Acute Aortic Valve Endocarditis: Long-Term Results Of The Ross Procedure, Bioprothetic Or Mechanical Valve Replacement

Introduction: Acute aortic valve endocarditis (IE) is a severe disease, with an early mortality rate ranging from 15% to 20%. In young adults, the choice of valvular substitute remains controversial. Hypothesis: The objective of our study was to compare the outcome of the surgical treatment of acute aortic IE in young adults using the Ross procedure, a bioprosthesis or a mechanical prosthesis replacement. Methods: From 1994 to 2016, we retrospectively included 105 adult patients under 50 years of age, who underwent surgical treatment of an IE. Mean age was 41 years (32-46), mostly men (88%). Our primary composite endpoint was the event-free survival (death, recurrence of IE, reoperation, severe haemorrhagic or thromboembolic event). Ross procedure were performed in 32 patients, bioprosthesis were implanted in 35 patients and mechanical prosthesis in 38 patients. Results: Hospital mortality rate was 7% with no significant differences according to the type of surgical procedure. The 10-year event-free survi...
