The primary aim of the study is a 5-year comparison between SAVR and surgical TAVR: we hypothesize to report a 10% superiority in terms of all-cause mortality in favor of SAVR vs TAVR. For the purpose of this study, patients will be consecutively enrolled for a 2-year period, and will be followed-up for a minimum of 5 years after the index surgical treatment. Maximum follow-up length will be 10 years after surgery.
