BACKGROUND Woven coronary artery is an extremely rare disease with unknown etiology.This condition is difficult to diagnosis by traditional methods.CASE SUMMARY A 67-year-old male presented to the cardiology department with a history of mild chest pain for 6 mo.Coronary computed-tomography angiography revealed a soft plaque with a 40%stenosis in the right coronary artery(RCA).A linear shadow was seen both on left circumflex(LCX)and RCA.Further coronary angiography showed an 80%regional stenosis in the area proximal of LCX and RCA,and it was divided into different channels with diffuse stenosis.Intravascular ultrasound(IVUS)and optical coherence tomography(OCT)were performed in RCA.These confirmed a woven coronary artery.No stent was implanted.He remained asymptomatic during the 5-year follow-up period.CONCLUSION Woven coronary artery can be distinguished from spontaneous dissection and revascularization of thrombosis.IVUS and OCT are useful in obtaining a definite diagnosis,which decreases chances of unnecessary intervention.
