Sarcomere gene variants did not improve cardiac function in pediatric patients with dilated cardiomyopathy from Japanese cohorts.

Dilated cardiomyopathy (DCM) is a progressive myocardial disorder characterized by impaired cardiac contraction and ventricular dilation. However, some patients with DCM improve when experiencing left ventricular reverse remodeling (LVRR). Currently, the detailed association between genotypes and clinical outcomes, including LVRR, particularly among children, remains uncertain.

Genetic dilated cardiomyopathy with inflammation in an infant that responded to immunosuppressive therapy evaluated using cardiovascular magnetic resonance.

Cardiovascular magnetic resonance T1 and T2 mapping reflects inflammation, fibrosis, and myocardial oedema. However, its application in infants remains uncertain. Herein, we report a three-month-old boy with dilated cardiomyopathy successfully treated with steroids.

Fusion imaging of single-photon emission computed tomography and magnetic resonance lymphangiography for post-Fontan chylothorax.

A preschool male patient with an extensive cardiac surgical history developed refractory chylothorax after a total cavopulmonary connection. Neither lymphoscintigraphy nor single-photon emission computed tomography (SPECT)/computed tomography could identify the lymphatic system leakage sites. Non-contrast heavy T2-weighted magnetic resonance lymphangiography (MRL) was performed to visualize the lymphatic system.

Thrombus calcification after removing peripherally inserted central catheters in extremely preterm infants.

Pericatheter thrombus calcification is a complication that arises due to central venous catheter insertion and is particularly rare in peripherally inserted central catheters (PICCs). In this case report, we reviewed the clinical course of two neonates experiencing thrombus calcification. The first case involved a male neonate weighing 445 g.

A rare association of left pulmonary artery sling with right pulmonary hypoplasia and total anomalous pulmonary venous connection.

We present the second reported case of left pulmonary artery sling with dextrocardia, right pulmonary hypoplasia, and total pulmonary venous connection in a fetus. This case highlights the importance of the determination of pulmonary artery arrangement by fetal echocardiography if right pulmonary hypoplasia and/or congenital heart disease is suspected.

Prenatal Diagnosis of Criss-Cross Heart Using 4-Dimensional Color Doppler Rendering.

Criss-cross heart is a rare congenital cardiac anomaly characterized by the crossing of two ventricular inflow streams. We have demonstrated the utility of 4-dimensional color Doppler rendering in diagnosing the criss-cross heart in a fetus. Four-dimensional color Doppler rendering can demonstrate the relative direction of intracardiac blood flows and facilitate recognition of the crossover of inflow streams in the same plane, confirming the criss-cross heart diagnosis in the fetus.

Serial echocardiography for immune-mediated heart disease in the fetus: results of a risk-based prospective surveillance strategy.

Objective: Mothers carrying anti-Ro antibodies are frequently referred for weekly echocardiograms to early detect and treat antibody-mediated fetal heart disease. We tested a surveillance strategy based on anti-Ro antibody titers.

Methods: From 2009 to 2014, 232 pregnancies were referred for maternal anti-Ro antibodies.

Impact and issues of detecting fetal congenital heart defects in Kyushu, Japan.

Aim: To determine the current status of fetal CHD screening in our region and to establish a CHD screening system in Japan.

Material And Methods: Subjects were 168 fetuses prenatally-diagnosed with CHD at four referral centers in Japan from 2003 to 2007. Subjects were divided into two groups: group A (n = 84) included cases without extracardiac sonographic abnormalities and known risk factors for CHD and group B (n = 84) included those with extracardiac sonographic abnormalities or risk factors.
