OBJECTIVE: To compare the use of simulator-based and patient-based obstetric ultrasound training. METHODS: This was a prospective, randomized, single-blinded trial. Eighteen consenting obstetric trainees with minimal previous ultrasound exposure were recruited. Enrolled patients were also fully consenting. Mid-trimester fetal brain anatomy in the standard planes (i.e., biparietal diameter and head circumference, cavum septum pellucidum, posterior fossa, and lateral ventricle) was chosen as a surrogate for all fetal anatomy ultrasound training...

OBJECTIVES: To validate a method for performing myocardial segmentation based on coronary anatomy using coronary CT angiography (CCTA). METHODS: Coronary artery-based myocardial segmentation (CAMS) was developed for use with CCTA. To validate and compare this method with the conventional American Heart Association (AHA) classification, a single coronary occlusion model was prepared and validated using six pigs. The unstained occluded coronary territories of the specimens and corresponding arterial territories from CAMS and AHA segmentations were compared using slice-by-slice matching and 100 virtual myocardial columns...

There is evidence to suggest that patients undergoing a Norwood for non-HLHS anatomy may have lower mortality than classic HLHS, but differences in neurodevelopmental outcome have not been assessed. Our objective was to compare survival and neurodevelopmental outcome during the same surgical era in a large, well-described cohort. All subjects who underwent a Norwood-Sano operation between 2005 and 2014 were included. Follow-up clinical, neurological, and developmental data were obtained from the Western Canadian Complex Pediatric Therapies Follow-up Program database...

Ascites is a multi-faceted disease commonly observed in fast growing broilers, which is initiated when the body is insufficiently oxygenated. A series of events follow, including an increase in pulmonary artery pressure, right ventricle hypertrophy, and accumulation of fluid in the abdominal cavity and pericardium. Advances in management practices along with improved selection programs have decreased ascites incidence in modern broilers. However, ascites syndrome remains an economically important disease throughout the world, causing estimated losses of $100 million per year...

PURPOSE: Congenitally corrected transposition of the great arteries (CC-TGA) is a complex form of congenital heart defect with numerous anatomic subgroups. The majority of patients with CC-TGA are excellent candidates for a double-switch procedure. However, in the absence of an unrestrictive ventricular septal defect or subpulmonary stenosis, the left ventricle (LV) may undergo involution and require retraining prior to double switch. The purpose of this study was to review our experience with patients having CC-TGA who required LV retraining prior to a double-switch procedure...

OBJECTIVES: In 2 subtypes of functional single ventricle, double inlet left ventricle (DILV) and tricuspid atresia with transposed great arteries (TA-TGA), systemic output passes through an outflow chamber before entering the aorta. Intracardiac obstruction to this pathway causing systemic outflow tract obstruction (SOTO) may be present at birth or develop over time. Long-term survival after Fontan has not been defined. We defined outcomes utilizing records from 2 centres that were cross-checked with data from a bi-national Fontan Registry for completeness and accuracy...

The correlation between hydrocephalus and Chiari type I malformation (CIM) has been debated since Chiari's first descriptions of CIM but some studies have shown that CIM and hydrocephalus (HCP) could cause symptoms/disease of each other or vice versa. Recent research has found that treatment focused on hydrocephalus with ventricle enlargement also provides alleviation of CIM and even of syringomyelia. However, the lack of consensus among previous studies left unanswered the question of how endoscopic third ventriculostomy (ETV) addresses CIM and why it fails...

Pulmonary arterial hypertension (PAH) occurs when remodeling of pulmonary vessels leads to increased pulmonary vascular resistance resulting in increased pulmonary arterial pressure. Increased pulmonary arterial pressure results in right ventricle hypertrophy and eventually heart failure. Oxidative stress has been implicated in the pathogenesis of PAH and may play a role in the regulation of cellular signaling involved in cardiac response to pressure overload. Secoisolariciresinol diglucoside (SDG), a component from flaxseed, has been shown to reduce cardiac oxidative stress in various pathophysiological conditions...

Heart failure (HF) is a predictable outcome of nearly all cardiovascular diseases including congenital heart diseases (CHD). A special category comprises patients with functional single ventricle (FSV) of the heart because of extreme diversity of anatomical changes of the heart and great vessels, complex mechanisms of development of HF, multistage surgical correction of the defect, presence of arrhythmias, progressive rise of pulmonary vascular resistance, etc. Prevention and treatment of HF in patients with FSV includes surgical optimization of pulmonary blood flow during neonatal period, timely staged surgical correction of the defect, pharmacotherapy, cardiac resynchronization therapy, and in severe cases mechanical cardiac support and heart transplantation...

Purpose/aim: Pulmonary arterial hypertension (PAH) is a lethal disease associated with pulmonary vascular remodeling as well as inflammation. As a kind of tachykinin secreted by nerves and inflammatory cells, substance P (SP) has been proved to be involved in the progression of PAH. Capsaicin can deplete substance P and provide benefits in PAH. However, the mechanism is still unclear. In this article, we aim to illustrate the possible mechanism involved in the process of capsaicin alleviating PAH. MATERIALS AND METHODS: A single injection of monocrotaline (MCT) to male Sprague-Dawley (SD) rats was conducted to induce PAH...

Among the most significant factors affecting quality of life in individuals with critical congenital heart disease (CCHD) are neurodevelopmental challenges, including deficits in visuospatial processing and academic achievement. Few studies have compared outcomes across CCHD subgroups, despite their significant differences in anatomy/physiology and medical/surgical courses. This study compared visuospatial processing abilities using the Developmental Scoring System for the Rey-Osterrieth Complex Figure (DSS-ROCF) across groups of adolescents with CCHD (d-transposition of the great arteries [TGA, n = 139], Tetralogy of Fallot [TOF, n = 68], single-ventricle cardiac anatomy requiring the Fontan operation [SVF, n = 145]) and a group of healthy controls (CTR, n = 111), and examined the validity of visuospatial processing in predicting concurrent academic outcomes...

INTRODUCTION: Single-ventricle patients with elevated pulmonary vascular resistance (PVR) or end-diastolic pressure (EDP) are excluded from undergoing total cavopulmonary connection (TCPC). However, a subset of patients deemed to be at acceptable risk experience prolonged length of stay (LOS) after TCPC. Routine assessment of ventricular function has been inadequate in identifying these high-risk patients. Speckle-tracking echocardiography (STE) is a novel method for assessment of myocardial deformation that may be useful in single-ventricle patients...
