This study describes intracardiac migration of epicardial pacemaker leads after open heart surgery in 2 patients. Discovery of these pacemaker leads or remnants led to diagnostic confusion until an appropriate diagnosis was established by both invasive and noninvasive means. Intracardiac migration of epicardial pacemaker leads has only rarely been reported. Migration to other noncardiac organs has also been reported infrequently. Awareness of this unusual occurrence should avoid postoperative confusion in recognizing origin of said artifacts.
本研究描述了 2 例开胸心脏手术后心外膜起搏器导线的心脏内迁移。这些起搏器导线或残端的发现导致了诊断上的混淆，直到通过有创和无创手段确立了适当的诊断。心外膜起搏器导线的心脏内迁移很少有报道。起搏器导线迁移至其他非心脏器官也很少有报道。认识到这种不常见的情况应该可以避免术后在识别这些伪影的来源时产生混淆。
