Two-dimensional tissue tracking makes it possible to detect myocardial strain in any direction. Consequently, this method is applicable for evaluation of myocardial dyssynchrony. This study enrolled 22 healthy volunteers (11 boys and 11 girls) ages 1.6 to 10.8 years (mean, 6.8 years). Echocardiography (subxiphoid right anterior oblique view) of the right(More)
We report a case of an immunodeficient 4-year-old boy with acute encephalopathy possibly related to human astrovirus-MLB1 infection. The astrovirus-MLB1 genome was identified in his stool, serum, cerebrospinal fluid, urine, and throat swabs by next generation sequencing. We present additional evidence showing human astroviruses are important infectious(More)
Multidetector-row computed tomography (MDCT) of the heart is a new diagnostic approach for the quantitative evaluation of the coronary artery in adults. However, in children, the quantitative analysis of each cardiac chamber has not been established. We attempt to clarify the feasibility and validation of ECG-gated MDCT as a quantitative diagnostic tool to(More)
Background. The purpose of this study was to evaluate the surgical outcomes and pulmonary artery (PA) development associated with a new strategy wherein the modified Norwood (N) procedure is performed at 1-2 months after bilateral pulmonary artery banding (PAB). Methods. Between January 2008 and February 2010, 16 patients underwent Norwood-type operation(More)
A 13-year-old boy who suffered from Kawasaki disease at the age of 2 months underwent percutaneous transluminal coronary rotational ablation for coronary stenosis. After this procedure, coronary spasm occurred and he experienced acute myocardial infarction within 10 days. Total occlusion of the LAD was demonstrated by coronary angiography. Coronary spasm(More)
BACKGROUND Staphylococcus lugdunensis (S. lugdunensis) is known as a common cause of clinically significant infections in adults although the clinical importance of S. lugdunensis isolates from pediatric samples is less known. The aim of this study is to assess the incidence, characteristics, and outcomes of S. lugdunensis bacteremia (SLB) in children. (More)
