The purpose of this study is to analyze treatment options for valvular regurgitation with severe left ventricular dysfunction. ⋯ It is concluded that a low EF is not a predictive factor of operative mortality but it influences late survival as do the degree of left ventricular dilatation, etiology in aortic and type of surgery in mitral regurgitation. Alternatives to valvular surgery have been envisaged but information on vasodilators in these patients is scant and results of heart transplantation are known only from a few small series.

Expanded polytetrafluoroethylene sutures have been used for the replacement of chordae tendineae of the mitral valve since 1985 at The Toronto Hospital. This study examines the long term results of mitral valve repair with chordal replacement with this material. ⋯ Expanded polytetrafluoroethylene sutures are excellent for chordal replacement during mitral valve repair and do not fail during the first decade following surgery. This material has allowed us to increase the probability of successful mitral valve repair in patients with degenerative disease of the mitral valve and prolapse of both leaflets.
