초록

To develop the supplementary heart valve which could reduce the complications of prosthetic heart valve, in vitro experiments were performed to analyze the movement of the supplementary valves. The autologous pericardium was attached to deficient portion of the porcine valve which was dissected completely and partially. The instantaneous motion of the leaflet was pictured by the 35mm camera and the pressure drop through the valve and cardiac output were measured in mock circulatory system. The durability of the valves were tested in severe hemodynamic conditions.
