Table 3.
Arrhythmia before and after transcatheter aortic valve replacement (TAVR).
| Before TAVR | without MAD n = 376 | with MAD n = 32 | p-value | |
|---|---|---|---|---|
| Pacemaker | 21 (6 %) | 0 (0 %) | 0.39 | |
| Type of arrhythmia | Atrial fibrillation or flutter | 75 (21 %) | 11 (34 %) | 0.12 |
| Bundle branch block | 91 (26 %) | 4 (13 %) | 0.13 | |
| Atrioventricular block | 60 (17 %) | 6 (19 %) | 0.81 | |
| After TAVR | without MAD n = 355 | with MAD n = 32 | p-value | |
|---|---|---|---|---|
| Permanent pacemaker implantation within 30 days | 66 (19 %) | 4 (13 %) | 0.48 | |
| Type of arrhythmia | Atrial fibrillation or flutter | 58 (20 %) | 8 (29 %) | 0.33 |
| Bundle branch block | 125 (43 %) | 12 (43 %) | 1.00 | |
| Atrioventricular block | 60 (21 %) | 7 (25 %) | 0.63 | |
Cardiac rhythm was assessed in patients without permanent pacemakers only.
