Inferior Right Ventricular Wall Thickness by Echocardiogram: A Novel Method of Assessing Hypertrophy in Neonates and Infants
An established echocardiographic (echo) standard for assessing the newborn right ventricle (RV) for hypertrophy has not been thoroughly developed. This is partially due to the RV’s complex architecture, which ...

Left Ventricular Mass Quantification by Two-Dimensional Echocardiography in a Pediatric Population: Correlation with Cardiac Magnetic Resonance Imaging
Quantification of left ventricular (LV) mass by echocardiography has not been validated against the gold standard of cardiac magnetic resonance imaging (CMR) in the pediatric population. The purpose of this st...

Blood Pool Segmentation Results in Superior Virtual Cardiac Models than Myocardial Segmentation for 3D Printing
The method of cardiac magnetic resonance (CMR) three-dimensional (3D) image acquisition and post-processing which should be used to create optimal virtual models for 3D printing has not been studied systematic...

Feature Tracking-Derived Peak Systolic Strain Compared to Late Gadolinium Enhancement in Troponin-Positive Myocarditis: A Case–Control Study
Cardiac magnetic resonance (CMR) assesses myocardial involvement in myocarditis (MYO). Current techniques are qualitative, subjective, and prone to interpretation error. Feature tracking (FT) analyzes myocardi...

Application of Virtual Three-Dimensional Models for Simultaneous Visualization of Intracardiac Anatomic Relationships in Double Outlet Right Ventricle
Our goal was to construct three-dimensional (3D) virtual models to allow simultaneous visualization of the ventricles, ventricular septal defect (VSD) and great arteries in patients with complex intracardiac ...

Two-Dimensional Speckle-Tracking-Derived Segmental Peak Systolic Longitudinal Strain Identifies Regional Myocardial Involvement in Patients with Myocarditis and Normal Global Left Ventricular Systolic Function
The presence of myocardial late gadolinium enhancement (LGE) by cardiac magnetic resonance (CMR) imaging in concert with electrocardiography and elevated biomarkers helps support the diagnosis of acute myocard...

Subpulmonary Stenosis Assessed in Midtrimester Fetuses With Tetralogy of Fallot: A Novel Method for Predicting Postnatal Clinical Outcome
This study aimed to determine whether quantification of subpulmonary stenosis (SPS) in tetralogy of Fallot (TOF) in the second-trimester fetus can predict postnatal clinical outcome measured by pulmonary valve...

Comparison Between Proximal Thoracic Vascular Measurements Obtained by Contrast-Enhanced Magnetic Resonance Angiography and by Transthoracic Echocardiography in Infants and Children With Congenital Heart Disease
Accurate assessment of the proximal thoracic vasculature in infants and children with congenital heart disease (CHD) is vital for deciding the appropriate surgical or interventional procedure and predicting ou...

Outcomes of Mitral Regurgitation Associated With Large Ventricular Septal Defect and a Normal Mitral Valve Apparatus: Does Intact Atrial Septum Have an Impact?
The hemodynamics of isolated large ventricular septal defect with an intact atrial septum results in greater mitral valve (MV) annular dilation and an increased incidence of mitral regurgitation (MR). MR will ...
