The double-orifice technique as a standardized approach to treat mitral regurgitation due to severe myxomatous disease: surgical technique.

摘要: Objectives: Mitral-valve repair in Barlow’s disease is challenging; conventional techniques are difficult to perform, and there a high risk of postoperative suboptimal result. Double-orifice has been applied standardized approach treat patients with severe mitral regurgitation bileaflet prolapse due disease. Methods: Since 1993, 82 underwent correction applying the edge-to-edge concept. They were submitted double-orifice fashion, suturing middle portions both leaflets. Results: There no hospital deaths. The was unsatisfactory one patient who valve replacement soon after repair. mean area 3.7 ^ 0.79 cm 2 against preoperative value 9.2 2.1 . No or mild found all but three showed moderate residual regurgitation. late Freedom from reoperation 86 14% at 5 years. At latest follow-up, New York Heart Association (NYHA) functional class I, echo-Doppler assessment reconstruction stable function patients. Conclusions: can be used as Barlow low good early mid-term results. q 2000 Elsevier Science B.V. All rights reserved.
