Use of ivabradine in children with junctional ectopic tachycardia after pediatric cardiac surgery; two-centre experience.

Introduction: Although amiodarone is traditionally used in the treatment of postoperative junctional ectopic tachycardia (JET), the search for new treatments is ongoing. We present our experience with ivabradine at two medical centers.

Materials And Methods: Between January 2022 and January 2023, patients who developed JET after pediatric cardiac surgery were prospectively followed up and documented.

Sinus node dysfunction in children: different aetiologies, similar clinical course in two-centre experience.

Aim: This study aims to evaluate the clinical characteristics and outcomes of children diagnosed with sinus node dysfunction.

Methods: This was a retrospective review of patients diagnosed with sinus node dysfunction in two tertiary paediatric cardiology centres in Turkey from January 2011 to June 2022.

Results: In all, 77 patients (50, 64.

Evaluation of T-wave memory after accessory pathway ablation in pediatric patients with Wolff-Parkinson-White syndrome.

Background: T-wave memory (TWM) is a rare cause of T-wave inversion (TWI). Alterations in ventricular activation due to abnormal depolarization may cause repolarization abnormalities on the ECG, even if myocardial conduction returns to normal. These repolarization changes are defined as TWM.

Non-binary gender, vulnerable populations and mental health during the COVID-19 pandemic: Data from the COVID-19 MEntal health inTernational for the general population (COMET-G) study.

Background: The COVID-19 pandemic has brought significant mental health challenges, particularly for vulnerable populations, including non-binary gender individuals. The COMET international study aimed to investigate specific risk factors for clinical depression or distress during the pandemic, also in these special populations.

Methods: Chi-square tests were used for initial screening to select only those variables which would show an initial significance.

Permanent pacemaker implantation with hybrid endocardial perventricular approach in infancy: May be an alternative route in the absence of epicardial lead.

Despite the advancements in technology, establishing the optimal implantation technique for pediatric patients with a pacemaker (PM) indication remains challenging. Although the implantation of an epicardial PM is recommended, especially in children weighing less than 10 kg, transventricular placement of endocardial leads can be performed safely, offering a practical substitute for an epicardial pacing system, particularly in situations where a transvenous approach is unfeasible due to patient size, anatomical constraints or epicardial PM leads were not available as in our case.
