Evaluation of parameters when choosing between redo surgical aortic valve replacement (SAVR) and valve-in-valve transcatheter aortic valve replacement (ViV TAVR)
| Parameters/Features | ViV TAVR | Redo SAVR |
|---|---|---|
| High surgical risk | √ | |
| Age > 80 years | √ | |
| Concurrent surgical interventions | √ | |
| PVL | √ | |
| Small ID and PPM | √ | |
| Feasibility of BVF | √ | |
| Other risk of coronary obstruction, valve malposition and aortic root injury | √ | |
| Calcific aortic root or hostile chest | √ | |
| Favorable coronary anatomy | √ |
BVF: balloon valve fracture; ID: internal diameter; PPM: patient-prosthesis mismatch; PVL: paravalvular leak
