To study the angiographic anatomy of human coronary veins and the possibility of epicardial venous mapping through microelectrode catheters.
We evaluated 30 patients with sustained ventricular tachycardia using a catheter which provided occlusion of the coronary sinus ostium during venous angiography. They were 25 males, 5 females, ages ranging from 24 to 76 years (mean = 52.7). The veins were studied according to their number, caliber and distribution in the anterior and posterior wall of the left ventricle.
Coronary sinus was catheterized in all patients. No discomfort or complication were observed. The number of veins from posterior wall of the left ventricle was 3.1 and anterior wall, 1.9, p < 0.05. The caliber of the coronary veins were: anterior interventricular vein (distal segment = 1.19 +/- 0.22 mm, middle segment = 1.65 +/- 0.35 mm), posterior interventricular vein (distal segment = 1.83 +/- 0.47 mm, middle segment = 2.00 +/- 0.52 mm), left posterior vein (distal segment = 1.45 +/- 0.25 mm, middle segment = 2.49 +/- 0.92 mm); p < 0.05.
The balloon occlusion technique for coronary venous angiography is feasible and safe. The number and the caliber (distal and middle) of the veins from the posterior wall of the left ventricle were significantly greater than those from the anterior wall. Anatomic conditions for venous epicardial mapping are more adequate in the posterior wall of the left ventricle.
研究人类冠状静脉的血管造影解剖结构以及通过微电极导管进行心外膜静脉标测的可能性。
我们使用一种在静脉血管造影期间可闭塞冠状窦口的导管对30例持续性室性心动过速患者进行了评估。他们中男性25例，女性5例，年龄在24至76岁之间（平均52.7岁）。根据静脉在左心室前壁和后壁的数量、管径及分布情况进行研究。
所有患者均成功进行了冠状窦插管。未观察到不适或并发症。左心室后壁的静脉数量为3.1条，前壁为1.9条，p<0.05。冠状静脉的管径如下：前室间静脉（远端段=1.19±0.22mm，中段=1.65±0.35mm），后室间静脉（远端段=1.83±0.47mm，中段=2.00±0.52mm），左后静脉（远端段=1.45±0.25mm，中段=2.49±0.92mm）；p<0.05。
冠状静脉血管造影的球囊闭塞技术可行且安全。左心室后壁静脉的数量和管径（远端和中段）明显大于前壁。左心室后壁的心外膜静脉标测的解剖条件更为合适。
