Cardiac Resynchronization therapy (CRT) using coronary sinus (CS) leads is an established method for the therapy of congestive heart failure (CHF) in the case of inter- and intraventricular conduction delays. However implantation of CS leads is somewhat challenging due to a high number of peri- or postoperative dislocations at a rate of about 10%. The retained guidewire technique has been proposed for the implantation of coronary sinus leads for stabilization in case of repetitive intraoperative dislocations. This report describes CS lead and guidewire fracture 2 years after such an implant.
使用冠状静脉窦（CS）导联的心脏再同步治疗（CRT）是治疗伴有室内和室间传导延迟的充血性心力衰竭（CHF）的既定方法。然而，CS导联的植入颇具挑战性，因为围手术期或术后脱位发生率较高，约为10%。对于术中反复脱位的情况，有人提出采用保留导丝技术来植入冠状静脉窦导联以实现稳定。本报告描述了此类植入术后两年冠状静脉窦导联和导丝的断裂情况。
