Radiofrequency ablation of premature ventricular contractions guided by robotic magnetic navigation combined with pattern matching filter.

ABSTRACT:

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 signi
