Maternal poor glycemic control increases risk of neonatal left ventricular hypertrophy.

Background: Left ventricular hypertrophy (LVH) is an important complication of infants of diabetic mothers (IDMs). However, the defined factors, such as the influence of glycemic control, insulin administration of diabetic mothers and large for gestational age (LGA) in infants, are largely unknown on the incidence of LVH. Therefore, this study aimed to evaluate the prevalence of maternal and neonatal risk factors associated with LVH in IDMs.

Cardiac MRI evaluation of aortic biophysical properties in paediatric Turner syndrome.

Background: Aortopathy in Turner syndrome is associated with aortic dilation, and the risk of dissection is increased when the aortic size index is ≥ 2-2.5 cm/m. We evaluated the aortic biophysical properties in paediatric Turner syndrome using cardiac MRI to determine their relationship to aortic size index.

Impaired Single Right Ventricular Function Compared to Single Left Ventricles during the Early Stages of Palliation: A Longitudinal Study.

Background: Single right ventricles (SRV) are postulated to be disadvantaged compared with single left ventricles (SLV). We compared the evolution of SRV versus SLV function during infancy using conventional measures and speckle-tracking echocardiography (STE). We hypothesized that the SRV is mechanically disadvantaged during early infancy.

Cardiac Magnetic Resonance Imaging in Pediatric Turner Syndrome.

Objective: To compare the detection of cardiac lesions with the use of cardiac magnetic resonance imaging (CMR) and conventional echocardiography in children with Turner syndrome.

Study Design: Twenty-four girls with Turner syndrome, 8-18 years of age, were recruited through the Pediatric Endocrinology Program. Participants underwent CMR and echocardiography within a 2-year period, and discrepancies between the results of each modality were identified.

Childhood presentation of interrupted aortic arch with persistent carotid ducts.

Interrupted aortic arch is a rare condition with typical presentation within the first few weeks of life, as the circulation is dependent upon patency of the arterial duct. Most cases are associated with intracardiac anomalies, the most common being a ventricular septal defect with some degree of hypoplasia and/or obstruction of the left ventricular outflow tract. Presentation beyond infancy is uncommon, and suggests the presence of well-developed collateral circulation.
