| Frontal aortic root tilt angle (°) | 48.9 (9.8) | 49.0 (9.3) | 48.9 (9.9) |
| Left ventricle to aortic root angle: three-chamber plane (°) | 128.1 (8.5) | 127.3 (8.9) | 128.3 (8.4) |
| Membranous septum height (mm) | 4.3 (1.7) | 4.2 (1.4) | 4.3 (1.7) |
| Inferior distance (mm) | 3.0 (2.1) | 2.8 (1.9) | 3.1 (2.1) |
| Valve implantation depth (mm) | 5.7 (2.6) | 6.4 (2.9) | 5.5 (2.5) |
| Δ Inferior distance to implantation depth (mm) | −2.7 (3.3) | −3.6 (3.4) | −2.5 (3.2) |
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.
