Evaluation of coronary artery lesions in children with Kawasaki disease by coronary angiography

In children with high-risk KD-CAL, invasive coronary angiography (CAG) is a safe and feasible procedure that provides superior anatomical detail for detecting critical complications such as stenosis and thrombosis. Echo-cardiography remains the first-line modality for aneurysm sizing and serial monitoring. However, for comprehensive coronary assessment following echocardiography, CT coronary angiography (CTCA) is the preferred non-invasive imaging standard. Invasive CAG should be reserved for selected high-risk or complex cases where it provides decisive anatomical and functional information to guide definitive management.
