Mitral valve annuloplasty was performed using a supporting strip or ring of polytetrafluoroethylene cut from a vascular graft. From October 1995 to September 1997, this material was used in 42 patients (mean age, 17.5 ± 5.9 years) with rheumatic mitral valve disease. The technique was found to be useful, easy, safe, cost effective, and it preserved the physiological function of the mitral valve annulus.
