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.
