Riassunto analitico
In the last years in the interventions of surgical aortic valve replacemant there was a substantial shift worldwide torward the use of bioposthesis rather than mechanical valve also in younger patients, to avoid life-time oral anticoagulation. However bioprostheses have limited durability and most are expected to degenerate and eventually fail within ten to twenty years. Valve-in-Valve with TAVR is emerging as a minimal invasive procedure alternative to surgical redo. I presented a case of Valve-in-Valve procedure (THV-in-SHV) for bioprosthesis aortic valve disfunction complicated by severe paravalvular leak with the need of a second Valve-in-Valve procedure (THV-in-THV) that resulted in patient-prosthesis mismatch. This case is emblematic of the next future in wich we will treat an increasingly number of younger patients with a degenerate bioprosthetic SHV (or THV) that could be need one or more re-interventions during their life-time as well as coronary interventions. So it will be more and more important to develop procedural protocols, universally recognized, and, on the other hand, a more tailored and meticolous planning of the procedure, and maybe also a new generation of devices more performing.
