Article Synopsis
  • The study evaluates a new technique called Delta Wave Automatic Mapping for effectively identifying ablation sites in patients with Wolff-Parkinson-White Syndrome (WPW) undergoing radiofrequency catheter ablation (RFCA).
  • A total of 50 patients were analyzed, with all accessory pathways successfully ablated and a median time-to-effect of 2.0 seconds, showing no recurrences during a follow-up period of about 10 months.
  • The workflow eliminates the need for manual site localization by leveraging existing algorithms, relying on specific historical electrical parameters to enhance ablation success and precision.

Introduction: Patients with Brugada syndrome (BrS) face an increased risk of ventricular arrhythmias and sudden cardiac death. Implantable cardiac monitors (ICMs) have emerged as effective tools for detecting arrhythmias in BrS. Technological advancements, including temperature sensors and improved subcutaneous electrocardiogram (subECG) signal quality, hold promise for further enhancing their utility in this population.

Introduction: The dST-Tiso is a newly proposed electrocardiographic (ECG) marker during Brugada (BrS) type I pattern, that predicts the likelihood of ventricular arrhythmia (VA) inducibility in patients with ajmaline-induced pattern. The objective of this study was to validate the effectiveness of this criterion using an independent data set.

Methods: Consecutive patients exhibiting a BrS type I ECG pattern following ajmaline administration underwent programmed ventricular stimulation (PVS).

Article Synopsis
  • Recent data indicates that pulsed field ablation (PFA) technology for treating atrial fibrillation (AF) shows shorter procedural times as operators gain experience.
  • A study involving 752 patients found significant reductions in procedure time and fluoroscopy time as the number of PFA procedures increased among operators, with most procedures performed by those who had completed over 20 PFA cases.
  • The findings suggest that the PFA system is both efficient and safe for AF treatment, with a quick learning curve, enabling improved outcomes after just a small number of procedures.
