title: Usefulness of Tc-99m HMPAO-labeled WBC heart scan to predict impaired ventricular function and coronary artery dilation in children with Kawasaki disease.
abstract: Forty-nine children with Kawasaki disease were included in this study. Based on the severity of carditis as determined by Tc-99m HMPAO-labeled WBC heart scan, the children were separated into two groups. Group A (n=24) had significant carditis and group B (n=25) did not have significant carditis. The left and right ventricular ejection fractions (LVEF and RVEF) were evaluated by equilibrium multigated blood pooling ventriculography. Diameters of the left and right coronary arteries (LCA and RCA) were measured by two-dimensional echocardiography. The results showed that group A had lower LVEF and RVEF, but larger diameters of the LCA and RCA than those of group B patients. The sensitivity of significant carditis to predict left ventricular dysfunction, right ventricular dysfunction, LCA dilation and RCA dilation was 88.9, 70.6, 75, and 71.4%, respectively; the specificities were 100, 100, 100, and 67.9%, respectively. Our findings suggest that significant carditis determined by Tc-99m HMPAO-labeled WBC heart scan can accurately predict impaired ventricular function and coronary artery dilation.
