Background: Patients with transposition of the great arteries (TGA) who undergo atrial switch procedures may develop symptomatic atrial arrhythmias necessitating ablation. We present a single-centre retrospective analysis of a novel approach using jugular access for catheter ablation in this unique patient population.
Methods: A 5-year retrospective analysis was conducted on patients referred for atrial arrhythmia ablation following atrial switch procedures.
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.
