Why the study?
Indications for thoracoscopic radiofrequency fragmentation of the left atrium in patients with paroxysmal atrial fibrillation were unclear.
Does thoracoscopic radiofrequency fragmentation of the left atrium with LAA resection reduce atrial fibrillation recurrence compared to cryoballoon ablation in patients with atrial fibrillation?
Cohort (n=194)
Does thoracoscopic radiofrequency fragmentation of the left atrium with LAA resection reduce atrial fibrillation recurrence compared to cryoballoon ablation in patients with atrial fibrillation?
Thoracoscopic radiofrequency fragmentation with LAA resection is associated with lower AF recurrence and reduced thromboembolic risk compared to cryoballoon ablation, suggesting it as a viable option for patients with paroxysmal AF and contraindications to anticoagulation.
Associated with lower AF recurrence in this cohort; leaves open whether thoracoscopic surgery should be preferred over cryoballoon ablation.

Vachev et al. (2021) conducted a cohort in Atrial fibrillation (n=194). Thoracoscopic radiofrequency fragmentation of the left atrium with resection of the left atrial appendage vs. Cryoballoon ablation of pulmonary veins was evaluated on Recurrence of atrial fibrillation (p=<0.001).
