There is no current accepted and predictably effective ablative therapy for patients with recurrent paroxysmal atrial fibrillation after prior pulmonary vein isolation (PVI). This study will compare redo PVI with hybrid epicardial ablation incorporating posterior wall isolation and LAA clip, and redo PVI.
The purpose of this study it to learn whether pulmonary vein isolation (PVI) along with isolation of the posterior left atrial wall (PWI) in the region of the pulmonary venous component will reduce the likelihood of atrial fibrillation (AF) recurrence in patients with persistent atrial fibrillation at 12 months, after a single ablation procedure, in comparison to PVI alone. The investigator hypothesizes that the combination of PVI + PWI will result in a significant reduction in recurrence of atrial fibrillation at 12 months after ablation.
Atrial fibrillation is the most common arrhythmia. The posterior surface of the left atrium is covered by an extensive network belonging to the autonomic nervous system that can be damaged during the ablation. The involvement of the autonomous nervous system in the genesis and maintenance of atrial fibrillation remains poorly understood. Baroreflex sensitivity is a non-invasive method assessing autonomous nervous system activity. The rate of atrial fibrillation recurrence after ablation is currently high and a better understanding of the mechanisms associated with recurrence is essential to improve selection of the patients who will benefit the most from this procedure. The aim of this study is to evaluate the association between the baroreflex sensitivity and atrial fibrillation recurrences and to analyze the prognostic contribution of the baroreflex measurement compared to other published criteria.
Comparison among three different antithrombotic strategies after percutaneous LAA occlusion with a Watchman FLX LAAC device.
Thoracoscopic ablation is a promising treatment of persistent atrial fibrillation. However, the postoperative rehabilitation is very important to prevent early recurrence of atrial arrhythmia. The purpose of this study is to evaluate the efficacy of professional cardiac rehabilitation in patients after thoracoscopic ablation.
It is an attempt to see the reliability of the Wearable Smart Watch in identifying atrial fibrillation and other arrhythmias compared to the data detected from ILRs.
Catheter ablation has emerged as an important treatment option for patients with symptomatic atrial fibrillation (AF). Pulmonary vein antral isolation (PVI) is now considered the cornerstone technique of AF ablation and has shown promise in treating paroxysmal atrial fibrillation (PAF). However, there is no unique strategy for ablation of persistent AF (PeAF), whether PVI alone is sufficient to prevent patients from recurrence remains controversial. The PROMPT-AF study is a prospective, multicenter, randomized trial involving a blinded assessment of outcomes, which is designed to compare arrhythmia-free survival between PVI and an ablation strategy termed upgraded '2C3L' for ablation of PeAF.
The study aims to assess the right and left atrial electrophysiological substrate in atrial fibrillation patients using the invasive electroanatomic map (basal and with extraestimulus) as well as its correlation with cardiac magnetic resonance and electrocardiographic imaging. The results will also be compared when the patient is in sinus rhythm and atrial fibrillation.
