The study included 322 patients with bifurcation lesion of the coronary bed who had angioplasty by the conventional procedure by employing one balloon. The authors analyze whether there is a correlation of balloon coronary angiographic findings with the following X-ray morphological characteristics: the origin of a lateral branch from the stenotic segment of the coronary artery, that of the branch at a distance of no more than 10 mm proximal or distal to stenosis, the angle of branch origin. Based on the findings, it was concluded that the origin of the branch from the stenotic segment is a factor that limits an angiographic success of dilatation of the great coronary vessel. The origin of the branch 10 mm proximal or distal to stenosis does not affect the angiographic success of the procedure. The risk factors of lateral branch lesion include the origin of the branch from a stenotic segment, an angle of branch origin of over 45 degrees.
该研究纳入了322例采用单球囊常规方法进行血管成形术的冠状动脉床分叉病变患者。作者分析了球囊冠状动脉造影结果与以下X线形态学特征之间是否存在相关性：冠状动脉狭窄段侧支的起源、狭窄近端或远端不超过10 mm处分支的起源、分支起源角度。基于这些发现，得出的结论是，狭窄段分支的起源是限制大冠状动脉血管扩张造影成功的一个因素。狭窄近端或远端10 mm处分支的起源不影响该手术的造影成功。侧支病变的危险因素包括狭窄段分支的起源、分支起源角度超过45度。
