In the previous experiments it was reported that either the interventricular septum of the free wall of the right ventricle was replaceable with a non-contractile prosthesis. It was also reported that a new chamber constructed on the epicardium had capability of producing a pulsatile pressure. This study was to determine contribution of the septum and the free wall on performance of the right ventricle by using a simulator. Left-ward shift of the interventricular groove was not found along the basal half of the long axis and was limited only along the apical half. Bulging of the septum toward the right ventricular cavity did not occur at all, but on contrary the septum moved toward left, denying contribution of the septal movement to pump action of the right ventricle.
在之前的实验中，有报告称右心室游离壁的室间隔均可被不可收缩的假体替代。还有报告称在心外膜上构建的新腔室具有产生搏动性压力的能力。本研究旨在通过使用模拟器来确定室间隔和游离壁对右心室功能的贡献。在长轴的基底部一半未发现室间沟向左移位，仅在顶端一半受限。室间隔根本没有向右心室腔凸出，相反，室间隔向左移动，这否定了室间隔运动对右心室泵血作用的贡献。
