Abstract

A simulated heart valve (22) root used for training physicians in techniques of implantation of prosthetic heart valves and testing the efficacy of prosthetic heart valves. The simulated heart valve root is made of a flexible, tubular body (30) having an inner wall (36) defining an annular ledge (60) within which the prosthetic heart valve is implanted. Discrete nodes or areas of calcification may be simulated on the annular ledge by using pins (38) having their inner ends a pinhead shape. A simulated aortic root includes alternating cusps (50) and commissures (52) with calcification simulated at least at one of the commissures. A tear (80) in the annular ledge may also be provided which simulates a tear that might occur from a valvuloplasty procedure. A method of testing includes mounting the simulated heart valve root in a flow conduit, implanting a prosthetic heart valve in the root, applying pulsatile flow to the assembly, and monitoring for leaks.
