Valve-in-Valve Transcatheter Aortic Valve Implantation Versus Redo SAVR for Degenerated Biological Prosthesis: A Narrative Review Stating Our Experience.

ABSTRACT: Surgical aortic valve replacement (SAVR) is still the gold-standard treatment for aortic stenosis. However, the increasing use of biological prostheses, even in young patients, makes Valve-in-Valve (ViV) transcatheter aortic valve implantation (TAVI) an attractive option compared to redo SAVR, thanks to its lower invasiveness and sometimes greater safety. However, there are several technical and anatomical aspects to consider. Therefore, the aim of our review is to examine the main mechanisms responsible for the degeneration of biological prostheses and, subsequently, to analyze the hemodynamic (transvalvular gradients, patient-prosthesis mismatch, paravalvular leakage) and technical (risk of coronary obstruction, prosthetic implantation strategy) aspects that most influence the procedure'
