Mechanical valve versus bioprosthesis-Clinical and hemodynamic evaluation

Abstract

We evaluated clinical and hemodynamic results in the patients undergoing AVR with Bjork-Shiley prosthesis and - propiolactone preserved aortic homocaraft, and MVR with Hancock valve, aortic homogaft, and dura mater valve. We concluded that mechanical valve was the prosthesis of choice in aortic as well as in mitral position.
