Bioprosthetic Mitral Valve Replacement in Patients Aged 65 Years or Younger: Long-Term Outcomes With the Carpentier–Edwards PERIMOUNT Pericardial Valve

This report provides long-term outcome data on the Perimount valve implanted in the mitral position in patients 65 years of age or less. The expected valve durability was 14.2 years, which compares favourably with other prosthetic valves. Long term mortality was considered valve-related in 1.3% per valve-years, with an overall mortality of 4% per valve-years. The authors provide useful predictions of valve degeneration rates and need for reoperative surgery.
