Clinical Impact of Persistent Left Bundle-Branch Block After Transcatheter Aortic Valve Implantation With CoreValve Revalving System.

The article presents a study which examines the adverse effect of persistent left bundle-branch block (LBBB) following a transcatheter aortic valve implantation with the use of CoreValve Revalving System. The study uses survival analyses and inherent log-rank tests to determine the clinical impact of LBBB. Results show that LBBB does not affect patients treated with transcatheter aortic valve implantation with CoreValve Revalving System.
