BackgroundAutograft valve preservation at reoperation may conserve some of the advantages of the Ross procedure. However, results of long-term follow-up are lacking. In this retrospective multicenter study, we present our experience with valve-sparing reoperations after the Ross procedure, with a focus on long-term outcome.MethodsA total of 86 patients from 6 European centers, who underwent valve-sparing reoperation after the Ross procedure between 1997 and 2013, were included in the study.ResultsReoperation was performed a median of 9.1 years after the Ross procedure in patients with a median age of 38.4 years (interquartile range: 27.1-51.6 years). Preoperative severe autograft regurgitation (grade ≥3) was present in 46% of patients. In-hospital mortality was 1%. During a median follow-up of 4.3 years, 3 more patients died of noncardiac causes, resulting in a cumulative survival at 8 years of 89% (95% confidence interval: 65%-97%). Fifteen patients required a reintervention after valve-sparing reoperation, mostly owing to prolapse or retraction of autograft cusps. Freedom from reintervention was 76% (95% confidence interval: 57%-87%) at 8 years. The reintervention hazard was increased in patients who had isolated and/or severe aortic regurgitation at valve-sparing reoperation. In patients without reintervention after valve-sparing autograft reoperation (n = 63), severe aortic regurgitation was present in 3% at last follow-up.ConclusionsValve-sparing autograft reoperations after the Ross procedure carry a low operative risk, with acceptable reintervention rates in the first postoperative decade. Patients with isolated and/or severe autograft regurgitation have an increased hazard of reintervention after valve-sparing reoperation; for these patients, careful preoperative weighing of surgical options is required.Copyright © 2015 The American Association for Thoracic Surgery.
