Background This study's intent is to evaluate the usefulness of pattern matching filter (PMF) function combined with robotic magnetic navigation (RMN) in guiding the ablation of premature ventricular contractions (PVCs). Hypothesis Assume that PMF can improve the outcomes of PVCs ablation using RMN. Methods A retrospective analysis was completed consisting of 118 consecutive patients with PVCs who underwent radiofrequency ablation guided by RMN. According to the application of PMF, patients were divided into two groups: 20 patients underwent ablation without PMF (group A), and another 98 patients received ablation incorporating PMF (group B). Results Compared with group A, the procedure time (135.0 ± 28.3 min vs. 106.3 ± 37.9 min, p = 0.02) in group B was significantly decreased, while the X‐ray exposure time (6.0 ± 2.6 min vs. 6.5 ± 3.6 min, p = 0.705) and dose (3.2 ± 2.4 gycm2 vs. 3.9 ± 2.7 gycm2，p = 0.208) had no significant difference. Group B had a more than twofold number of points acquired (66.9 ± 23.0 vs. 143.9 ± 68.3, p < 0.001) and required a shorter radiofrequency ablation time (13.2 ± 3.5 min vs. 8.1 ± 2.9 min, p < 0.001). There were no serious complications in either group. The acute success rate was similar [90.0% (18/20) vs. 87.8% (86/98), p = 1.000] in two groups, and the success rate was also similar in the long‐term follow‐up [83.3% (15/18) vs. 87.2% (75/86), p = 0.776]. Conclusions The ablation of PVCs guided by RMN is safe and effective. Combined with the functional capability of PMF, both procedure time and radiofrequency ablation time were significantly decreased.

PreambleRobotic magnetic navigation (RMN)-guided catheter ablation (CA) technology has been used for the treatment of cardiac arrhythmias for almost 20 years. Various studies reported that RMN allows for high catheter stability, improved lesion formation and a superior safety profile. So far, no guidelines or recommendations on RMN-guided CA have been published.PurposeThe aim of this consensus paper was to summarize knowledge and provide recommendations on management of arrhythmias using RMN-guided CA as treatment of atrial fibrillation (AF) and ventricular arrhythmias (VA).MethodologyAn expert writing group, performed a detailed review of available literature, and drawing on their own experience, drafted and voted on recommendations and summarized current knowledge and practice in the field. Recommendations on RMN-guided CA are presented in a guideline format with three levels of recommendations to serve as a reference for best practices in RMN procedures. Each recommendation is accompanied by supportive text and references. The various sections cover the practical spectrum from system and patient set-up, EP laboratory staffing, combination of RMN with fluoroscopy and mapping systems, use of automation features and ablation settings and targets, for different cardiac arrhythmias.ConclusionThis manuscript, presenting the combined experience of expert robotic users and knowledge from the available literature, offers a unique resource for providers interested in the use of RMN in the treatment of cardiac arrhythmias.

Aim. To compare the long-term outcomes of the catheter ablation (CA) using remote magnetic-guided navigation (RMN) and manual radiofrequency CA (MAN) in patients with congenital heart defect (CHD) and incisional atrial tachyarrhythmias (AT).Methods. In this retrospective study cohort, 67 patients were included with CHD and AT. CHD were classified based on complexity (simple, moderate, and complex) according to ACC/AHA guidelines 2008. Fifty-seven (85%) patients underwent at least one surgical procedure for CHD correction before CA. The patients were divided into the two groups regarding CA approach: the MAN group (n=42) and the RMN group (n=25). The primary endpoitnts was long-term freedom from any AT, including atrial fibrillation. Key secondary endpoints included perioperative and late complications. To compare freedom from any AT between the groups, 1:3 propensity score matching was applied, and 63 patients were matched. The matching was exact on CHD complexity. The weighted matched observations were assessed with univariate Cox regression with any AT as the outcome.Results. The median follow-up period was 20 months. In the matched MAN and RMN groups, 92.3% and 83.3% patients, respectively, had incisional АТ (p=0.27), the other patients having additionally AF. The mean fluoroscopy time was statistically significant lower in the RMN group compared with MAN (р=0.009) with longer procedural duration in the RMN group (p<0.001). There was no statistically significant difference in perioperative and late complications. The freedom from any AT 36 months after CA was 78.9% in the matched RMN group and 47.2% in the matched MAN group. The comparison of freedom from any AT between the groups yielded p=0.040, hazard ration 0.32 [95% confidence interval 0.11; 0.95].Conclusion. RMN CA was superior over manual CA with respect to long-term freedom from AT in patients with CHD with similar safety profile.
