Abstract
Between February 1985 and April 1993, 79 patients who had isolated MVR with three different kinds of bileaflet valves (St Jude Medical: SJM in 30, Duromedics: DM in 30, CarboMedics: CM in 19) were hemodynamically analyzed in this study. All patients had postoperative cardiac catheterization which was performed at rest and on exercise about 2 months after surgery. There were no significant differences between in three kinds of valves with hemodynamic data, valve function and hemolysis. Three bileaflet valves of SJM, DM and CM have had excellent valve function in mitral position at rest and on exercise.
