“…25 Previous studies evaluating RMN-guided AF ablation showed similar freedom of AF recurrence rates between manual and RMNguided RF ablation. 26,27 A recent prospective study observed an inferior performance of RMN compared to manual RF ablation, but investigated a different population including >60% of patients with persistent AF. 28 The current study observed for the first time an improved efficacy of RMN in the treatment of paroxysmal AF.…”

IntroductionPulmonary vein isolation (PVI) is a pivotal part of ablative therapy for atrial fibrillation (AF). Currently, there are multiple techniques available to realize PVI, including: manual‐guided cryoballoon (MAN‐CB), manual‐guided radiofrequency (MAN‐RF), and robotic magnetic navigation‐guided radiofrequency ablation (RMN‐RF). There is a lack of large prospective trials comparing contemporary RMN‐RF with the more conventional ablation techniques. This study prospectively compared three catheter ablation techniques as treatment of paroxysmal AF.MethodsThis multicenter, prospective study included patients with paroxysmal AF who underwent their first ablation procedure. Procedural parameters (including procedural efficiency), complication rates, and freedom of AF during 12‐month follow‐up, were compared between three study groups which were defined by the utilized ablation technique.ResultsA total of 221 patients were included in this study. Total procedure time was significantly shorter in MAN‐CB (78 ± 21 min) compared to MAN‐RF (115 ± 41 min; p < .001) and compared to RMN‐RF (129 ± 32 min; p < .001), whereas it was comparable between the two radiofrequency (RF) groups (p = .062). A 3% complication rate was observed, which was comparable between all groups. At 12‐month follow‐up, AF recurrence was observed in 40 patients (19%) and was significantly lower in the robotic group (MAN‐CB 19 [24%], MAN‐RF 16 [23%], RMN‐RF 5 [8%] AF recurrences, p = .045) (multivariate hazard ratio of RMN‐RF on AF recurrence 0.32, 95% confidence interval: 0.12–0.87, p = .026).ConclusionRMN‐guided PVI results in high freedom of AF in patients with paroxysmal AF, when compared to cryoablation and manual RF ablation. Cryoablation remains the most time‐efficient ablation technique, whereas RMN nowadays has comparable efficiency with manual RF ablation.

“…Numerous studies have shown RMN to be as effective as MC ablation (16)(17)(18), while reducing periprocedural complications and fluoroscopy exposure (19), but incidence of SCEs has not been reported. The purpose of this prospective pilot study was to examine the incidence of SCEs and investigate the potential risk predictors and possible mechanisms of SCEs in AF patients undergoing RMN-assisted PVI.…”

Background: The incidence of silent cerebral embolisms (SCEs) has been documented after pulmonary vein isolation using different ablation technologies; however, it is unreported in patients undergoing with atrial fibrillation (AF) ablation using Robotic Magnetic Navigation (RMN). The purpose of this prospective study was to investigate the incidence, risk predictors and probable mechanisms of SCEs in patients with AF ablation and the potential impact of RMN on SCE rates.Methods and Results: We performed a prospective study of 166 patients with paroxysmal or persistent AF who underwent pulmonary vein isolation. Patients were divided into RMN group (n = 104) and manual control (MC) group (n = 62), and analyzed for their demographic, medical, echocardiographic, and risk predictors of SCEs. All patients underwent cerebral magnetic resonance imaging within 48 h before and after the ablation procedure to assess cerebral embolism. The incidence and potential risk factors of SCEs were compared between the two groups. There were 26 total cases of SCEs in this study, including 6 cases in the RMN group and 20 cases in the MC group. The incidences of SCEs in the RMN group and the MC group were 5.77 and 32.26%, respectively (X2 = 20.63 P < 0.05). Univariate logistic regression analysis demonstrated that ablation technology, CHA2DS2-VASc score, history of cerebrovascular accident/transient ischemic attack, and low ejection fraction were significantly associated with SCEs, and multivariate logistic regression analysis showed that MC ablation was the only independent risk factor of SCEs after an AF ablation procedure.Conclusions: Ablation technology, CHA2DS2-VASc score, history of cerebrovascular accident/transient ischemic attack, and low ejection fraction are associated with SCEs. However, ablation technology is the only independent risk factor of SCEs and RMN can significantly reduce the incidence of SCEs resulting from AF ablation.Clinical Trial Registration: ChiCTR2100046505.
