Flow patterns around heart valves: a digital computer method for solving the equations of motion

Research output: Contribution to journalArticle


The flow pattern of blood in the heart is intimately connected with the performance of the heart valves. The motions of blood and valve leaflet interact strongly. Points of the valve leaflet are carried along at the local fluid velocity. At the same time, these points exert forces on the fluid which significantly alter the fluid motion. A mathematical method for studying these phenomena is introduced. Projected uses of this technique include the design and computer testing of prosthetic valves. The details of the flow pattern significantly influence valve performance. The flow pattern is not accessible in vivo, however, and in vitro testing chambers usually have rigid walls, unlike the chambers of the heart. The present method can provide an appropriate setting for the systematic variation of the parameters of prosthetic valve design.
