Implantation of the LV lead for biventricular pacing can be challenging, time consuming, and often requires extensive fluoroscopy time. A conventional diagnostic 5 Fr left Amplatz catheter was used to cannulate the coronary sinus in 15 consecutive patients undergoing implantation of a biventricular pacemaker. When the coronary sinus was cannulated, the proximal end of the Amplatz catheter was cut and the coronary sinus sheath was passed over the Amplatz catheter that was then removed. Coronary sinus cannulation was achieved in all 15 patients with a mean fluoroscopy time of 3.34 +/- 1.9 minutes. Subsequent implantation of a biventricular pacemaker was successful and free of complications in all the 15 patients.
双心室起搏左心室电极的植入可能具有挑战性、耗时，且通常需要较长的透视时间。在连续15例接受双心室起搏器植入的患者中，使用传统的5F诊断性左Amplatz导管进行冠状静脉窦插管。当冠状静脉窦插管成功后，将Amplatz导管近端切断，然后将冠状静脉窦鞘套在Amplatz导管上并移除该导管。15例患者均成功完成冠状静脉窦插管，平均透视时间为3.34±1.9分钟。随后，15例患者双心室起搏器的植入均获成功且无并发症。
