BACKGROUND The long-term consequences of the cardiovascular sequelae in Kawasaki disease remain uncertain. METHODS AND RESULTS We identified 594 consecutive children with acute Kawasaki disease between 1973 and 1983, and this cohort was followed up for 10 to 21 years (mean, 13.6 years). In all patients, we evaluated coronary lesions by coronary(More)
Using in vivo microdialysis, a comparative study was conducted to examine the effects of amphetamine-related compounds (methamphetamine, MAP; 3,4-methylenedioxymethamphetamine, MDMA; p-methoxyamphetamine, PMA; p-methoxymethamphetamine, PMMA; 4-methylthioamphetamine, 4-MTA; 3,4,5-trimethoxyamphetamine, TMA; 2,5-dimethoxy-4-iodoamphetamine, DOI) on(More)
OBJECTIVE To define by three dimensional echocardiography the pattern and potential determinants of contraction of a secundum atrial septal defect through the cardiac cycle, and to evaluate the possibility of using cross sectional transthoracic and transoesophageal imaging to assess the dynamic nature of the defect. DESIGN Three dimensional(More)
Morphological alterations occasionally found in the myocardium of methamphetamine (MAP) abusers include hypertrophy, atrophy, disarrangement of myofibrils and fibrosis. These cardiac alterations have been thought to be due to an indirect action of MAP via catecholamines released by MAP administration. However, the direct effect of MAP on cardiomyocytes is(More)
To examine the relationship between the plasma levels of angiogenic growth factors and the severity of cyanosis, 80 patients with cyanotic heart disease (CHD) and 81 healthy controls were studied. Median age and mean arterial blood oxygen saturation respectively were 4.2 years and 81% in CHD subjects and 4.8 years and 98% in controls. Vascular endothelial(More)
OBJECTIVES To elucidate the prenatal and postnatal course of fetal congenital atrioventricular block (CAVB) during the past decade in the Japanese population. DESIGN Retrospective multicentre study. All fetuses with CAVB in 10 Japanese institutions in the period from January 1990 to August 2001 were included. PATIENTS Of the 48 fetuses with CAVB, 17 had(More)
BACKGROUND For the clinical management of patients with complex congenital heart disease (CHD), accurate evaluation of their morphologic conditions is critical. Three-dimensional (3D) helical computed tomography (CT) angiography has been used to assess the vascular system in adult patients; the indication for complex CHD, especially in the neonatal period,(More)
BACKGROUND Although most neonates with d-transposition of the great arteries (TGA) have an uncomplicated preoperative course, some with a restrictive foramen ovale (FO), ductus arteriosus (DA) constriction, or pulmonary hypertension may be severely hypoxemic and even die shortly after birth. Our goal was to determine whether prenatal echocardiography can(More)
The importance of managing fetal arrhythmia has increased over the past three decades. Although most fetal arrhythmias are benign, some types cause fetal hydrops and can lead to fetal death. With the aim of improving the outcome in such cases, various studies for prenatal diagnosis and perinatal management have been published. Detailed analysis of the type(More)
UNLABELLED The purpose of this study was to investigate the changes in plasma concentrations of atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP) in patients with atrial septal defect (ASD) during transcatheter closure of defects. The plasma concentrations of ANP and BNP were obtained from 14 patients with ASD at before closure, and at 5(More)
