Directional Radial Force Alignment Predicts Pacemaker Implantation After Balloon-Expandable Transcatheter Aortic Valve Implantation: A Computed Tomography-Based Biomechanical Study.
The Vectorial Angle is a novel, independent pre-procedural predictor of PPM after balloon-expandable TAVI, highlighting that the spatial orientation of the valve's maximal radial force relative to the conduction tissue is a potential anatomical determinant associated with conduction-system vulnerability, complementing...
