This is a case of an anomalous left circumflex coronary artery (LCX) originating from the right coronary cusp with a retroaortic course in a patient with severe aortic valve stenosis requiring transcatheter aortic valve implantation (TAVI). In the context of TAVI, an anomalous LCX has been described only in a few case reports. In some, the LCX remains unaffected. However, occlusion after TAVI valve deployment has been described. We report pre-procedural imaging and procedural precautions prior to valve deployment in our case in which the LCX remained unaffected by the TAVR valve. More case reports or series are needed to help assess which characteristics are associated with an increased risk of anomalous LCX obstruction.
这是一例异常左旋冠状动脉（LCX）起源于右冠状动脉瓣叶并走行于主动脉后方的病例，该患者患有严重主动脉瓣狭窄，需要进行经导管主动脉瓣植入术（TAVI）。在TAVI的背景下，仅有少数病例报告描述过异常LCX。在一些病例中，LCX未受影响。然而，也有TAVI瓣膜置入后发生闭塞的报道。我们报告了在我们的病例中，在瓣膜置入前的术前影像学检查及操作注意事项，该病例中的LCX未受TAVR瓣膜影响。需要更多的病例报告或系列研究来帮助评估哪些特征与异常LCX梗阻风险增加相关。
