Dobutamine (DOB) stress radionuclide ventriculography (RVG) is proposed for evaluating left ventricular performance in patients with Kawasaki disease (KD). Dobutamine stress RVG, up to 15 microg x kg(-1) x min(-1), was performed in 40 patients with a history of KD, some of whom had a perfusion defect (PD group) on dipyridamole stress thallium-201 myocardial(More)
OBJECTIVES This study investigated patients with acute Kawasaki disease (KD) to validate myeloid-related protein (MRP)-8/MRP-14 as a marker of disease activity and severity of coronary artery lesion development. BACKGROUND Both MRP-8 and -14, which are S100-proteins secreted by activated neutrophils and monocytes, bind specifically to endothelial cells(More)
Nitric oxide (NO) serves many vasoprotective roles, but the massive release of NO causes arterial wall degeneration. We investigated whether enhanced nitric oxide synthase (iNOS) expression in peripheral blood leukocytes and circulating endothelial cells mirrors the progression of coronary arterial lesions in 55 children with acute Kawasaki disease (KD),(More)
Neutrophil-derived S100A12 is strongly upregulated during the acute stage of Kawasaki disease and decreases significantly in response to intravenous immune globulin (IVIG) treatment, whereas in nonresponders, serum concentrations increases after initial treatment. Decreased S100A12 expression in neutrophils was detected initially in nonresponders but(More)
It is not always easy to observe and screen atrial septal defects (ASD) using echocardiography. In addition, there are no established echocardiographic reference indices for screening patients with ASDs. We retrospectively reviewed our database and recruited 151 isolated ASD patients and 2769 healthy subjects. In total, 307 echocardiographic studies were(More)
The purpose of this study was to assess the capability of multiplanar cine magnetic resonance imaging (MRI) for evaluating pre- and post-operative pulmonary circulation in patients with pulmonary atresia and severe pulmonary stenosis. Seventy-three multiplanar cine MRIs were performed in 30 patients, aged 1 month to 7 years (mean age, 27 months). The(More)
This study was undertaken to evaluate the feasibility of ultrafast computed tomography (CT) and magnetic resonance imaging (MRI) for anatomical and pathophysiological diagnosis of isolated noncompaction of the left ventricular myocardium (INVM) compared with other imaging modalities including thallium myocardial imaging. Six patients, three sets of(More)
BACKGROUND Clinically useful indices of fetal cardiac function have not been fully delineated for tissue Doppler imaging (TDI). METHODS AND RESULTS In the present study, 56 pregnancies between the 17(th) and 38(th) weeks of gestation included 38 normal fetuses, 6 cases of hydrops fetalis (HF), and 12 of intrauterine growth retardation (IUGR). Peak(More)
A male infant presenting with severe heart failure and respiratory distress was diagnosed with a hypoplastic right lung, scimitar syndrome with pulmonary sequestration and multiple anomalous systemic arteries, left bronchomalacia, a large atrial septal defect and coarctation of the aorta. The infant underwent a successful combined treatment of surgical and(More)
BACKGROUND Many studies have investigated tricuspid annular plane systolic excursion (TAPSE) as a longitudinal right ventricular (RV) contraction. The aim of this study was to clarify the mechanism of RV systolic function compared with longitudinal and radial RV contractions in healthy children. METHODS AND RESULTS A total of 815 consecutive healthy(More)
