为给临床心脏电生理检查及射频导管消融治疗心律失常提供解剖学依据,对30例成人心标本进行了观测.发现冠状窦口的纵径为17.79±4.66mm,横径为8.75±3.39mm.冠状窦开口朝向上或朝向水平方向者占70.00%;开口朝下者占30.00%.冠状窦瓣的高度为5.31±4.18mm.冠状窦各点距二尖瓣环的距离可分为递减型、稳定型及不规则型三种类型.并就有关的临床应用问题进行了讨论.
In order to provide anatomical basis for clinical cardiac electrophysiological examination and radiofrequency catheter ablation for arrhythmia, 30 adult cardiac samples were observed and found that the longitudinal diameter of coronary sinus ostium was 17.79 ± 4.66mm and the transverse diameter was 8.75 ± 3.39mm. Coronal sinus opening toward or towards the horizontal direction accounted for 70.00%; opening down accounted for 30.00% .The height of the coronary sinus is 5.31 ± 4.18mm.The distance between the coronary sinus points from the mitral annulus can be divided into decreasing type, Stable and irregular three types, and discussed the clinical application issues.
