Dextrocardia is a very rare congenital malposition, and most cardiologists are not familiar with the radiographic angiograms of this condition. Here, we first report a case of dextrocardia with a chronic total occlusion (CTO) lesion undergoing retrograde percutaneous coronary intervention (PCI). Significant difficulties in lesion interpretation and device manipulation were encountered with the original angiograms. These challenges were not significantly improved until we adopted the double-inversion technique. The procedure was finally accomplished by using the kissing wire technique with a poor angle of attack. Retrograde CTO PCI for patients with dextrocardia is feasible with adequate techniques.
右旋心是一种非常罕见的先天性位置异常，大多数心脏病专家对这种情况的 X 射线血管造影并不熟悉。在这里，我们首次报告了一例右旋心合并慢性完全闭塞（CTO）病变患者进行逆行经皮冠状动脉介入治疗（PCI）的病例。原始血管造影图像在病变解读和器械操作方面存在明显困难。直到我们采用了双反转技术，这些挑战才得到显著改善。最终采用吻线技术，以较差的攻击角度完成了手术。对于右旋心患者，采用适当的技术进行逆行 CTO PCI 是可行的。
