Woven right and aneurysmatic left coronary artery associated with Kawasaki disease in a 9-month-old patient

Abstract

Woven coronary artery disease is an extremely rare congenital abnormality with unusual findings of branching thin channels and distal reanastomosis. This pathologic finding was reported earlier in a few adult patients. In Kawasaki disease, coronary arterial system is commonly affected, which causes a necessity of cardiac imaging. We report a 9-month-old infant with Kawasaki disease in which left coronary artery aneurysm and woven right coronary artery were coincidentally detected during coronary angiography. After 1 year, coronary angiogram was re-performed and showed no changes in the coronary arteries. During the follow-up period of 4 years, the patient remained asymptomatic. In Kawasaki disease, there is a tendency for thrombus formation and a woven coronary artery can be easily misinterpreted as a thrombus. Woven coronary artery is a benign condition and it should not be confused with a thrombus or a stenosis related finding which needs a medical or surgical intervention.
