Congenital coronary artery anomalies are present at birth, but most anomalies are discovered as incidental findings during coronary angiography or at autopsy. Double right coronary artery (RCA) is a rare coronary anomaly. Double RCA with bifurcation stenosis in association with degenerative complete heart block (CHB) have never been reported in literature to the best of our knowledge. We therefore report an interesting case of a patient with double RCA and degenerative CHB.
先天性冠状动脉异常在出生时就已存在，但大多数异常是在冠状动脉造影或尸检时作为偶然发现被检测到的。双右冠状动脉（RCA）是一种罕见的冠状动脉异常。据我们所知，双RCA合并分叉狭窄并伴有退行性完全性心脏传导阻滞（CHB）的情况在文献中尚未见报道。因此，我们报告了一例双RCA合并退行性CHB的有趣病例。
