Tóm tắt

BACKGROUND: High-degree atrioventricular block with the need for permanent pacemaker (PPM) implantation represents a frequent complication after transcatheter aortic valve implantation (TAVI). Extension of indication for TAVI toward subjects with lower surgical risk requires reduction of the likelihood for the need for PPM implantation. The aim of the current analysis was to identify predictors of the need for PPM implantation after TAVI. METHODS AND RESULTS: In a cohort of 1500 consecutive patients without a PPM undergoing transfemoral TAVI, clinical and procedural characteristics as well as parameters derived from cardiac computed tomography, such as membranous septal length and calcium volumes of the aortic valve cusps and the left ventricular outflow tract were assessed. Median calcium volume of the aortic valve was 552 mm CONCLUSIONS: The current analysis offers a detailed examination of predictors for the need for PPM implantation after TAVI. Our results may contribute to improved risk stratification on the need for PPM implantation after TAVI.
