为了测定冠状循环血流量研究心肌的代谢,或了解作用于冠状循环的药理,或选用冠状静脉窦作为进行心房内人工心脏起搏时安置起搏电极心导管的场所,都必需进行冠状静脉窦心导管的检查。但临床上在冠状静脉窦心导管检查时心导管不易进入冠状窦,而在右心房常规右心导管检查时心导管却无意中由右心房进入冠状窦。因此详细了解右心房结构诸如下腔静脉瓣与冠状窦口的关系、冠状窦瓣的构造等解剖学知识,将有助于提高心导管送入的成功率。对于正常人冠状窦口的位
In order to determine the coronary circulation blood flow myocardial metabolism, or to understand the role of the coronary circulation pharmacology, or use of coronary sinus as a place for intra-atrial artificial cardiac pacing placement of cardiac catheterization center, are necessary for coronary sinus heart Catheter examination. However, in clinical coronary sinus catheterization, cardiac catheterization is not easy to enter the coronary sinus, while in the right atrium routine right heart catheterization, cardiac catheterization inadvertently entered the coronary sinus. Therefore, a detailed understanding of the structure of the right atrium, such as the relationship between the inferior vena cava and the coronary ostium, the anatomy of the coronary sinus lobe and other anatomical knowledge, will help to improve the success rate of cardiac catheterization. For normal coronary sinus ostial bits
