Long-Term Antibody Response to SARS-CoV-2 in Children.

Almost 2 years into the pandemic and with vaccination of children significantly lagging behind adults, long-term pediatric humoral immune responses to SARS-CoV-2 are understudied. The C19.CHILD Hamburg (COVID-19 Child Health Investigation of Latent Disease) Study is a prospective cohort study designed to identify and follow up children and their household contacts infected in the early 2020 first wave of SARS-CoV-2.

Narrative review of Ebstein's anomaly beyond childhood: Imaging, surgery, and future perspectives.

Ebstein's anomaly is a rare congenital heart disease with malformation of the tricuspid valve and myopathy of the right ventricle. The septal and inferior leaflets adhere to the endocardium due to failure of delamination. This leads to apical displacement of their hinge points with a shift of the functional tricuspid valve annulus towards the right ventricular outflow tract with a possibly restrictive orifice.

Retrieval of a Dislocated Stent Using a Grasping Forceps and a Steerable Sheath in a Fontan Patient.

In Fontan patients, any pulmonary stenosis may impede free passive inflow into the pulmonary circuit and elevate central venous pressure. When stenting such pulmonary stenosis, dislocation of a stent is a feared complication. Here, we report on a successful retrieval of a dislocated Cook Formula stent into the peripheral left pulmonary artery in a Fontan patient with protein-losing enteropathy using a steerable sheath and a grasping forceps.

Using three-dimensional visualization as an optimal tool to plan and validate an aortopexy in a congenital heart disease patient with severe tracheal stenosis.

We present a patient with severe tracheal stenosis resulting from a compression by the innominate artery 6 months after an arterial switch operation in a dextro-transposition of the great arteries. Segmentation and three-dimensional (3D) visualization were derived from a contrast-enhanced dual-source computed tomography and post-processing was performed using a dedicated open-source platform (3D Slicer). Post-processing allowed a comprehensible visualization of the relationship of the innominate artery to the trachea when compared to standard computer tomography reformations.

Right aortic arch forming a true vascular ring: a clinical review.

Objectives: This review aims at presenting and summarizing the current state of literature on the presentation and surgical management of a right-sided aortic arch with a left-sided ligamentum forming a complete vascular ring around the oesophagus and trachea.

Methods: A systematic database search for appropriate literature was conducted on PubMed/MEDLINE. Articles were considered relevant when providing details on the presentation, diagnosis and surgical treatment of this specific congenital arch anomaly in human beings.

Impact of hepatopathy in pediatric patients after surgery for complex congenital heart disease.

Patients undergoing complex pediatric cardiac surgery in early infancy are at risk of postoperative secondary end-organ dysfunction. The aim of this study was to determine specific risk factors promoting the development of peri- and postoperative hepatopathy after surgery for congenital heart disease. In this retrospective study, we identified 20 consecutive patients operated between 2011 and 2019 from our institutional cohort who developed significant postsurgical hepatic dysfunction.

Sensitivity of High-Pitch Dual-Source Computed Tomography for the Detection of Anomalous Pulmonary Venous Connection in Infants.

Purpose:  To evaluate the sensitivity, specificity, and interobserver reliability of high-pitch dual-source computed tomography angiography (CTA) in the detection of anomalous pulmonary venous connection (APVC) in infants with congenital heart defects and to assess the associated radiation exposure.

Materials And Methods:  78 pulmonary veins in 17 consecutively enrolled patients with congenital heart defects (6 females; 11 males; median age: 6 days; range: 1-299 days) were retrospectively included in this study. All patients underwent high-pitch dual-source CTA of the chest at low tube voltages (70 kV).
