BACKGROUND: Published nomograms of pediatric echocardiographic measurements are limited by insufficient sample size to assess the effects of age, sex, race, and ethnicity. Variable methodologies have resulted in a wide range of Z scores for a single measurement. This multicenter study sought to determine Z scores for common measurements adjusted for body surface area (BSA) and stratified by age, sex, race, and ethnicity. METHODS AND RESULTS: Data collected from healthy nonobese children ≤18 years of age at 19 centers with a normal echocardiogram included age, sex, race, ethnicity, height, weight, echocardiographic images, and measurements performed at the Core Laboratory...

RATIONALE: High take-off of the coronary arteries is a rare cardiac anatomic anomaly, which may occur independently or with other congenital heart defects. In the clinical setting, it is noteworthy as a cause of sudden cardiac death. Further, it is vital to identify such anomalies to avoid intraoperative catastrophes in surgeries for congenital heart defects. PATIENT CONCERNS: A II/6 systolic heart murmur on physical examination was incidentally found in a 9-year-old boy; he was confirmed to have a secundum-type atrial septal defect on echocardiography...

BACKGROUND: Pediatric Crohn's disease is associated with perianal disease (PAD). Magnetic resonance enterography (MRE) assesses small bowel involvement in pediatric inflammatory bowel disease (PIBD). Pelvic MRI (P-MRI) is the gold standard for assessing PAD. PURPOSE: To determine if MRE can accurately detect PAD in PIBD, distinguishing perianal fistulae (PAF) from perianal abscesses (PAA), referenced against P-MRI. STUDY TYPE: Retrospective...

PURPOSE: The distinction between physiologic (innocent) and pathologic (organic) heart murmurs is not always easy in routine practice, leading too often to unnecessary cardiology referrals and expensive investigations. We aimed to test the hypothesis that the complete disappearance of murmur on standing can exclude cardiac disease in children. METHODS: From January 2014 to January 2015, we prospectively included 194 consecutive children aged 2 to 18 years who were referred for heart murmur evaluation to pediatric cardiologists at 2 French medical centers...

BACKGROUND: Multiple echocardiographic methods are used to measure left ventricular size and function. Clinical management is based on individual evaluations and longitudinal trends. The Pediatric Heart Network VVV study (Ventricular Volume Variability) in pediatric patients with dilated cardiomyopathy has reported reproducibility of several of these measures, and how disease state and number of beats impact their reproducibility. In this study, we investigated the impact of observer and sonographer variation on reproducibility of dimension, area, and volume methods to determine the best method for both individual and sequential evaluations...

Care for patients with cleft lip and palate is best managed by a craniofacial team consisting of a variety of specialists, including surgeons, who are generally plastic surgeons or otolaryngologists trained in the United States. The goal of this study was to compare the surgical approaches and management algorithms of cleft lip, cleft palate, and nasal reconstruction between plastic surgeons and otolaryngologists. We performed a retrospective analysis of the American College of Surgeons' National Surgical Quality Improvement Program Pediatric database between 2012 and 2014 to identify patients undergoing primary repair of cleft lip, cleft palate, and associated rhinoplasty...

BACKGROUND: Pulmonary valve replacement is becoming the most frequent congenital heart surgery performed on adolescents and young adults. Numerous surgical options are available, including autologous pericardium, mechanical valves, allografts, and bioprosthetic valves. Each option has limitations with durability and freedom from reintervention for stenosis or insufficiency, particularly in the pediatric population. The purpose of this study was to analyze our uniquely designed, expanded polytetrafluoroethylene (ePTFE) valved conduit (VC) for right ventricular outflow tract reconstruction...

OBJECTIVE Endoscopic third ventriculostomy with choroid plexus cauterization for the treatment of neonatal and infant hydrocephalus has gained popularity in the past decade. Identifying treatment failure is critically important. Results of a pilot study of 2 novel imaging markers seen on fast-sequence T2-weighted axial MRI showed potential clinical utility. However, the reliability of multiple raters detecting these markers must be established before a multicenter validation study can be performed. METHODS Two sets of de-identified single-shot T2-weighted turbo spin-echo axial images were prepared from scans of patients before and after they underwent endoscopic third ventriculostomy with choroid plexus cauterization between March 2013 and January 2016...

OBJECTIVE: To investigate the clinical usefulness of echocardiography in the diagnosis of infracardiac total anomalous pulmonary venous connection (ITAPVC) in neonates and infants. METHODS: Retrospective analysis on 8 patients with ITAPVC was performed using echocardiography between April 2006 and December 2016. There were 4 boys and 4 girls with a mean age of 79.8 days (ranging from 15 to 195 days). A combined scanning via parasternal, subcostal and apical acoustic windows had been employed to diagnose ITAPVC and to trace the course and site of the anomalous pulmonary venous drainage, and to confirm the direction of the inter-atrial shunt and enlargement of right atrium and right ventricle...

BACKGROUND AND PURPOSE: Synthetic MR imaging is a new technique to create absolute R1 relaxivity (1/T1), R2 relaxivity (1/T2), and proton-density maps using a single multiple-spin-echo saturation recovery sequence. These relaxivity maps allow rapid automated intracranial segmentation of tissue types. To assess its utility in children, we created a normative data base of intracranial volume and brain parenchymal, GM, WM, CSF, and myelin volumes in a pediatric population with normal brain MRI findings using synthetic MR imaging...

BACKGROUND: We previously reported on the short-term impact of an echocardiography "Boot Camp" on a single class of cardiology fellows (CF). The impact of the Boot Camp on performance throughout fellowship is unknown. METHODS: We enrolled four classes of CFs and two classes of cardiac ICU fellows (CVs) prospectively into the Boot Camp and compared CFs to a historical cohort. Experience with echocardiography was surveyed. Outcome measures included written pre- and post-Camp exams, a performance based test (PBT), self-efficacy assessments, numbers of echocardiograms performed, and echocardiogram quality during the last 3 months of fellowship...
