| Abstract: |
Background: Transcatheter Aortic Valve Implantation (TAVI) is a well-established therapy for severe aortic stenosis but is frequently complicated by cardiac conduction disturbances, often necessitating permanent pacemaker implantation (PPM). Pre-procedural Computed Tomography (CT) offers key insights into anatomical risk factors. Objectives: This study aimed to identify predictors of post-TAVI electrical abnormalities (new-onset LBBB and high-grade AV block) and correlate pre-TAVI CT features with post-operative mechanical trauma-related complications. Methods: This prospective cohort study enrolled 60 consecutive adults undergoing TAVI. All patients had pre- and post-procedural ECG and invasive electrophysiology (IEP). CT measurements included Aortic Valve Calcium Scoring (AVCS), membranous septum length, and annular geometry. Primary outcomes were new LBBB and complete AV block (CAVB) requiring PPM. Results: Post-procedure, QRS duration (94.8±9.9ms vs. 99.6±12.9ms, P=0.038) and PR interval (158.6±12.2ms vs. 178.1±15.2ms, P |
