Fig 1 (A) Preoperative coronary angiogram with evidence of the abnormal origin of the left circumflex artery (B) Postoperative coronary angiogram with occlusion of the left circumflex artery (black arrow). White arrows indicate the anterolateral (Ac) and posteromedial (Pc) commissure of the mitral valve.

Fig 2 (A) Schematic representation of the retroaortic trajectory of the left circumflex artery. (B) Postoperative computed tomographic scan with evidence of the patent proximal left circumflex artery (white arrow) and its vicinity with the anterolateral (Ac) and posteromedial (Pc) commissure of the mitral valve (grey arrows). (CCA = circumflex coronary artery; LM = left main artery; M = mitral valve; T = tricuspid valve; PDA = posterior descending artery; PT = pulmonary trunk; RCA = right coronary artery.)
