Woven coronary artery is a very rare congenital anomaly which may lead to acute coronary syndrome in previous literatures. At present, there is no consensus on the treatment of this coronary artery abnormality.
A 48-year-old male was admitted to the other hospital because of persistent chest pain. The electrocardiogram showed an ST-segment elevation in the v1-v5 lead and the patient was diagnosed with acute anterior myocardial infarction. Coronary angiography revealed 2 lumens in the proximal segment of the left anterior descending artery. Then the patient was transferred to our hospital for further diagnosis and treatment.
The patient was diagnosed with acute myocardial infarction and woven coronary. Transthoracic echocardiography showed left ventricular anterior wall segmental motor abnormalities.
Optical coherence tomography (OCT) and fractional flow reserve (FFR) guided percutaneous coronary intervention was performed successfully.
During the follow-up period of 4 years, the patient remained asymptomatic and no adverse events.
Although the significance of blood flow limitation in one of the lumens detected by FFR is unclear, this strategy of OCT and FFR-guided treatment in woven coronary artery combined with acute coronary events still shows its feasibility.
