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.
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。
