Objectives: The Ross procedure has received increasing interest as an attractive alternative to a prosthetic aortic valve. Given its presumably greater resistance to infection, the pulmonary autograft is theoretically preferable for active endocarditis. The objective of this retrospective study was to present our experience in aortic valve endocarditis treated using the Ross procedure.
Methods: Between May 1997 and February 2011, the Ross procedure was performed on 142 patients in our institution. Twenty-eight patients had aortic valve endocarditis at the time of operation. Fourteen patients had urgent or emergency procedures, and 13 had active disease at the time of surgery. Twelve patients were alcoholics and/or drug addicts. Eight patients had an abscess of the aortic annulus. Clinical follow-up was complete.
Results: Hospital mortality was 10.7%. Overall patient survival (± standard deviation) was 47 ± 13% at 10 years with no cardiac-related death during the mean follow-up of 6.4 ± 4.2 years. There were 3 cases of recurrent endocarditis including anterior mitral leaflets endocarditis and right-sided endocarditis to another germ in a drug addict. Four patients required further surgery, 2 on the pulmonary autograft; 18 of the 19 survivors were in New York Heart Association class I. At the final investigation, all patients had no or grade I autograft regurgitation. The mean pressure gradient across the homograft was 9 ± 7.5, 11 ± 9.5 and 15 ± 9.5 mmHg, respectively, for patients between 0-3, 4-9 and >9 years.
Conclusions: Endocarditis can be treated with good results using the Ross procedure, with a very low rate of recurrence of endocarditis.
