Patients and Methods
This is a monocentric retrospective study approved by the ethical committee (CER-VD) under the number 2017-00340. From March 2016 to August 2019, all of the patients who benefited from Perceval-S valve implantation in our institution were prospectively considered. The choice to use a Perceval-S valve was left to the operating surgeon, depending on personal preference and the anatomical characteristics cited above. Exclusion criteria were patients < 65 years old, anatomical features outside the manufacturer’s recommendations13, Sievers type 0 BAV, emergencies and combined surgery other than AVR plus coronary artery bypass graft (CABG). Redo operation was not an exclusion criterion.
