Implications of Changing Z-Score Models for Coronary Artery Dimensions in Kawasaki Disease

Coronary artery abnormalities in Kawasaki disease (KD) are assessed using echocardiographic z-scores. We hypothesized that changing the coronary artery (CA) z-score model would alter diagnosis and management of children with KD.In this retrospective single-center study of children treated for KD (9/2007-1/2020), we collected echocardiographic measurements for the left anterior descending (LAD), right (RCA), and left main (LMCA) coronary arteries...
