Kawasaki disease (KD) is an acute systemic vasculitis of unknown etiology that affects children. There are few reports that describe the Epstein-Barr virus (EBV) as the possible infectious agent of KD. Here, we describe a case of KD in a 15- year-old boy complicated with giant coronary artery aneurysms, pericardial effusion, and splenic infarction. The clinical course of KD was... |

Acute rheumatic fever and rheumatic carditis were still important disease of the acquired heart
disease in children and adults, in spite of improving socioeconomic status in Korea. Recently, many
outbreaks of acute rheumatic fever have been reported in the papers from developed countries. We
should be aware of such outbreaks of acute rheumatic fever and should pay attention to their
treatment of the patients... |

PRA’s in peripheral vein, both renal veins, and inferior vena cava (IVC) were measured in 25
normotensive children without renal disease undergoing cardiac catheterization for their underlying
cyanotic congenital heart disease. And we presented the results as reference values/ranges of PRA in
children.
1) There was no significant difference in PRA between both side renal veins at any absolute PRA
levels with a mean ratio (RT/LT)... |

Anomalous origin of one pulmonary artery from the ascending aorta is a rare congenital malformation.
It happens as the result of abnormal development of the 6th aortic arch. Anomalous origin of right pulmnary artery is more frequent than left. It is frequently associated with P.D.A., V.S.D. and T.O.F. In this malformation, congestive heart failure develops in early life and once the... |
