| Procedural mortality | 1/223 (0.4) | 2/215 (0.9) | 0.617 |
| Procedure success rate* | 218/223 (97.8) | 212/215 (98.6) | 0.724 |
| Conversion to surgery** | 4/223 (1.8) | 1/215 (0.5) | 0.373 |
| Coronary obstruction during procedure | 1/223 (0.4) | 5/215 (2.3) | 0.116 |
| >1 valve implanted | 0/223 (0) | 1/215 (0.5) | 0.491 |
| New permanent pacemaker | 6/223 (2.7) | 6/215 (2.8) | 1.000 |
| Major vascular complication*** | 1/223 (0.4) | 0/215 (0) | 1.000 |
*Procedure success is defined as follows: successful valve implantation in the aortic valve position without conversion to surgery and patient survival.
**1 operation converted to elective surgery and 4 emergency surgery.
