Subjects
CALs were observed in 47 patients (12.2%), while transient pericardial
effusion, valve regurgitation, cardiac enlargement, and ventricular
systolic dysfunction were noted in 11, 40, 38, and 2 children,
respectively. No significant difference was found in serum coagulation
profiles between the CALs and non-CALs groups. (Supplemental material
