Atrial Fibrillation Ablation
Persistent AF independently predicts poor outcomes after catheter ablation
Persistent atrial fibrillation was associated with worse outcomes and less quality of life benefit after catheter ablation compared with paroxysmal AF, researchers reported.
Catheter ablation, but not medical therapy, improves anxiety and depression symptoms in AF
In patients with symptomatic atrial fibrillation, catheter ablation improved psychological symptoms of anxiety and depression compared with medical therapy, according to results of the REMEDIAL trial.
Catheter ablation safe, effective for AF in patients awaiting heart transplant
In patients with end-stage HF awaiting transplant, catheter ablation for atrial fibrillation was safe and effective and was associated with improvements in left ventricular ejection fraction and AF burden, a speaker reported.
Pulsed field ablation rivals thermal technique but with faster procedure times: ADVENT
In adults with paroxysmal atrial fibrillation, pulsed field ablation was noninferior to conventional thermal ablation for safety and efficacy, with significantly less pulmonary vein narrowing and faster procedure times, researchers stated.
FDA clears AI algorithms to gauge success of complex arrhythmia ablation
CathVision announced the FDA clearance and commercial availability of two algorithms as part of its artificial intelligence-powered EP recording system for ECG interpretation.
FDA approves cryoablation system for paroxysmal AF with expandable balloon catheter
Boston Scientific announced it received FDA approval for its cryoablation system indicated for the treatment of patients with paroxysmal atrial fibrillation.
FDA approves several radiofrequency AF ablation catheters for use without fluoroscopy
Biosense Webster announced several of its products in its cardiac ablation portfolio have received FDA approval for use without fluoroscopy.
For shock-resistant AF, traditional measures ‘fail to capture’ ablation’s true benefit
Implantable device data show patients with shock-resistant atrial fibrillation fare better than conventional analyses demonstrate, experiencing a marked reduction in atrial tachyarrhythmia burden despite modest arrhythmia-free survival.
Same-day discharge protocol identifies patients who respond well to AF ablation
Use of a standardized protocol identified candidates for same-day discharge after catheter ablation for atrial fibrillation and also predicted procedural outcomes, researchers reported at Heart Rhythm 2023.
Pulsed field ablation confers successful outcomes in real-world population
In the EU-PORIA real-world registry of patients with atrial fibrillation who underwent pulsed field ablation, most patients did not have recurrence at 1 year and the learning curve for operators was quick.
