A 50 year-old female patient was admitted to our outpatient clinic with a two year history of chest pain and dyspnoea on exertion. Echocardiography revealed apical hypokinesia with an ejection fraction of 50% on the left ventricle. Coronary angiography revealed that the left main coronary artery was arising from the right sinus of Valsalva and than coursing posterior to the aorta. There were significant stenoses at the proximal right coronary artery (RCA) and the proximal left anterior descending coronary artery (LAD). The RCA lesion disappeared after intracoronary nitroglycerine administration, and the LAD lesion disappeared the next day when the patient was due to undergo percutaneous intervention. Stress myocardial perfusion scintigraphy revealed anteroseptal ischaemia consistent with reversible ischaemia.
一位 50 岁女性患者因胸痛和劳力性呼吸困难两年，到我院门诊就诊。超声心动图显示左心室心尖部运动减弱，射血分数为 50%。冠状动脉造影显示左主干发自右冠窦，然后走行于主动脉后方。右冠状动脉（RCA）近端和左前降支（LAD）近端有明显狭窄。RCA 病变在冠状动脉内给予硝酸甘油后消失，LAD 病变在第二天行经皮介入治疗时消失。应激心肌灌注闪烁显像显示前间隔缺血，与可逆性缺血一致。
