Large Annuloplasty Rings Facilitate Mitral Valve Repair in Barlow’s Disease

摘要: Background Excess leaflet tissue in Barlow's disease predisposes patients to left ventricular outflow tract obstruction and residual mitral regurgitation after valve repair as a result of systolic anterior motion the leaflet. In addition conventional techniques such sliding plasty shortening, our approach has included use large remodeling annuloplasty rings (up size 40 mm). We report experience with disease. Methods From January 2002 December 2005, 67 (46 men 21 women; median age, 55 years; range, 22 85 years), mean ejection fraction 0.55 ± 0.08, grade 3+ or greater underwent repair. All had Carpentier type II dysfunction, (n = 2), posterior 41), bileaflet 24) prolapse. Predominant reconstructive were plasty/plication 65), triangular resection 16), chordal transfer 25). Concomitant procedures coronary artery bypass grafting surgery 8), tricuspid 20), aortic replacement 3), CryoMaze 22). Results Mitral was successfully completed all patients. Annuloplasty ring 36 mm 17), 38 22), 28). Predischarge transthoracic echocardiography showed absence 67), no trace 62), mild 5). There operative mortality. Conclusions can be predictably performed excellent early outcomes. Large help minimize risk are an important adjunct established this patient cohort annular excess tissue.
