1例53岁男性镜像右位心患者接受了铊-201(TL-201)负荷重分布心肌灌注单光子发射计算机断层扫描(SPECT)。右半胸心电图显示持续完全性左束支传导阻滞。Tl-201应力重分布SPECT图像显示前间隔、间隔和间隔下壁血流灌注异常，并伴有可逆性缺血。术后1个月行冠状动脉造影术，SPECT检查正常。此病例说明镜像右位心合并持续性完全性左束支传导阻滞的患者可见假阳性可逆性血流灌注缺陷。据我们所知，这是第一例镜像右位心和持续性完全性左束支传导阻滞的报告病例，并有TL-201 SPECT发现的假阳性。
A 53-year-old male patient with a previous diagnosis of situs inversus with mirror-image dextrocardia underwent thallium-201 (Tl-201) stress-redistribution myocardial perfusion single photon emission computed tomography (SPECT). Electrocardiogram (ECG) obtained on right hemithorax revealed constant complete left bundle branch block. Tl-201 stress-redistribution SPECT images revealed abnormal perfusion with reversible ischemia in the anteroseptal, septal and inferoseptal walls. Coronary angiography performed 1 month after SPECT study was normal. This case illustrates that false positive reversible perfusion defects can be seen in patients with mirror-image dextrocardia associated with constant complete left bundle branch block. To our knowledge, this is the first reported case of mirror-image dextrocardia and constant complete left bundle branch block with false positive Tl-201 SPECT findings.
