AIM There are discrepancies in the reported prevalence of congenital heart disease (CHD). This study prospectively evaluated the prevalence of CHD in consecutive newborns using echocardiographic screening. METHODS A cohort screening study was conducted in an unselected series of all live-birth newborns. Two-dimensional and colour Doppler echocardiography(More)
BACKGROUND Few studies have investigated the relationship between myocardial tissue Doppler parameters and fetal size adjusted for gestational age and its trend has been controversial. AIMS To investigate fetal cardiac function before birth using tissue Doppler imaging (TDI: indicated by the prime symbol (')) in low-risk term pregnancies by comparing the(More)
This study aimed to evaluate whether an ultrasound-guided technique can improve upon a landmark-guided technique in achieving femoral vein access in pediatric cardiac catheterization. This study examined 87 consecutive subjects with a median age of 2 years (range, 1 month to 19 years) who had congenital or other heart disease. Femoral vein puncture was(More)
OBJECTIVE To evaluate endothelial function in children within 5 years after the onset of Kawasaki disease (KD). STUDY DESIGN A total of 46 children were enrolled prospectively as follows: 9 patients with KD and coronary artery lesions composed group 1, 15 patients with KD but without coronary artery lesions composed group 2, and 22 healthy age- and(More)
BACKGROUND Our goal was to evaluate the serial change in myocardial performance from fetus to neonate using tissue Doppler imaging (TDI). METHOD AND RESULTS There were 37 term infants in the present study. The TDI sensor was placed at the level of the lateral mitral annulus (M-TDI), inter-ventricular septum (IVS-TDI) and the lateral tricuspid annulus(More)
BACKGROUND This study was undertaken to identify factors correlating with plasma levels of B-type natriuretic peptide (BNP) and its N-terminal portion (NTpro BNP) in the acute phase of Kawasaki disease (KD). METHODS This study included 91 patients with KD treated at a hospital affiliated to Hamamatsu University School of Medicine between October 2003 and(More)
BACKGROUND Metabolic syndrome is listed as a risk for atherosclerosis. However, changes in that risk during childhood and adolescence have not been well-documented. It is also unclear whether individuals with abdominal obesity, but with as yet undiagnosed metabolic syndrome, have cardiovascular risks. METHODS AND RESULTS Ninety-two patients were studied(More)
BACKGROUND AND OBJECTIVE Ulinastatin therapy may be an additional therapeutic approach to Kawasaki disease (KD). This study set out to determine whether primary intravenous ulinastatin therapy has more beneficial effects than intravenous immunoglobulin (IVIG) therapy in the acute phase of KD, and whether addition of ulinastatin to IVIG might improve(More)
BACKGROUND The left ventricular (LV) diastolic performance of infants who were in a stable post-treatment condition in the neonatal intensive care unit was evaluated using echocardiography. METHODS AND RESULTS The study group comprised 55 infants (Stable infant group, SI) and the parameters of LV performance were: LV propagation velocity (Vp) by color(More)
PURPOSE The goal of the present study is to carry out prospective echocardiographic measurements of intima-media thickness (IMT) in the abdominal artery of newborns. METHODS Study subjects were 96 mothers and their newborns. We measured the adjusted IMT (aIMT, mm/mm) of newborn abdominal arteries by high-resolution ultrasound and evaluated the association(More)
