Pulmonary Vein Isolation

CHICAGO — For patients with atrial fibrillation and obesity, lifestyle modification plus antiarrhythmic drug therapy conferred various benefits but was inferior to catheter ablation for preventing recurrent AF, researchers reported.

Atrial fibrillation is a complex disease with ever-increasing treatment options, such as ablation, and advanced electrophysiology fellowship training is key to improving long-term outcomes, according to a new consensus statement.

The American Heart Association Scientific Sessions will be held in-person only in Chicago from Nov. 16 to 18 and will feature eight late-breaking science sessions during the 3-day meeting.

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 European Society of Cardiology Congress.

Tailored ablation guided by AI was linked to better 1-year outcomes than pulmonary vein isolation alone for patients with persistent atrial fibrillation, according to the results of the TAILORED-AF trial presented at Heart Rhythm 2024.

In a real-world registry of patients with atrial fibrillation treated with a pulsed field ablation catheter, the system was associated with favorable 30-day outcomes, researchers reported at Heart Rhythm 2024.

The FDA approved a second pulsed field ablation system for the treatment of adults with drug-refractory, recurrent, symptomatic, paroxysmal atrial fibrillation.

Medtronic announced the FDA approved its pulsed field ablation system for treatment of both paroxysmal and persistent atrial fibrillation via pulmonary vein isolation.

Ostial and antral pulmonary vein isolation, ablation plus posterior wall isolation and cryoablation all demonstrated comparable success in treating persistent atrial fibrillation, according to a post hoc analysis of the DECAAF II trial.

CathVision announced the FDA clearance and commercial availability of two algorithms as part of its artificial intelligence-powered EP recording system for ECG interpretation.
