Pulmonary Vein Isolation
Electrographic flow-guided ablation appears to benefit redo patients with nonparoxysmal AF
Electrographic flow-guided ablation was associated with improvement in freedom from atrial fibrillation at 1 year compared with standard pulmonary vein isolation in patients with nonparoxysmal AF requiring a redo ablation, data showed.
High-power short-duration AF ablation modestly reduces procedure time
A novel catheter for very high-power short-duration ablation for pulmonary vein isolation in patients with atrial fibrillation modestly reduced procedure time compared with standard ablation, according to data from the POWER PLUS trial.
Posterior wall isolation does not improve outcomes in ablation for persistent AF
In patients with persistent atrial fibrillation undergoing catheter ablation, adding posterior wall isolation to pulmonary vein isolation did not improve rates of AF recurrence compared with pulmonary vein isolation alone, data show.
Novel very high-power short-duration ablation for pulmonary vein isolation ‘safe, effective’
A novel catheter for very high-power short-duration ablation for pulmonary vein isolation reduced procedure time with similar atrial fibrillation/atrial tachycardia recurrence at 1 year vs. standard ablation, researchers reported.
AI-based index-tagging module improves ablation performance in paroxysmal AF
An artificial intelligence-based module to help achieve more effective pulmonary vein isolation in patients undergoing catheter ablation for paroxysmal atrial fibrillation was associated with high rates of success, researchers reported.
LAA ligation device safe, successful in persistent AF
The Lariat left atrial appendage ligation device was safe and successful at excluding the left atrial appendage in patients with persistent atrial fibrillation, researchers reported at the American Heart Association Scientific Sessions.
Fibrosis ablation not superior to PVI, but promising in early stages of atrial myopathy
In patients with persistent atrial fibrillation, a strategy of ablation based on MRI assessment of atrial fibrosis was not superior to pulmonary vein isolation for prevention of arrhythmia recurrence, researchers reported.
RACE-AF
Radiofrequency vs. cryoballoon ablation for reducing atrial fibrillation burden in patients with paroxysmal AF.
Catheter ablation methods for AF result in similar pulmonary vein isolation durability
Pulmonary vein isolation durability was similar after treatment with radiofrequency or cryoballoon catheter ablation in patients with paroxysmal atrial fibrillation, according to results of the RACE-AF trial.
Cryoballoon ablation for persistent AF safe with low event rate
Pulmonary vein isolation with cryoballoon ablation was safe and effective in patients with persistent atrial fibrillation during 12-month follow-up, according to data from the STOP Persistent AF trial.
