BACKGROUND
Abnormal separation of right coronary artery (RCA) from the left coronary system is an extremely rare variation among coronary artery anomalies. The compressions on the anomalous route of this artery may lead to arrhythmia, chest pain, or left ventricular dysfunction or may enhance formation of atherosclerotic plaques.
CASE REPORT
Here, we have reported a patient presented with heart failure who had an anomalous atherosclerotic RCA originating from left anterior descending artery. Interestingly, neither the anomalous origin nor the atherosclerosis was the cause of the patient's problems and she suffered from a hypertensive cardiomyopathy.
CONCLUSION
This reminds that encountering an anomaly should not solely be interpreted as the cause of cardiac disease.
背景
右冠状动脉（RCA）与左冠状动脉系统异常分离是冠状动脉异常中极为罕见的变异。该动脉异常走行处的压迫可能导致心律失常、胸痛或左心室功能障碍，或可能促进动脉粥样硬化斑块的形成。
病例报告
在此，我们报告了一名因心力衰竭就诊的患者，其右冠状动脉异常且有动脉粥样硬化，起源于左前降支动脉。有趣的是，异常起源和动脉粥样硬化均不是该患者问题的原因，她患有高血压性心肌病。
结论
这提醒我们，遇到异常情况不应仅仅将其解释为心脏病的病因。
