A 36-year-old man with a history of hypertrophic obstructive cardiomyopathy presented to the emergency room with "stabbing" chest pain. He had undergone dual-chamber pacemaker implantation in 1993 using an atrial lead (Accufix; Telectronics; Englewood, Colo) and a myomectomy in 1996 during which the distal portion of the atrial lead was removed. Digital fluoroscopy revealed that the retention wire had migrated out of the remaining atrial lead and perforated the right atrium. The retention wire was successfully removed percutaneously. The need for complete removal of the retention wire in the Accufix lead at the time of open-heart surgery is emphasized.
一名有肥厚性梗阻性心肌病病史的36岁男性因“刺痛样”胸痛就诊于急诊室。他于1993年植入双腔起搏器，使用心房导线（Accufix；泰利特电子公司；科罗拉多州恩格尔伍德），并于1996年接受了肌瘤切除术，在此期间心房导线的远端部分被移除。数字荧光透视显示固定线已从剩余的心房导线中移出并穿破右心房。经皮成功移除了固定线。强调了在心脏直视手术时完全移除Accufix导线中固定线的必要性。
