PREDICTORS OF CARDIAC CONDUCTION DISTURBANCES AFTER TRANSCATHETER AORTIC VALVE IMPLANTATION USING SELFEXPANDABLE VALVES

Abstract

Background: The advent of transcatheter aortic valve implantation (TAVI) represented a paradigm shift for treating patients with severe symptomatic aortic stenosis (AS) who are at high or prohibitive surgical risk. With the growing experience in this field, the rate of periprocedural complications has decreased over time and TAVI has been increasingly performed with a minimalist approach, evolving into a safe procedure with predictable outcomes. However, unlike other procedural complications, the incidence of conduction disturbances which could be in the form of bundle branch blocks, or atrioventricular blocks, has failed to decrease in recent times, with reports suggesting an increased risk associated with the use of some newer-generation transcatheter valves.
