The small coronary arteries of two patients with alcoholic cardiomyopathy were studied by means of fine particle barium injection and soft x-ray technic. The spatial architecture of these small arteries which penetrated into the depth of the right and left ventricular myocardium were normal. Their lumina were somewhat dilated and their luminal surfaces were smooth. The "tree circulatory units" were described from this study and were found to be normal. The left ventricular myocardium was richly supplied with small arteries, whereas the myocardium of the right ventricle was not so richly supplied. The myocardium of the papillary muscles and the trabeculae carneae of the left ventricle also had a good supply of small arteries, as did the remote endocardial myocardial appendages. Numerous fine hair-like arteries extended to the epicardial myocardium of the right ventricle to form a brush-like appearance.
通过微粒钡注射和软X射线技术研究了两名酒精性心肌病患者的小冠状动脉。这些深入左右心室心肌的小动脉的空间结构正常。它们的管腔有些扩张，管腔表面光滑。本研究描述了“树状循环单位”，发现其正常。左心室心肌有丰富的小动脉供应，而右心室心肌的供应则不那么丰富。左心室乳头肌和肉柱的心肌也有良好的小动脉供应，远端心内膜心肌附属物也是如此。许多细小的毛发状动脉延伸至右心室的心外膜心肌，形成刷状外观。
