Background : Prosthetic annuloplasty rings are used for the reconstruction of the mitral valve annulus. However, there is controversy over the best ring to use for reconstruction. In this study, we evaluated the long term result of using a Teflon felt strip as an alternative to commercial rings.
Materials & Methods : From 1996 to 2007, we enrolled 47 patients with pure mitral regurgitation greater than grade III. All patients had an ejection fraction of 40% or more. Patients with congenital heart disease or other valvular heart disease were excluded from this study. They were divided into two groups; the commercial ring group (Group CR) and the Teflon felt ring group (Group TF).
Results : There was no mortality. The postoperative echocardiography showed no significant change in the overall ejection fraction (from 58.0±11.2% to 42.8±8.4%). There were no significant differences between the two groups with regard to morbidity, the reoperation rate and recurrence of mitral regurgitation greater than grade II.
Conclusion : The long term results from this study showed that posterior mitral annuloplasty using Teflon felt had similar results compared to annuloplasty using commercial rings.
