The anomalous aortic origin of the right coronary artery with an intramural course is rare and can cause myocardial ischemia, for which surgical repair is indicated. We present the case of a 49-year-old man with this anomaly whose preoperative myocardial perfusion positron emission tomography revealed inducible ischemia. Comparison of the preoperative and follow-up (6 months) positron emission tomography findings showed significant improvement in regional myocardial flow reserve and relative flow reserve, in keeping with the improvement in symptoms. However, positron emission tomography/myocardial perfusion imaging findings were difficult to interpret.
右冠状动脉发自主动脉异常且走行于壁内的情况较为罕见，可导致心肌缺血，对此需行手术修复。我们报告了1例患有这种异常的49岁男性病例，其术前心肌灌注正电子发射断层扫描显示有诱发性缺血。术前和随访（6个月）正电子发射断层扫描结果比较显示，局部心肌血流储备和相对血流储备有显著改善，与症状改善相符。然而，正电子发射断层扫描/心肌灌注成像结果难以解读。
