Background Catheter-based pulmonary vein isolation is an effective treatment for
paroxysmal atrial fibrillation. Pulsed field ablation, which delivers microsecond high-voltage …

Abstract Background QDOT MICRO (QDM) is a novel contact force–sensing catheter
optimized for temperature-controlled radiofrequency (RF) ablation. The very high-power …

Objectives This study sought to determine whether durable pulmonary vein isolation (PVI)
using pulsed field ablation (PFA) translates to freedom from atrial fibrillation recurrence …

Background: Pulsed field ablation is a novel nonthermal cardiac ablation modality using
ultra-rapid electrical pulses to cause cell death by a mechanism of irreversible …

Background: Catheter ablation of atrial fibrillation using thermal energies such as
radiofrequency or cryothermy is associated with indiscriminate tissue destruction. During …

Abstract Objectives DIAMOND-AF (DiamondTemp™ Ablation System for the Treatment of
Paroxysmal Atrial Fibrillation) was a prospective, multicenter, noninferiority, randomized trial …

Background: Recurrent paroxysmal atrial fibrillation (AF) after catheter ablation is
presumably caused by failure to achieve durable pulmonary vein isolation (PVI). The …

BACKGROUND: The cryoballoon (CB) represents the gold standard single-shot device for
pulmonary vein isolation (PVI) in patients with atrial fibrillation (AF). Single-shot pulsed field …

Background Because of its safety,“single-shot” pulsed field ablation (PFA) catheters have
been developed for pulmonary vein isolation (PVI). However, most atrial fibrillation (AF) …

Background: Advanced generation ablation technologies have been developed to achieve
more effective pulmonary vein isolation (PVI) and minimize arrhythmia recurrence after atrial …
