Pulmonary-vein isolation is an effective treatment for paroxysmal atrial fibrillation. Pulsed field ablation (PFA) is a nonthermal ablation method with few adverse effects beyond the myocardium.

Participants were randomly assigned to receive pulmonary vein isolation with cryoablation or a sham procedure with phrenic nerve pacing (64 and 62 patients, respectively).

Doctors may use cryoablation to treat atrial fibrillation (AFib ... The tip of the catheter has a balloon that inflates at the opening of the pulmonary veins — the veins that return oxygenated ...

VIENNA, Austria—For patients with paroxysmal atrial fibrillation (AF), pulsed-field ablation with the Farapulse system (Boston Scientific) is as good as—and borderline better than—a cryoballoon for ...

Catheter ablation, also called radiofrequency or pulmonary vein ablation, isn't surgery. ... that makes circular scars around each vein or group of veins. Cryoablation.

Pulmonary vein isolation was associated with genuine improvements in patients with atrial fibrillation at 6 months that cannot be attributed to a placebo effect, researchers reported at the ...

New research shows that cryoablation is a safe and effective approach to close congenital patent foramen ovale (PFO, a small hole in the heart) in patients with atrial fibrillation (AF) undergoing ...

The POLARx cryoablation system has been cleared in Europe since early 2020 and in Japan as of October 2021. ... Once inserted in the pulmonary vein, ...

Catheter ablation, also called radiofrequency or pulmonary vein ablation, isn’t surgery, ... that creates circular scars around each vein or group of veins. Cryoablation: ...

The cumulative incidence of a recurrence of atrial tachyarrhythmia between day 91 and day 365 after ablation was 37.1% in the PFA group compared with 50.7% in the cryoablation group (between-group ...
