An 8-year-old boy had undergone permanent epicardial pacemaker implantation with a Y-shaped bipolar ventricular lead on day 6 after birth for treatment of congenital complete atrioventricular block. He was found to have pulmonary stenosis and mitral stenosis by follow-up echocardiography. Further studies including computed tomography and cardiac catheterization revealed that the pacemaker lead had completely encircled the cardiac silhouette and was in a state of "cardiac strangulation". We removed the previous pacing leads and generator and implanted a new epicardial dual-chamber pacing system in the right atrium and right ventricle. Additionally, an expanded polytetrafluoroethylene sheet was placed between the new leads and the heart to prevent recurrence of cardiac strangulation.
一名 8 岁男孩在出生后第 6 天因先天性完全性房室传导阻滞接受了永久性心外膜起搏器植入术，使用 Y 形双极心室导线。随访超声心动图发现他患有肺动脉瓣狭窄和二尖瓣狭窄。进一步的研究，包括计算机断层扫描和心导管检查，显示起搏器导线完全环绕心脏轮廓，处于“心脏绞窄”状态。我们取出了之前的起搏导线和发生器，并在心外膜的右心房和右心室植入了新的双腔起搏系统。此外，在新的导线和心脏之间放置了膨体聚四氟乙烯片，以防止心脏绞窄再次发生。
