右冠状动脉(RCA Right Coronary [ˈkɒrənri] 冠状的Artery['ɑ:təri]动脉)来自于右主动脉窦,经肺动脉根部及右心耳之间,沿右冠状沟行走,绕过心右缘,继续在膈面的冠状沟内行走; 右冠状动脉在房室交点的附近发出了后降支/又称为后室间支(PDA ...
12.The patient underwent emergent cardiac surgery to repair the aortic wall and bypass the proximal portion of right coronary artery (RCA).这病人紧急接受心脏手术来修复主动脉壁并对右冠状动脉近端做绕道。 13.Extending across the middle of the picture to the right is the anterior descending branch....
The RCA arose from the left coronary cuspid, and a narrow orifice was suspected (Figure 1D). MSCT revealed abnormal orifice of the RCA from the left coronary sinus, with inter- arterial course and narrowed ostium (Figures 1E&F). Coronary artery bypass surgery was performed and di- rect ...
