RATIONALE
Woven coronary artery is an extremely unusual congenital anomaly with unknown etiology. Because of normal flow after anomalous segment, this anomaly is considered to be benign.
PATIENT CONCERNS
A 51-year-old man was admitted to our hospital with exertional dyspnea that he had experienced for half a year. Woven coronary artery was found in coronary angiography.
DIAGNOSES
The patient was diagnosed with mitral regurgitation and woven coronary. Silent myocardial infarction was found in cardiac surgery.
INTERVENTIONS
Coronary artery bypass grafting was performed in the process of cardiac surgery.
OUTCOMES
At 4 weeks follow-up, he was well and without symptoms.

Although most woven coronary arteries are considered to be benign, myocardial ischemia even myocardial infarction can be caused by this anomaly.
理论依据
编织状冠状动脉是一种极其罕见的先天性异常，病因不明。由于异常节段后血流正常，这种异常被认为是良性的。
患者情况
一名51岁男性因半年来的劳力性呼吸困难入院。冠状动脉造影发现编织状冠状动脉。
诊断
患者被诊断为二尖瓣反流和编织状冠状动脉。心脏手术中发现无症状心肌梗死。
干预措施
心脏手术过程中进行了冠状动脉搭桥术。
结果
随访4周时，他情况良好，无症状。
经验教训
尽管大多数编织状冠状动脉被认为是良性的，但这种异常可导致心肌缺血甚至心肌梗死。
