ObjectiveMitral valve repair for myxomatous Barlow disease is a challenging procedure requiring complex surgery with less than optimal results. The use of ring-only repair has been previously reported but never analyzed or followed-up. We investigated this simple valve repair approach for patients with Barlow disease and multisegment involvement causing mainly central jet.MethodsOf 572 patients who underwent mitral valve repair for mitral regurgitation at our medical center, 24 with Barlow disease (aged 47 ± 14 years; 46% male) underwent ring-only repair. Patients were characterized by severely enlarged mitral valve annulus, multisegment prolapse involving both leaflets, and demonstrated mainly a central wide regurgitant jet. Surgical technique included only the implantation of a large mitral annuloplasty ring. Early and late outcome results were compared with those of the remaining patients who underwent conventional mitral valve repair for degenerative disease (controls).ResultsAll ring-only patients presented with moderate-severe/severe mitral regurgitation (vena contracta, 0.6 ± 0.1 cm; regurgitation volume, 52 ± 17 mL), with mainly a central jet and almost preserved ejection fraction (59% ± 6%). Cardiopulmonary bypass and crossclamp times were significantly shorter compared with controls (P < .0001). At follow-up (ring-only, 38 ± 36 months and controls, 36 ± 29 months), there were no late deaths in the ring-only group compared with 19 (4%) in the controls. Late follow-up revealed New York Heart Association functional class I or II in 95% of ring-only patients, compared with 90% of controls. Freedom from recurrent moderate or severe mitral regurgitation was 100% and 89% in the ring-only and control groups, respectively.ConclusionsMitral annuloplasty for Barlow disease patients with multisegment involvement and mainly central regurgitant jet is both simple and reproducible with excellent late outcomes.Copyright © 2015 The American Association for Thoracic Surgery.
