Background: High-power short-duration radiofrequency ablation has improved lesion durability in pulmonary vein isolation. In this study, we investigate long-term clinical out-comes of high-power short-duration pulmonary vein isolation and posterior wall debulking as an initial treatment modality in all corner atrial fibrillation patients.

Methods: This is a single-center, retrospective, observational study including all patients who have undergone high-power short-duration pulmonary vein and posterior wall debulking, regardless of atrial fibrillation type and/or duration. High-power short-duration power delivery protocol was defined as 45 W at all ablation sites. Clinical and electrocardiographic follow-up were performed in all patients.

Results: One hundred forty-two patients were enrolled in this study. Paroxysmal atrial fibrillation was present in 88 (62%) of patients. The mean follow-up of this study was
36.9 months ± 12.2 months. During the follow-up period, 10 patients (11.4%) with a diagnosis of paroxysmal atrial fibrillation had recurrence, while recurrence in patients with persistent and long-standing persistent atrial fibrillation was slightly higher (15 patients (28.1%) and 5 patients (50%), respectively). No major life-threatening complications occurred.

Conclusion: This study has demonstrated excellent arrhythmia-free outcomes in unselected, real world atrial fibrillation patients undergoing high-power short-duration pulmonary vein and debulking posterior wall isolations, however larger randomized trials are warranted.
