关于国人心肌桥的初步观察

A STUDY OF THE MYOCARDIAL BRIDGES ON THE CORONARY ARTERIES IN THE CHINESE

关于心肌桥这一名称,首先由P.Polacek[1]于1959年提出制订的。就是在心肌层表面,有时可见一处或数处的心肌纤维束跨过心冠状血管表面,其形似桥,故有心肌桥的命名。1913年J.Tandler[2],1922年A.Crainicianu[3].

1.The myocardial bridges on the coronaty arteries of 100 hearts were studied.These formations occur in 66.3±4.76%of the cases and were located as follows:(1)On the left coronary artery:60.0±4.98%was found on the r.interventri-cularis ant.;6.1±2.41%on the r.obliquus ventriculi sin.;1.0±1.00%on the r.ter-minalis;9.1±2.90%on the r.marginalis.(2)On the right coronary artery:10.0±3.00%on the r.interventricularis post.;5.0±2.18%on the r.anteriores ventriculi dex.;3.0±1.71%on the r.marginalis.(3)The rest:3.1±1.76%on the v.cordis magna;1.0±1.00%on the v.cordismedia.2.Microscopic examination of 5 hearts showed that the myocardial bridge is a partof the superficial myocardial layer.3.The result were discussed with those from other authors.
