BACKGROUND: Left ventricular noncompaction (LVNC) can occur in isolation or can co-occur with a cardiomyopathy phenotype or cardiovascular malformation. The yield of cardiomyopathy gene panel testing in infants, children, and adolescents with a diagnosis of LVNC is unknown. By characterizing a pediatric population with LVNC, we sought to determine the yield of cardiomyopathy gene panel testing, distinguish the yield of testing for LVNC with or without co-occurring cardiac findings, and define additional factors influencing genetic testing yield...

Mastering the technical skills required to perform pediatric cardiac valve surgery is challenging in part due to limited opportunity for practice. Transformation of 3D echocardiographic (echo) images of congenitally abnormal heart valves to realistic physical models could allow patient-specific simulation of surgical valve repair. We compared materials, processes, and costs for 3D printing and molding of patient-specific models for visualization and surgical simulation of congenitally abnormal heart valves...

BACKGROUND: Children with obesity have hypertrophic cardiac remodeling. Hypertension is common in pediatric obesity, and may independently contribute to hypertrophy. We hypothesized that both the degree of obesity and ambulatory blood pressure (ABP) would independently associate with measures of hypertrophic cardiac remodeling in children. METHODS: Children, aged 8-17 years, prospectively underwent cardiovascular magnetic resonance (CMR) and ABP monitoring. Left ventricular (LV) mass indexed to height(2...

Neurologic complications can occur with extracorporeal membrane oxygenation (ECMO) due to several factors. Prior studies identified neonates as having unique risk factors and neuroimaging findings post ECMO. The aim of this study is to describe brain magnetic resonance imaging findings of pediatric patients treated with ECMO. We conducted a retrospective study of nonneonatal pediatric patients who underwent a comprehensive brain magnetic resonance imaging after ECMO between January 2000 and July 2015. We identified 47 pediatric patients in the study cohort with a median age of 8 months (interquartile range 3-170 months) and a median ECMO run duration of 7...

PURPOSE OF REVIEW: The purpose of this review is to describe the challenges associated with the diagnosis and treatment of children with borderline ventricles. A borderline ventricle is one in which there is concern that it will not be able to support its circulation. If a biventricular repair is attempted and fails, outcome is often poor. Thus, this early decision is important. RECENT FINDINGS: For the borderline right ventricle, options to add an additional source of pulmonary blood flow make the surgical strategy a bit more flexible than for patients with a borderline left ventricle...

The intubation of conventional transesophageal echocardiography (TEE) probes into patients causes serious esophagus irritation, and thus the use of TEE probes in pediatric practice is limited. In this study, we aimed at the development of a special probe which could be inserted through the nasopharyngeal cavity into the esophagus to obtain the same high-quality echocardiography images as those obtained by conventional TEE and improve patients' experience. During the examination, the patients felt relaxed for a longer time and cooperated with the sonographers in the process of cardiac catheterization conducted in the surgery room or the intensive care unit (ICU), resulting in improved accuracy of the diagnosis and timely administration of appropriate treatment...

REVIEW
Seong-Ho Kim
During the last 10 years, there have been major technological achievements in pediatric interventional cardiology. In addition, there have been several advances in cardiac imaging, especially in 3-dimensional imaging of echocardiography, computed tomography, magnetic resonance imaging, and cineangiography. Therefore, more types of congenital heart diseases can be treated in the cardiac catheter laboratory today than ever before. Furthermore, lesions previously considered resistant to interventional therapies can now be managed with high success rates...

To explore the accuracy of main pulmonary artery (MPA) and ascending aorta (AAO) image evaluation in pediatric patients with single ventricle (SV) by comparing dual-source computed tomography (DSCT) with echocardiography. Thirty-one children with SV were retrospectively enrolled. The stenosis, dilation, and location of MPA and AAO were independently evaluated by DSCT and echocardiography. The accompanying arterial malformations were also assessed by DSCT. For 17 patients undergoing cardiac catheterization, the DSCT-based diameters of MPA and AAO were correlated with their pressures as measured by catheterization...

BACKGROUND: Several studies have reported the accuracy and reproducibility of HeartModel for automated determination of three-dimensional echocardiography (3DE)-derived left heart volumes and left ventricular (LV) ejection fraction (LVEF) in adult patients. However, it remains unclear whether this automated adaptive analytics algorithm, derived from a 'training' population, can encompass adequate echo images in Chinese adolescents. OBJECTIVES: The aim of our study was to explore the accuracy of HeartModel in adolescents compared with expert manual three-dimensional (3D) echocardiography...

Right ventricular (RV) failure is a significant cause of morbidity and mortality in patients with pulmonary hypertension (PH). Myocardial performance index measured by tissue Doppler imaging (TDI-MPI) has been useful in assessing RV dysfunction in adults with PH. However, TDI-MPI as a marker for RV dysfunction or disease severity has not been evaluated in pediatric PH. The aim of this study was to investigate TDI-MPI and correlate with invasive hemodynamics in pediatric PH patients. Eighty pediatric PH patients undergoing cardiac catheterization and simultaneous transthoracic echocardiography were analyzed...

Bicuspid aortic valve (BAV) is the most common type of congenital heart defect (CHD) and is associated with clinically significant cardiovascular complications including valve calcification and ascending aortopathy (AscAo), predominantly occurring in adulthood. While a limited number of genetic etiologies for BAV have been defined, family members of affected individuals display BAV along with other left-sided CHD. This has led to guidelines from the American Heart Association and American College of Cardiology that recommend echocardiographic screening of first-degree relatives of affected adults...

Intravascular ultrasound (IVUS) has been routinely used in some centers to investigate cardiac allograft vasculopathy in pediatric heart transplant recipients. We present an alternative method using more sophisticated imaging software. This study presents a comparison of this method with an established standard method. All patients who had IVUS performed in 2014 were retrospectively evaluated. The standard technique consisted of analysis of 10 operator-selected segments along the vessel. Each study was re-evaluated using a longitudinal technique, taken at every third cardiac cycle, along the entire vessel...
