Article Synopsis
- The OmniaSecure defibrillation lead is a new, small-diameter lead aimed at improving targeted placement for better long-term performance in implantable cardioverter-defibrillators.
- The LEADR pivotal clinical trial involved 643 patients and showed that the lead was successfully placed in the correct position for 99.5% of participants, with a 97.5% success rate for defibrillation at implantation.
- The trial results indicated high safety and efficacy, with a 97.1% freedom from major complications and no lead fractures over an average follow-up of 12.7 months.
The COVID-19 pandemic accelerated adaption of a telehealth care model. We studied the impact of telehealth on the management of atrial fibrillation (AF) by electrophysiology providers in a large, multisite clinic. Clinical outcomes, quality metrics, and indicators of clinical activity for patients with AF during the 10-week period of March 22, 2020 to May 30, 2020 were compared with those from the 10-week period of March 24, 2019 to June 1, 2019.

The ECG Belt system (EBS) is a novel surface mapping system designed to measure electrical dyssynchrony via the standard deviation of the activation times of the left ventricle.
Objectives: The objectives of this study were to evaluate the efficacy of the EBS in patients less likely to respond to CRT and to determine whether EBS use in lead placement guidance and device programming was superior to standard CRT care.
Purpose: Compliance with anticoagulation treatment for atrial fibrillation is highly variable. Smartphone electrocardiograms that allow patients to have greater insight into their arrhythmia burden may improve anticoagulant compliance.
Methods: Patients were enrolled if they had atrial fibrillation with a CHADS-VASc score of 2 or more, were eligible for anticoagulation and had a smartphone.
Comparative outcomes of vascular access closure methods following atrial fibrillation/flutter catheter ablation: insights from VAscular Closure for Cardiac Ablation Registry.

August 2022
Purpose: This registry compared the safety and efficacy of vascular closure device Perclose (PC) with figure-of-eight stitch (Fo8) and manual compression (MC) following catheter ablation of atrial fibrillation/flutter.
Methods: VAscular Closure for Cardiac Ablation Registry (VACCAR) is a prospective, observational registry that assessed the time to hemostasis (TTH), time to ambulation (TTA), length of stay (LOS), complications, patient-reported outcomes, and pain medication use.
Results: A total of 434 patients (mean age 64.
