[Isolated mitral valve substitution with Beall prosthesis. Long term results].
During a three-year period (1970 to 1973) the Beall mitral prosthesis (103, 104 & 105 series) was used in 97 patients for isolated mitral valve replacement. The early surgical mortality rate within the first 30 days of operation was 11.34%. Among the 86 survivors, 7 developed thromboembolic complications (8.14 per cent), and there were 20 late deaths. Incidence of other complications such as prosthetic malfunction and significant intravascular hemolysis are commented. The 92.42 per cent of the late survivors are in Class I or II of the N.Y.H.A. functional classification.
