Abstract：
BACKGROUND: Congenitally corrected transposition of the great arteries (ccTGA) is a rare cardiac anomaly and can lead to abnormal electrical activity of the heart. The implant of a pacemaker in such patients is more complicated than conventional operations. This case report of an adult with ccTGA who had a leadless pacemaker implant will provide a reference for diagnosing and treating such patients.
METHODS: A 50-year-old male patient was admitted to hospital having experienced intermittent vision loss for a month. An electrocardiogram and Holter monitoring showed intermittent third-degree atrioventricular block, and echocardiography, cardiac computed tomography and cardiac magnetic resonance imaging confirmed a diagnosis of ccTGA. A leadless pacemaker was successfully implanted into the patient\'s anatomical left ventricle, and the postoperative parameters were stable.
CONCLUSIONS: Implanting a leadless pacemaker into a patient with a rare anatomical and electrophysiological abnormality, such as ccTGA, is feasible and efficacious, but preoperative imaging evaluation is of considerable importance.

摘要：
背景：先天性矫正的大动脉转位（ccTGA）是一种罕见的心脏异常，可导致心脏异常的电活动。在这样的患者中植入起搏器比常规手术更复杂。一例ccTGA患者无引线起搏器植入的病例报告将为此类患者的诊断和治疗提供参考。
方法：一名50岁的男性患者因间歇性视力丧失一个月而入院。心电图和动态心电图监测显示间歇性三度房室传导阻滞，还有超声心动图,心脏计算机断层扫描和心脏磁共振成像证实了ccTGA的诊断。无引线起搏器成功植入患者的解剖左心室,术后参数稳定。
结论：将无导线起搏器植入罕见解剖和电生理异常的患者体内，例如ccTGA，是可行和有效的，但术前影像学评估相当重要。
