risk patients with symptomatic aortic stenosis?

TAVI with the CoreValve system carries a 32% risk of requiring a permanent pacemaker, with pre-existing right bundle branch block and larger annulus size being major predictors.
