Abstract

ObjectivesTo examine the late outcomes of valve-sparing root replacement and concomitant mitral valve repair in patients who have been followed prospectively for more than 2 decades. MethodsFrom 1992 to 2020, 54 consecutive patients (mean age, 47 ± 16 years; 80% men) underwent valve-sparing root replacement (45 reimplantation and 9 remodeling) with concomitant repair of the mitral valve. Patients were followed prospectively for a median of 9 years (IQR, 3-14 years). ResultsNo patient experienced perioperative death or stroke. There were 3 late deaths and the 15-year overall survival was 96.0% (95% CI, 74.8%-99.4%), similar to the age- and sex-matched population. Over the follow-up period, 6 patients had reoperation of the aortic valve and 3 on the mitral valve. Of those, 2 had reoperation on both aortic and mitral valves for a total of 7 reoperations in this cohort. The cumulative proportion of reoperation at 10 years of either or both valves were as follows: aortic valve 11.4% (95% CI, 3.9%-33.3%), mitral valve 4.2% (95% CI, 0.6%-28.4%), and both valves 11.4% (95% CI, 3.9%-33.3%). The estimated probability of developing moderate/severe aortic insufficiency at 15 years was 18.5% (95% CI, 9.0%-34.2%). On final echocardiographic follow-up, none of the patients had developed moderate/severe mitral regurgitation. ConclusionsIn this single-center series of concomitant valve-sparing root replacement and mitral valve repair, we observed excellent clinical outcomes with a low risk of death or valve-related complications. Continued surveillance of late valve function is necessary.
