Antiarrhythmic therapy for narrow QRS supraventricular tachyarrhythmias in newborns and infants in the first year of life: Potent tools to be handled with care.

Supraventricular tachyarrhythmias pose a significant challenge in neonates and infants, particularly within the first year of life, where prompt and effective management is crucial. By synthesizing available evidence and clinical experience, this review aims to provide a comprehensive overview of antiarrhythmic therapy in this vulnerable population, with a focus on narrow QRS supraventricular tachyarrhythmias. This review examines the current understanding of supraventricular tachyarrhythmia management and discusses the challenges associated with antiarrhythmic therapy in newborns and infants during the critical first year of life, evaluating the efficacy and safety of various antiarrhythmic agents commonly utilized in this population, including dosing considerations, adverse effects, and strategies for acute management and prophylactic long-term antiarrhythmic treatment.

Exercise-induced type 1 Brugada pattern in a child.

The exercise stress testing may unmask the type 1 Brugada pattern on the surface electrocardiogram in a portion of patients with Brugada syndrome. The occurrence of the type 1 Brugada pattern during an exercise test in pediatric patients is not common. Consequently, the diagnostic yield of the exercise test in this population is still to be explored.

Effect of beta-blockers and angiotensin receptor blockers in reducing the aortic growth rate in children with bicuspid aortic valve-related aortopathy.

Aims: The aim of this study is to evaluate the effect of beta-blockers and angiotensin receptor blockers in reducing the aortic growth rate in children with bicuspid aortic valve (BAV)-related aortopathy and ascending phenotype.

Methods: Consecutive paediatric patients (≤16 years) with BAV and ascending aorta (AsAo) dilation (z-score > 3) were enrolled in this observational retrospective cohort study. Patients receiving prophylactic treatment with either atenolol (0.

Prevalence and Clinical Significance of Intraventricular Conduction Disturbances in Hospitalized Children.

Data on the prevalence and clinical significance of interventricular conduction disturbances (IVCDs) in children are scarce. While incomplete right bundle branch blocks (IRBBBs) seem to be the most frequent and benign findings, complete bundle blocks and fascicular blocks are often seen in children with congenital/acquired cardiac conditions. This study aims to delineate the prevalence and the diagnostic accuracy of IVCD in children admitted to a paediatric cardiology unit.

Irrigated contact force sensing catheter for redo ablation of slow-fast atrioventricular nodal reentrant tachycardia in pediatric and adolescent patients: A case series.

Conventional nonirrigated catheters cannot be able to create adequate lesions for effective slow pathway modulation in certain cases of pediatric atrioventricular nodal reentrant tachycardia ablation. Irrigated contact force sensing catheters may be considered in pediatric and adolescent patients to obtain a more extensive slow pathway modulation for redo ablation, avoiding dangerous radiofrequency applications close to the compact atrioventricular node or complex left-sided procedures.

[Clinical and genetic manifestations of left ventricular non-compaction in children].

Left ventricular non-compaction (LVNC) is a myocardial disease characterized by a two-layered structure typically seen at the apical and lateral left portions of the ventricular myocardium, distal to the papillary muscles. While considered a rare disease, its prevalence in children is increasing due to the increased awareness of this condition and improved resolution of imaging techniques. The etiology is heterogeneous, ranging from inherited conditions to acquired diseases.

Contact allergy to subcutaneous implantable cardioverter defibrillator in a child with Brugada syndrome.

Allergic reactions to components of cardiac implantable electronic devices are rare and often go undiagnosed, which can lead to a misdiagnosis of device infection. Contact allergy to subcutaneous implantable cardioverter defibrillator (S-ICD) is extremely rare. In this report, we present a case of cobalt-related contact allergy in a pediatric patient with Brugada syndrome who underwent S-ICD implantation.

RETRACTED: Left Ventricular Non-Compaction in Children: Aetiology and Diagnostic Criteria.

Left ventricular non-compaction (LVNC) is a heterogeneous myocardial disorder characterized by prominent trabeculae protruding into the left ventricular lumen and deep intertrabecular recesses. LVNC can manifest in isolation or alongside other heart muscle diseases. Its occurrence among children is rising due to advancements in imaging techniques.

Assessing the feasibility of using the antecubital vein to perform right heart catheterization in children and adults with congenital heart disease: a retrospective, observational single-center study.

Background: Right heart catheterization (RHC) usually is performed via the femoral vein or the internal jugular vein. However, the antecubital fossa vein is a valid venous access, and it has become increasingly popular to perform right heart catheterization utilizing this access.

Methods: A retrospective, observational study was conducted to describe use of the antecubital fossa vein for right heart catheterization in adults and children with congenital heart disease (CHD).

Contact force sensing radiofrequency catheter ablation guided by electroanatomic mapping in pediatric patients with permanent junctional reciprocating tachycardia: A case series.

Limited data are available on the use of irrigated contact force (CF) catheters for radiofrequency (RF) ablation of permanent junctional reciprocating tachycardia (PJRT) in children. We considered five consecutive pediatric patients with diagnosis of PJRT who underwent RF ablation with irrigated CF catheter guided by electroanatomic mapping, obtaining a low number of RF pulses and minimal fluoroscopy exposure. High CF values are not necessary to obtain effective RF lesions and successful ablation.

Organization and Activity of Italian Echocardiographic Laboratories: A Survey of the Italian Society of Echocardiography and Cardiovascular Imaging.

Background: The Italian Society of Echocardiography and Cardiovascular Imaging (SIECVI) conducted a national survey to understand better how different echocardiographic modalities are used and accessed in Italy.

Methods: We analyzed echocardiography laboratory activities over a month (November 2022). Data were retrieved via an electronic survey based on a structured questionnaire, uploaded on the SIECVI website.

Myocardial work in children with Wolff-Parkinson-White syndrome.

Wolff-Parkinson-White Syndrome (WPW) has been associated with reduced local myocardial deformation, and when left ventricular dysfunction is present, catheter ablation of the accessory pathway may be required, even in asymptomatic patients. We aimed to evaluate the diagnostic value of non-invasive myocardial work in predicting subtle abnormalities in myocardial performance in children with WPW.Seventy-five paediatric patients (age 8.

Clinical, Genetic, and Histological Characterization of Patients with Rare Neuromuscular and Mitochondrial Diseases Presenting with Different Cardiomyopathy Phenotypes.

Cardiomyopathies are mostly determined by genetic mutations affecting either cardiac muscle cell structure or function. Nevertheless, cardiomyopathies may also be part of complex clinical phenotypes in the spectrum of neuromuscular (NMD) or mitochondrial diseases (MD). The aim of this study is to describe the clinical, molecular, and histological characteristics of a consecutive cohort of patients with cardiomyopathy associated with NMDs or MDs referred to a tertiary cardiomyopathy clinic.
