    The flow characteristics of most prosthetic mitral valves recommended for clinical use have not been adequately investigated. As a result vital information about their performance is lacking and, until this is published, comparisons between different prostheses cannot easily be made. In this paper the design and construction of a suitable rig for the testing of such valves is described. The results obtained will be presented in a subsequent paper.
