摘要
目的:对于经冠状窦途径植入心脏再同步化治疗(CRT)左心室心外膜导线失败的患者,探讨采用经室间隔穿刺的方法植入左心室心内膜导线的安全性和疗效。方法:2例患者因冠状窦畸形经冠状窦途径植入CRT左心室心外膜导线失败,采用经室间隔穿刺的方法植入左心室心内膜导线,随访电极参数及CRT疗效。结果:2例患者均成功采用经室间隔穿刺的方法植入CRT左心室心内膜导线,随访期间电极参数稳定,未见明显不良事件,患者心功能得到改善。结论:针对经冠状窦途径植入CRT左心室心外膜导线失败的患者,采用经室间隔穿刺的方法植入左心室心内膜导线获得成功,但因例数少,该方法的安全性及有效性仍值得进一步研究。
Objectives： Left ventricular（LV） pacing through the coronary sinus is the standard approach for cardiac resynchronization therapy（CRT）. When this route is unavailable, LV endocardial pacing through the interventricular septum may offer a simple alternative solution. We describe the experience of LV endocardial pacing through the interventricular septum in two patients. Methods and Results： Two patients with previous failed coronary sinus lead implantation were included. The surgery was accomplished successfully. At follow-up, thresholds were stable, there were no thromboembolic events and the CRT response was good. Conclusions： LV endocardial pacing through the ventricular septal puncture is a feasible alternative approach for cardiac resynchronization therapy.
