“…The incidence of silent cerebral strokes seems to be substantially higher after thoracoscopic ablations. In our series of hybrid ablation patients, new acute ischemic lesions were seen on MRI in 44% of patients 2−4 days after the surgical procedure 12 . Moreover, compared to patients after CA, not only was the number of patients with new lesions greater after hybrid ablation but so was the number of lesions per patient 13 .…”

Background: Comparative data regarding the effect of percutaneous and thoracoscopic ablation of atrial fibrillation (AF) on cognitive function are very limited. The aim of the study was to determine and compare the effect of both types of ablations on patient cognitive functions in the mid-term.Methods: Patients with AF indicated for ablation procedure were included. Fortysix patients underwent thoracoscopic, off-pump ablation using the COBRA Fusion radiofrequency system, followed by a catheter ablation three months afterward (Hybrid group). A comparative cohort of 53 AF patients underwent pulmonary vein isolation only (PVI group). Neuropsychological examinations were done before and nine months after the surgical or catheter ablation procedure. Neuropsychological testing comprised 13 subtests of seven domains, and the results were expressed as post-operative cognitive dysfunction (POCD) nine months after the procedure.Results: Patients in both groups were similar with respect to the baseline clinical characteristics; only non-paroxysmal AF was more common in the hybrid group (98% vs. 34%). Major POCD was present in eight (17.4%) of hybrid patients versus three (5.7%) of PVI patients (p = 0.11), combined (major/minor) worsened cognitive decline was present in 10 (21.7%) hybrid patients versus three (5.6%) PVI patients (p = 0.034).On the other hand, combined (major/minor) improvement was present in 15 (32.6%) hybrid patients versus nine (16.9%) patients in the PVI group (p = 0.099). Conclusion:Hybrid ablation, a combination of thoracoscopic and percutaneous ablation, is associated with a higher risk of cognitive decline compared to sole percutaneous ablation.

“…Recently, given the close collaboration between cardiac surgeons and electrophysiologists, a one-stop sequential ablation strategy based on surgical/catheter ablation has been introduced with good results in patients with persistent AF. A related study demonstrated that this hybrid ablation model combines the advantages of intracardiac catheter ablation and epicardial surgical ablation, and to some extent can overcome the shortcomings of a single ablation technique ( 34 ). The rapid development of AF ablation technology has also led to innovations in ablation devices.…”

BackgroundCurrently, the bipolar radiofrequency ablation forceps manufactured by AtriCure are the main instrument for surgical ablation in patients with rheumatic heart disease (RHD) concomitant with atrial fibrillation (AF). The bipolar radiofrequency ablation forceps by Med-Zenith has a greater advantage in price compared with AtriCure. However, few studies have been reported on the comparison of their clinical efficacy. The aim of this study is to compare the short-term clinical efficacy of the two ablation forceps for RHD concomitant with AF.MethodsClinical data of 167 patients with RHD concomitant with AF admitted to the Department of Cardiac Major Vascular Surgery, Affiliated Hospital of North Sichuan Medical College, were retrospectively analyzed, and the restoration efficacy of sinus rhythm (SR) and cardiac function after surgery were compared with two ablation forceps.ResultsThe end-systolic diameter of the right atrium and the end-systolic diameter of the left atrium in the patients of both groups at each postoperative time point decreased compared with that of the preoperative period (P < 0.05), and the left ventricular ejection fraction started to improve significantly at 6 months after surgery compared with that of the preoperative period (P < 0.05). There was no difference between the two groups of patients in the comparison of the aforementioned indicators at different points in time (P > 0.05). At 12 months postoperatively, the SR maintenance rate in using the ablation forceps by Med-Zenith (73.3%) was lower than that for AtriCure (86.4%) and the cumulative recurrence rate of AF in using the Med-Zenith ablation forceps was greater than that for AtriCure.ConclusionsThe two bipolar radiofrequency ablation forceps compared in the study are safe and effective in treating patients of RHD concomitant with AF, and the ablation forceps by AtriCure may be more effective in restoring SR in the short term.

“…In a report by Osmancik et al, new silent ischemic lesions seen on early postoperative magnetic resonance imaging were present in 44.4% (ref. 86 ). In a meta-analysis of 22 single-center studies, including data from 925 patients (89% with non-paroxysmal AF), SR maintenance after hybrid ablation was present in 79.4% (95% CI, 72.4-85.7) and 70.7% (95%CI, 62.2-78.7) of patients with and without anti-arrhythmic drugs at 19 months of follow-up, respectively 87 .…”

Atrial fibrillation (AF), the most common cardiac arrhythmia is associated with increased morbidity and mortality. The higher mortality is due to the risk of heart failure and cardioembolic events. This in-depth review focuses on the strategies and efficacy of catheter ablation for non-paroxysmal atrial fibrillation. The main medical databases were searched for contemporary studies on catheter ablation for non-paroxysmal AF. Catheter ablation is currently proven to be the most effective treatment for AF and consists of pulmonary vein isolation as the cornerstone plus additional ablations. In terms of SR maintenance, it is less effective in non-paroxysmal AF than in paroxysmal patients. but the clinical benefit in non-paroxysmal patients is substantially higher. Since pulmonary vein isolation is ineffective, a variety of techniques have been developed, e.g. linear ablations, ablation of complex atrial fractionated electrograms, etc. Another paradox consists in the technique of catheter ablation. Despite promising results in early observation studies, further randomized studies have not confirmed the initial enthusiasm. Recently, a new approach, pulsed-field ablation, appears promising This is an in-depth summary of current technologies and techniques for the ablation of non-paroxysmal AF. We discuss the benefits, risks and implications in the treatment of patients with non-paroxysmal AF.
