Evaluation of parameters when choosing between redo surgical aortic valve replacement (SAVR) and valve-in-valve transcatheter aortic valve replacement (ViV TAVR)

Parameters/FeaturesViV TAVRRedo 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
