We describe the case of a patient with limiting angina pectoris and anomalous origin of the left coronary artery from the right coronary artery, with a retroaortic course. Myocardial ischemia in the left anterior descending territory was documented by positron emission tomography, confirmed by fractional flow reserve, and relieved by surgical coronary reimplantation. This patient did not have coronary atherosclerosis or any other significant anatomic abnormality, such as myocardial bridging or compression between the aorta and the pulmonary artery. We attempt to describe the mechanisms of myocardial ischemia that contributed to the clinical manifestations in our patient.
我们描述了一例患有局限性心绞痛和左冠状动脉异常起源于右冠状动脉并伴有主动脉后走行的患者。正电子发射断层扫描证实了左前降支区域的心肌缺血，且其血流储备分数也证实了这一点，手术冠状动脉再植入术缓解了这种缺血。该患者没有冠状动脉粥样硬化或任何其他明显的解剖异常，如心肌桥或主动脉与肺动脉之间的压迫。我们试图描述导致该患者临床表现的心肌缺血机制。
