Introduction: Pulsed-field ablation (PFA) is a novel modality for pulmonary vein isolation in patients with atrial fibrillation (AF). We describe the initial uptake and experience of PFA using a pentaspline catheter across selected National Health Service England (NHSE) centres.

Methods: Data collected by NHSE Specialised Services Development Programme regarding AF ablation procedures using a single-shot, pentaspline, multielectrode PFA catheter (FARAWAVE, Boston Scientific) between June 2022 and August 2024 were aggregated and analysed to examine procedural metrics, acute efficacy and safety outcomes over 3-month follow-up.

Article Synopsis
  • - The experiment at Lawrence Berkeley National Laboratory aimed to produce a superheavy element with an atomic number of 114 or greater by bombarding an actinide target with a ^{50}Ti beam.
  • - Using the Berkeley Gas-filled Separator, researchers successfully isolated and implanted produced Livermorium (Lv) ions into a high-tech detector system, observing two decay chains linked to ^{290}Lv.
  • - The measured production cross-section of the process was 0.44 picobarns at a specific energy, marking the first published evidence of superheavy element production near the "island of stability" with this method, paving the way for future discoveries beyond element Z=118.

Article Synopsis
  • The study aimed to compare the effectiveness of manual compression (MC) and two suture-based techniques (Fo8 and modified Fo8) for femoral venous haemostasis after electrophysiology procedures, hypothesizing that Fo8 would lead to better short-term bleeding outcomes than MC.
  • In a sample of 1,089 patients, Fo8 showed significantly fewer major and minor complications compared to MC, particularly in those receiving anticoagulation during the procedure.
  • The findings suggest that the Fo8 technique significantly reduces the risk of access site complications after these procedures, indicating it may be a preferred method for achieving haemostasis.

Article Synopsis
  • Direct current cardioversion (DCCV) is a procedure used to treat atrial fibrillation, and a study compared follow-up methods between remote photoplethysmography (PPG) and traditional 12-lead electrocardiograms (ECG).
  • The analysis involved 416 patients, showing high compliance rates for both methods, but PPG was more cost-effective, saving money and travel time for patients while also reducing carbon emissions.
  • Ultimately, the study concluded that remote PPG monitoring is a practical alternative for post-DCCV arrhythmia follow-up, with no safety concerns reported.

Background: Patients who have recurrent atrial fibrillation (AF) following redo catheter ablation may eventually be managed with a pace-and-ablate approach, involving pacemaker implant followed by (AVNA). We sought to determine which factors would predict subsequent AVNA in patients undergoing redo AF ablation.

Methods: We analyzed patients undergoing redo AF ablations between 2013 and 2019 at our institution.
