polymorphisms are associated with susceptibility to Kawasaki disease but do not predict intravenous immunoglobulin resistance and coronary artery aneurysms.

Introduction: Kawasaki disease (KD) is a pediatric vasculitis that can result in coronary artery aneurysm (CAA) formation, which is a dangerous complication. Treatment with intravenous immunoglobulin (IVIg) significantly decreases the risk of CAA, possibly through competitive binding to Fc-gamma receptors (FcRs), which reduces the binding of pathological immune complexes. However, ~20% of children have recrudescence of fever and have an increased risk of CAA.

Sport activities for children and adolescents: the Position of the European Academy of Paediatrics and the European Confederation of Primary Care Paediatricians 2023-Part 1. Pre-participation physical evaluation in young athletes.

The European Academy of Paediatrics (EAP) and the European Confederation of Primary Care Paediatricians (ECPCP) emphasize the importance of promoting healthy lifestyles within the pediatric population. Many health professionals have questions concerning adequate levels of physical activity for both the healthy pediatric population and for those who may have specific complications. Unfortunately, the academic literature that provides recommendations for participation in sport activities within the pediatric population that have been published during the last decade in Europe is limited and is mainly dedicated to specific illnesses or advanced athletes and not toward the general population.

Imaging Features of Pediatric Left Ventricular Noncompaction Cardiomyopathy in Echocardiography and Cardiovascular Magnetic Resonance.

Left ventricular noncompaction (LVNC) is a distinct cardiomyopathy characterized by the presence of a two-layer myocardium with prominent trabeculation and deep intertrabecular recesses. The diagnosis of LVNC can be challenging because the diagnostic criteria are not uniform. The aim of our study was to evaluate echocardiographic and CMR findings in a group of children with isolated LVNC.

Right-ventricular mechanics assessed by cardiovascular magnetic resonance feature tracking in children with hypertrophic cardiomyopathy.

Background: Although hypertrophic cardiomyopathy (HCM) is considered a disease of the left ventricle (LV), right ventricular (RV) abnormalities have also been reported on. Cardiovascular magnetic resonance feature tracking (CMR-FT) accurately and reproducibly quantifies RV myocardial deformation.

Aim: To investigate RV deformation disorders in childhood HCM using CMR-FT.

Association Between rs12037447, rs146732504, rs151078858, rs55723436, and rs6094136 Polymorphisms and Kawasaki Disease in the Population of Polish Children.

Kawasaki disease (KD) is an acute self-limited febrile vasculitis that mainly affects young children. Coronary artery involvement is the most serious complication in children with KD. It is currently the leading cause of acquired cardiac disease in children from developed countries.

The Indices of Cardiovascular Magnetic Resonance Derived Atrial Dynamics May Improve the Contemporary Risk Stratification Algorithms in Children with Hypertrophic Cardiomyopathy.

Introduction: The most efficient risk stratification algorithms are expected to deliver robust and indefectible identification of high-risk children with hypertrophic cardiomyopathy (HCM). Here we compare algorithms for risk stratification in primary prevention in HCM children and investigate whether novel indices of biatrial performance improve these algorithms.

Methods And Results: The endpoints were defined as sudden cardiac death, resuscitated cardiac arrest, or appropriate implantable cardioverter-defibrillator discharge.

Edwards Inspiris Resilia® valve for mitral replacement in an infant after mechanical valve failure.

We present the surgical implantation of the Edwards Inspiris Resilia® aortic valve in mitral position for mechanical mitral valve failure in a severely ill infant after valve replacement because of anomalous origin of the left coronary artery from the pulmonary artery. The biological valve was chosen because the child could not receive oral anticoagulation and was for several months on heparin infusion. The procedure was safely performed with good haemodynamic result.
