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.
Lessons:
Although most woven coronary arteries are considered to be benign, myocardial ischemia even myocardial infarction can be caused by this anomaly.
