Anomalous coronary arteries are rare and often incidental findings. Most variants are benign. We present the case of a 75-year-old man with exertional dyspnea in whom the left anterior descending coronary artery arose from the right sinus of Valsalva, and the left circumflex coronary artery originated from the distal right coronary artery and supplied the obtuse marginal branch. No arteries originated from the left sinus of Valsalva. The patient was prescribed optimal medical therapy for atherosclerotic stenosis in his ramus intermedius. His symptoms were stable 3 years later.
异常冠状动脉是罕见的,通常是偶然发现的。大多数变异是良性的。我们报告了一例 75 岁男性,劳力性呼吸困难,左前降支发自右冠窦,左回旋支发自右冠状动脉远端并供应钝缘支。无冠状动脉发自左冠窦。患者因中间支粥样硬化狭窄而接受最佳药物治疗。3 年后,他的症状稳定。
