Here we report for the first time on the diagnostic potential of cardiovascular magnetic resonance (CMR) to delineate the proximal course of an anomalous left circumflex coronary artery (LCX) originating from the right pulmonary artery in an adult patient with no other form of congenital heart disease. The patient was referred to our institution due to exertional chest discomfort. X-Ray coronary angiography showed a normal left anterior descending coronary artery (LAD) and right coronary artery (RCA), while the LCX was filled retrograde by collateral flow through the LAD and the RCA. The origin of the LCX was postulated to be the pulmonary artery, but the exact origin of the anomalous artery could not be depicted on conventional angiograms. CMR provided the unambiguous depiction of the origin of the anomalous LCX from the right pulmonary artery and the delineation of its proximal course in this case of a very rare coronary anomaly in adults.
在此，我们首次报告了心血管磁共振成像（CMR）在一名无其他先天性心脏病形式的成年患者中，对于描绘起源于右肺动脉的异常左旋支冠状动脉（LCX）近端走行的诊断潜力。该患者因运动时胸部不适转诊至我院。X线冠状动脉造影显示左前降支冠状动脉（LAD）和右冠状动脉（RCA）正常，而LCX通过LAD和RCA的侧支循环逆行显影。推测LCX起源于肺动脉，但常规血管造影无法明确显示异常动脉的确切起源。在这例成人非常罕见的冠状动脉异常病例中，CMR清晰地显示了异常LCX起源于右肺动脉，并描绘了其近端走行。
