“…With the innovation of CARTO technology, new functional software called pattern matching filter (PMF, Biosense Webster Inc) has been offered which enables a correlation to be made between the real time PVCs and the predefined template morphology. Limited studies have reported that PMF can improve the outcomes in manually controlled catheter ablation 8 . The object of this study was to evaluate the usefulness of PMF in combination with RMN for PVCs ablation.…”

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.
