Image characteristics of woven coronary artery on intravascular ultrasound and optical coherence tomography

Objective To investigate the image characteristics of woven coronary artery(WCA)on intravascular ultrasound(IVUS)and optical coherence tomography(OCT).Methods Thirty-seven patients suspected of WCA on coronary angiography were enrolled from Teaching Hospital of Chengdu University of Traditional Chinese Medcine,Zhengzhou Cardiovascular Disease Hospital and Zhongshan Hospital of Fudan University from January 2013 to July 2020.The intraluminal imaging features of WCA were analyzed using IVUS and OCT.Results Of the 37 patients admitted at the cardiology service,9 patients had WCA.All the patients underwent coronary angiography,IVUS and OCT,of which 6 lesions were located on the right coronary artery,2 lesions were located on the left anterior descending artery and 1 patient had WCA on the circumflex artery.The mean length of WCA lesions was 2.2 cm(ranged from 1.2 cm to 4.5 cm).The angiographic appearance of WCA was numerous small tortious channels origined form the main lumen.The channels appeared to be"doughnut"like pattern and they merged to normal artery again after the anomalous segment.Flow limitation was rare unless there was coronary atherosclerosis.OCT and IVUS showed multiple spiral channels in the anomalous segment,which were independent of each other and each channels had a relatively complete three-layers vascular structure.Conclusions With typical image characteristics,IVUS and OCT are able to screen out WCA and guide the treatment decision making.
