Abstract
One hundred eighty‐eight Mitroflow pericardial valves, implanted on 166 patients from March 1983 to December 1986, have been followed for a total of 4316 patients x months. Mortality rate in the first three postoperative months is approximately 10% related to noncardiac complications. One hundred forty‐nine patients are living at the start of the follow up period. During that period, one valve was explanted after 22 months for a cusp tear. The rate of thrombo embolic episode is minimal, six cases, as 47% are free of any anticoagulant therapy. One patient, operated upon for active SBE, required additional surgery 2 months later for a prosthetic infection. The present results suggest that early primary failure of Mitroflow valve is quite unfrequent.
