Active Aortic Endocarditis in Young Adults: Long-term Results of the Ross Procedure.

ABSTRACT

BACKGROUND: The best valvular substitute remains controversial in young adults with active aortic valve endocarditis. The Ross procedure has gained interest because of its theoretical resistance to infection. We aimed to report our long-term outcomes of the Ross procedure in this indication. METHODS: Between March 1992 and January 2019, 511 patients underwent a Ross procedure in our institution. Among them, we included 38 patients who suffered from an active aortic valve infective endocarditis. The mean age was 33.9 ± 8.1 years. Six patients had emergent procedures and 17 patients had perivalvular involvement. A pulmonary autograft was implanted using the full root technique in 78.9% of patients. Median follow-up was 12 (interquartile range, 1.75-16.25) years. RESULTS: The hospital mortality rate was 5.3%. Estimated overall survival was 84.2% ± 6.6% at 10 years. There were 2 cases of recurrent endocarditis, both requiring reoperation. Six other patients required reoperation on an autograft or homograft. Estimated freedom from recurrent endocarditis or reoperation was 89.4% ± 5.9% at 10 years. CONCLUSIONS: In experienced centers, the Ross procedure is a reliable alternative to prosthetic or homograft valve replacement in young adults experiencing active aortic valve endocarditis, with a low operative risk and good long-term results.
