摘要

在接受冠狀動脈電腦斷層血管造影術（Coronary Computed Tomographic Angiography, CCTA）的成年受檢者中，約有0.6%－1.3%的人會發現先天性冠狀動脈異常。雙分支的右冠狀動脈和心肌架橋皆屬冠狀動脈先天性異常。心肌架橋（Myocardial Bridge, MB）發生在左冠狀動脈的機率為90%，遠高於右冠狀動脈的10%，雙分支的右冠狀動脈是罕見的冠狀動脈異常，根據過往文獻指出僅發生過80個案例。本案例為受檢者在接受健康檢查時使用冠狀動脈電腦斷層血管造影術（Coronary Computed Tomographic Angiography, CCTA）檢測出雙分支右冠狀動脈（Split RCA）並在其後側分支發現合併有深部心肌架橋（Myocardial Bridge, MB）的罕見案例。

Congenital coronary artery anomalies are rare with an incidence of 0.6%-1.3% of adult examinees undergoing coronary computed tomography angiography. Both the split coronary artery and myocardial bridge are congenital abnormalities of the coronary artery. A myocardial bridge is mainly confined to the left anterior descending coronary artery in about 90%, which is much higher than occurring in the right coronary artery. To the best of our knowledge, split right coronary artery is a rare coronary artery abnormality and only 80 cases have been reported. In this report, we report a case of split right coronary artery coexist with a deep myocardial bridging in the posterior branch diagnosed on CCTA.
