Findings from repeat ablation using high-density mapping after pulmonary vein isolation with pulsed field ablation

Shota Tohoku et al.

Summary: Pulsed-field ablation can effectively reduce the risk of pulmonary vein reconnection during atrial fibrillation ablation. However, macro-reentrant atrial tachycardia with a critical isthmus linked to the pulmonary vein isolation lesion set is frequently observed.

Magnetic resonance assessment of left atrial scar formation following a novel very high-power short-duration workflow for atrial fibrillation ablation

Vanessa Sciacca et al.

Summary: This study evaluated the procedural data and the scar formation in atrial fibrillation (AF) patients who underwent ablation using high-power and short-duration (vHPSD) energy delivery. The results showed that vHPSD ablation resulted in shorter procedure duration, high efficacy, and durable pulmonary vein (PV) lesions. Cardiac magnetic resonance imaging (MRI) demonstrated homogeneous and contiguous scar formation. The advantages of vHPSD ablation are the quick and effective procedure, while the limitation is the small sample size.

Pulsed-field ablation-based pulmonary vein isolation: acute safety, efficacy and short-term follow-up in a multi-center real world scenario

Marc D. Lemoine et al.

Summary: The purpose of this study was to evaluate the efficacy, safety, and follow-up of pulsed-field ablation (PFA)-based pulmonary vein isolation (PVI) in an early adopter routine care setting. The results showed that PFA-based PVI is highly effective and associated with a beneficial safety and low recurrence rate. The follow-up results also confirmed its long-term treatment effects on arrhythmia.

Does pulsed field ablation regress over time? A quantitative temporal analysis of pulmonary vein isolation

Iwanari Kawamura et al.

Summary: This study found that the level of PV antral isolation observed after PFA did not regress over time, indicating the persistent effectiveness of PFA.

How does the level of pulmonary venous isolation compare between pulsed field ablation and thermal energy ablation (radiofrequency, cryo, or laser)?

Iwanari Kawamura et al.

Summary: This study compared the efficacy of pulsed field ablation and thermal ablation technologies in terms of pulmonary vein isolation, and found that there was no significant difference between the two methods in terms of left and right pulmonary vein isolation areas and the non-ablated posterior wall area.

Safety, effectiveness, and quality of life following pulmonary vein isolation with a multi-electrode radiofrequency balloon catheter in paroxysmal atrial fibrillation: 1-year outcomes from SHINE

Richard Schilling et al.

Summary: The study evaluated the safety and effectiveness of a compliant multi-electrode radiofrequency balloon catheter for pulmonary vein isolation in patients with atrial fibrillation. The results showed favorable outcomes, with low rates of adverse events and repeat ablation, as well as significant improvements in patients' quality of life.
