Prospective Observational Study on the Accuracy of Predictors of Permanent Pacemaker Secondary to High-Grade Atrioventricular Conduction Block After TAVI (CONDUCT-TAVI)

The incidence of conduction abnormalities remains high after TAVI, and after factoring in anatomic, procedural, and electrophysiological factors, a baseline right bundle branch block and electrophysiology study-derived measures of atrioventricular conduction were the most significant predictors of PPMI. The CONDUCT-TAVI score incorporates these findings to help implanters stratify low-risk patients and tailor follow-up care.
