A new diagnostic method for woven coronary artery Optical coherence tomography

Woven coronary artery is an extremely rare and not clearly defined congenital malformation in which the epicardial coronary artery is divided into multiple thin channels. These multiple channels merge again into a normal conduit. This anomaly is a benign condition because there is normal blood flow after the anomalous segment of the abnormal coronary artery. We describe a woven coronary artery anomaly in the left anterior descending artery (LAD) and its first diagonal (DI) branch causing myocardial infarction that was confused with coronary dissection. The definitive diagnosis was made by optical coherence tomography (OCT). Although woven coronary is a benign anomaly, it may cause myocardial infarction. We used the novel method of OCT for the definitive diagnosis and appropriate treatment of this anomaly.
