摘　　要：本病例为既往行三尖瓣金属瓣膜置换术后出现完全性房室传导阻滞经冠状静脉实现DDD起搏模式的患者,4年后出现冠状静脉导线脱位、起搏阈值升高、起搏器电量耗竭。拟行新冠状静脉电极植入过程中发现冠状静脉内存在严重狭窄,通过球囊扩张技术实现了新左心室电极植入。This case involves a patient who underwent metal tricuspid valve replacement and developed complete atrioventricular block,subsequently managed with DDD pacing mode via the coronary sinus.Four years postoperatively,the patient experienced coronary sinus lead dislodgement,increased pacing threshold,and pacemaker battery depletion.During the attempted implantation of a new coronary sinus electrode,severe stenosis within the coronary sinus was discovered.A new left ventricular electrode was successfully implanted with balloon dilation technique.
