ROURA, Pablo et al. Aortic Valve Replacement Using the Ross Procedure: a 13-Year Experience. Rev. argent. cardiol. [online]. 2010, vol.78, n.6, pp.485-491. ISSN 1850-3748.

Background The Ross procedure has been used for decades for the treatment of aortic valve disease. Despite the promising outcomes of this technique, its limited durability is one of the major drawbacks against its massive indication. Objective To analyze the outcomes of the Ross procedure in our oenter. Material and Methods We conducted a retrospective study in a cohort of patients. From July 1995 to May 2008, 198 patients underwent Ross procedure with aortic root replacement technique. Kaplan-Meier method was used to analyze the events associated with the valve, and the variables were analyzed using the log-rank test and Cox model. Results Mean age was 39± 13 years and 77% were raen. The procedure was indicated due to aortic stenosis (58%) and aortic regurgitation (42%). In-hospital mortality was 2.5% (5 patients). Complete follow-up at 10 years was achieved in 93% of the first 165 patients. Survival at 10 years was 94.8% (95% CI, 89-98) After 10 years, 95% (95% CI, 84-98) of patients did not present endocarditis and 91% (95% CI, 86-96) had no valve-related events. Five patients required reoperation, 4 due to autograft dysfunction and disease of other valves. Conclusions Ross procedure has a low event rate after 13 years and should be considered for the treatment of aortic valve disease in selected patients.
