  • Values are mean (SD).

  • PPI, permanent pacemaker insertion; TAVI, transcatheter aortic valve implantation; Δ Inferior distance to implantation depth, difference between inferior distance and valve implantation depth; Inferior distance, virtual basal ring to muscular ventricular septum height.
