BACKGROUND Evidence indicates that corticosteroid therapy might be beneficial for the primary treatment of severe Kawasaki disease. We assessed whether addition of prednisolone to intravenous immunoglobulin with aspirin would reduce the incidence of coronary artery abnormalities in patients with severe Kawasaki disease. METHODS We did a multicentre,(More)
BACKGROUND The major complication of Kawasaki coronary disease is myocardial infarction caused by thrombus formation inside the aneurysm or by organic obstructive lesion following the regression of aneurysm, while the indications for surgical therapy remain controversial. We have adopted coronary artery bypass grafting (CABG) even in young children for(More)
BACKGROUND The aim of this study was to evaluate cardiac function and cardiac reserved function in asymptomatic anthracycline-treated long-time survivors of childhood cancer using dobutamine (DOB) stress echocardiography. METHODS A total of 26 patients (19 males and 7 females) were divided into four groups according to cumulative dose of anthracycline(More)
Kawasaki disease causes coronary artery lesions, such as dilatation, aneurysms, stenosis, and even occlusion in young children, and is one of the most common acquired heart diseases in developed countries. More than 10,000 new cases are reported in Japan every year. In its acute phase, severe coronary arteritis induces morphological changes in coronary(More)
BACKGROUND Local delivery of stromal cell-derived factor-1alpha (SDF-1) has been demonstrated to improve hind limb ischemia through enhanced neovascularization in animals. It was hypothesized that local administration of SDF-1 also contributes to neovascularization of ischemic heart. METHOD Acute myocardial infarction was created by left coronary artery(More)
BACKGROUND Fetal supraventricular tachycardia confers an increased risk of cardiac failure, hydrops, and eventual intrauterine death. Although protocols for prenatal anti-arrhythmic treatment are now well established, few published reports discuss this condition in the setting of multiple pregnancies. CASE REPORT A 20-year-old primigravida woman with a(More)
BACKGROUND We reported previously that intravenous immunoglobulin (IVIG) plus prednisolone for initial therapy for Kawasaki disease (KD) prevented coronary artery abnormalities (CAA) more effectively than IVIG alone. However, questions remain as to whether PSL has potential benefit in all KD patients. The present study was designed to explore the(More)
The Child Coronary Arterial Diameter Reference Study Group of the Japan Kawasaki Disease Society recommends ultrasound imaging as the standard method for measuring the diameter of the coronary artery in children. The patient is examined in a supine or right decubitus position by using a sector probe (≥ 5 MHz). The coronary arterial diameter measured at the(More)
OBJECTIVES We used myocardial fractional flow reserve (FFR(myo)) and coronary flow reserve (CFR) to estimate cut-off values for assessment of the functional severity of coronary stenosis and myocardial ischemia, and we tested the usefulness of coronary blood hemodynamic measurements before and after plain old balloon angioplasty (POBA) and coronary artery(More)
AIMS We evaluated the systolic and diastolic functions of both ventricles from the early neonatal period to adolescence using color tissue Doppler imaging and 2-dimensional tissue tracking echocardiography. METHODS We examined 100 healthy children (aged 1-5 days, n = 20; 1 month, n = 20; 1 year, n = 20; 6-7 years, n = 20; and 12-13 years, n = 20). Blood(More)
