From:  Valve-in-valve transcatheter aortic valve replacement: state of art

 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
