报道的室间隔完整的肺动脉瓣闭锁的病例，死前血管造影显示心肌内憩室和窦状隙盲目终止于心肌或与冠状动脉相通。死后证实是通过连续的心肌组织切片和右室腔内注射造影剂，以及造影剂从冠状静脉口进入主动脉根部的影像显示。由于在这些病例中，右室的收缩压必须从胎儿早期就开始升高，因此，憩室和窦状窦代表小梁间隙的持续和扩张及其与冠状动脉系统的联系。
In the cases of pulmonary-valve atresia with intact ventricular septum reported, intramyocardial diverticula and sinusoids ending blindly in the myocardium or communicating with the coronary arteries were demonstrated ante mortem by angiography. Post-mortem confirmation was by serial histologic section of the myocardium and by intracavitary injection of contrast material into the right ventricle, with radiographic visualization of communication and flow of contrast material from the coronary ostia into the aortic root. Since the systolic pressure in the right ventricle must be elevated from early fetal life in these cases it is suggested that the diverticula and sinusoids represent persistence and ectasia of inter-trabecular spaces and their communications with the coronary-artery system.
