The G protein-gated potassium current I(K,ACh) is constitutively active in patients with chronic atrial fibrillation

, 2005
Background— The molecular mechanism of increased background inward rectifier current (IK1) in atrial fibrillation (AF) is not fully understood. We tested whether constitutively active acetylcholine (ACh)-activated IK,ACh contributes to enhanced basal ...

Prospective Trial of Radiofrequency Catheter Ablation of High Dominant Frequencies After Pulmonary Vein Isolation in Non‐Paroxysmal Atrial Fibrillation (PAD‐AF Trial): A Multicenter, Randomized Clinical Trial

Journal of Cardiovascular Electrophysiology, EarlyView.
In persistent AF, adjunctive dominant frequency‐guided ablation after pulmonary vein isolation did not significantly improve outcomes. Limited overlap between high‐frequency sites and low‐voltage areas suggests functional–structural dissociation, while right atrial low‐voltage burden predicts recurrence.

Zero‐Contrast Versus Contrast‐Guided Left Atrial Appendage Occlusion: A Comparative Analysis of Procedural and Long‐Term Outcomes

Journal of Cardiovascular Electrophysiology, EarlyView.
Zero‐contrast left atrial appendage occlusion yielded high procedural success and similar periprocedural adverse event rates compared to the contrast‐guided approach. At 45‐day follow‐up, successful LAA closure (defined as peri‐device leak ≤ 5 mm) and device‐related thrombus rates were similar.

Intravenous pacemaker lead implantation for a pediatric patient: A 16-year follow-up study

Journal of Arrhythmia, 2013
Intravenous pacemaker lead implantation for small children is not performed routinely. Here, we report the case of a pediatric patient who underwent endocardial lead implantation and follow-up for 16 years.

Determinants of recurrent atrial flutter after cardioversion

, 1983
Eighteen male patients (mean age 59 years) who were electrically cardioverted for pure atrial flutter were retrospectively studied to determine those factors influencing the maintenance of regular sinus rhythm or reversion to atrial flutter.

Comparison of Two Pulsed Field Ablation Systems for Atrial Fibrillation: One‐Year Outcomes From a Multicenter Registry

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Background While various pulsed field ablation (PFA) systems for atrial fibrillation (AF) ablation have become available in recent years, data comparing long‐term efficacy outcomes remain limited. Purpose To compare long‐term efficacy outcomes of two commercially available PFA systems to perform pulmonary vein isolation (PVI) for AF in a ...
