BACKGROUND
Coronary sinus is the target of an increasing number of percutaneous interventional procedures. Thus, in some patients, conventional cardiac resynchronization therapy (CRT) may not be feasible or preferable, and 'alternative' CRT approaches should be applied.
CASE SUMMARY
We present the case of a successful CRT via direct left bundle branch permanent pacing (LBBP) in a patient with relative contraindication to conventional CRT because of previous percutaneous indirect mitral annuloplasty.
DISCUSSION
LBBP is emerging as a promising technique for physiological cardiac pacing and CRT. It may represent the technique of choice when coronary sinus is not viable for the implant of a conventional left ventricular catheter.
背景
冠状静脉窦是越来越多经皮介入手术的目标。因此，在一些患者中，传统的心脏再同步治疗（CRT）可能不可行或并非首选，应采用“替代”CRT方法。
病例摘要
我们报告了一例通过直接左束支永久起搏（LBBP）成功进行CRT的病例，该患者因既往经皮间接二尖瓣环成形术而存在传统CRT的相对禁忌证。
讨论
LBBP正在成为一种有前景的生理性心脏起搏和CRT技术。当冠状静脉窦无法植入传统的左心室导管时，它可能是首选技术。
