title: Some comments on heart valve testing and other observations.
abstract: Testing of cardiac valve prostheses has been conducted primarily to ascertain flow patterns, fatigue, and thrombogenicity. The authors present their observations on valve dynamics, strain factors, and clinical correlations resulting from extensive experience in testing valve prostheses. They emphasize the need to retest valves that have undergone even minor modification.
