For the patients with a relatively slow heart rate,the frequency of opening and closing of biological valves and the number of impact of mechanical stress upon biological valves were relatively less,so the mechanical wear was reduced.The question is whether this can slow the failure and calcification of the biological valve.A retrospective analysis of 92 biological mitral valve replacement (MVR) cases during the period of 1996-2003 was carried out.
