Safety and feasibility of 3D-electroanatomical mapping-guided zero or near-zero fluoroscopy catheter ablation for pediatric arrhythmias: Meta-analysis.

Background: Catheter ablation in the pediatric population using fluoroscopy has been known to cause adverse events. This study aims to assess the effectiveness and safety of zero fluoroscopy (ZF) and near-ZF-guided catheter ablation for the treatment of arrhythmias in the pediatric population.

Methods: The PubMed, Embase, and Cochrane library databases were searched and reviewed for relevant studies.

Long-term outcomes of ventricular tachycardia ablation in repaired tetralogy of Fallot: Systematic review and meta-analysis.

Background: Ventricular tachycardia (VT) remains a risk in repaired Tetralogy of Fallot (rTOF); however, long-term benefits of VT ablation have not been established. This study compares the outcomes of rTOF patients with and without VT ablation.

Methods: We searched multiple databases examining the outcomes of rTOF patients who had undergone VT ablation compared to those without ablation.

Prevalence and risk factors analysis of early postoperative arrhythmia after congenital heart surgery in pediatric patients.

Background: Arrhythmia is one of the most common complications after cardiac surgery. The objectives of this study were to determine the prevalence and analyze the risk factors of postoperative arrhythmia in pediatric patients after cardiac surgery for congenital heart defects (CHD) at a single center in Bali, Indonesia over 2 years period.

Methods: A cross-sectional study, among 120 pediatric patients with CHD who underwent cardiac surgery, 92 patients met inclusion criteria in this study.

Future direction of substrate-based catheter ablation in Brugada syndrome and other inherited primary arrhythmia syndromes: Systematic review and meta-analysis.

Background: Inherited Primary Arrhythmias Syndromes (IPAS), especially Brugada syndrome (BrS), have been associated with arrhythmogenic substrates that can be targeted through ablation. This meta-analysis evaluated the outcomes of catheter ablation (CA) in different types of IPAS based on procedural guidance and location.

Methods: A systematic search was conducted across multiple databases to identify studies reporting on ventricular arrhythmia (VA) events before and after CA in IPAS, including BrS, Long-QT syndrome (LQTS), Early repolarization syndrome (ERS), and Idiopathic ventricular fibrillation (IVF).
