Clinical factors associated with microstructural connectome related brain dysmaturation in term neonates with congenital heart disease.

Objective: Term congenital heart disease (CHD) neonates display abnormalities of brain structure and maturation, which are possibly related to underlying patient factors, abnormal physiology and perioperative insults. Our primary goal was to delineate associations between clinical factors and postnatal brain microstructure in term CHD neonates using diffusion tensor imaging (DTI) magnetic resonance (MR) acquisition combined with complementary data-driven connectome and seed-based tractography quantitative analyses. Our secondary goal was to delineate associations between mild dysplastic structural brain abnormalities and connectome and seed-base tractography quantitative analyses.

Evaluation of cardiac function in the recipient twin in successfully treated twin-to-twin transfusion syndrome using a novel fetal speckle-tracking analysis.

Introduction: This study was designed to evaluate ventricular size, shape, and function in recipient twins following laser therapy for twin-twin transfusion syndrome (TTTS), using novel speckle-tracking techniques.

Methods: This retrospective study enrolled patients that underwent fetal laser surgery for TTTS and had fetal echocardiograms (FE) performed pre- and post-operatively (op), with adequate resolution in the 4-chamber view for analysis, using a speckle-tracking software, to compute the size, shape, and function of both the right (RV) and left (LV) ventricles. Values were indexed to published normal values.

Clinical Factors Associated with Cerebral Metabolism in Term Neonates with Congenital Heart Disease.

Objective: To determine associations between patient and clinical factors with postnatal brain metabolism in term neonates with congenital heart disease (CHD) via the use of quantitative magnetic resonance spectroscopy.

Study Design: Neonates with CHD were enrolled prospectively to undergo pre- and postoperative 3T brain magnetic resonance imaging. Short-echo single-voxel magnetic resonance spectroscopy of parietal white matter was used to quantify metabolites related to brain maturation (n-acetyl aspartate, choline, myo- inositol), neurotransmitters (glutamate and gamma-aminobutyric acid), energy metabolism (glutamine, citrate, glucose, and phosphocreatine), and injury/apoptosis (lactate and lipids).

Provision of Transition Education and Referral Patterns from Pediatric Cardiology to Adult Cardiac Care.

ACC/AHA guidelines recommend a structured preparation for and transfer to adult-oriented cardiac care for adult survivors of pediatric onset heart disease (POHD). Given this, we sought to describe the transition and transfer practices for a cohort of young adults with POHD and to determine factors associated with successful transfer to adult-oriented cardiac care. We performed a single-center, retrospective chart review on patients ≥18 years of age, with POHD likely to require lifelong cardiac care, who were seen in outpatient pediatric cardiology (PC) between 2008 and 2011.

Do pediatric electrophysiologists read pre-participation screening electrocardiograms more accurately than general pediatric cardiologists?

Pre-participation electrocardiogram (ECG) screening of athletes is controversial. Pediatric electrophysiologists do not interpret screening ECGs more accurately than pediatric cardiologists with average number of correct ECG interpretations of 13.1-12.
