The anomalous origin of the right coronary artery (RCA) as a branch of the left anterior descending (LAD) artery is a very rare variation of single coronary artery. We have reported three cases in the last 10 years. Among 15,000 coronary angiograms, at least 40 cases have been described previously in the literature. The vast majority of previous reports have described a single anomalous vessel with its origin after the first septal perforator of the LAD. Two of our patients presented with acute coronary syndrome and were found to have three vessel disease and left main. They underwent coronary artery bypass graft surgery (CABG) and third case presented with tachycardia had only mild coronary artery disease (CAD) and was treated medically.
右冠状动脉(RCA)起源异常,作为左前降支(LAD)动脉的一个分支,是一种非常罕见的单支冠状动脉变异。在过去10年里我们报告了3例。在15000例冠状动脉造影中,此前文献中至少已描述过40例。之前绝大多数报告描述的是单一异常血管,其起源于LAD的第一间隔穿支之后。我们的两名患者表现为急性冠状动脉综合征,发现有三支血管病变和左主干病变。他们接受了冠状动脉旁路移植术(CABG),第三例表现为心动过速的患者只有轻度冠状动脉疾病(CAD),接受了药物治疗。
