A modified technique for mitral valve replacement.
Between 1976 and 1983 254 mitral valve prostheses (243 Björk-Shiley and 14 bioprostheses) were implanted in 252 patients using a modified technique. The age of patients varied from 26-72 years (mean 56 +/- 18 years). This technique allows an equidistant placement of sutures and accurate stitching of mitral valve annulus to the prosthetic valve ring. Follow-up averaged 67 +/- 21.6 months (3-7 years). Linearized aseptic dehiscence was 0.17 per 100 patient years. This technique was especially useful in patients with small left atrium and minimised the risk of a major prosthetic detachment.
