Abstract

Background: Previous studies reported the usefulness of an irrigated circular radiofrequency ablation catheter (nMARQ<sup>TM</sup>, Biosense Webster) for pulmonary vein isolation (PVI). We evaluated the role of intracardiac echocardiography (ICE) to optimize the manipulation of nMARQ<sup>TM</sup> catheter. Methods: Thirty-seven patients (pts), (mean age 55 ± 12 years; 28 males) were enrolled to perform PVI. All pts underwent PVI with the nMARQ<sup>TM</sup> catheter. In 20 pts (group 1), we utilized ICE to guide nMARQ<sup>TM</sup> catheter positioning at the PV ostia; in the other 17 pts (group 2), nMARQ<sup>TM</sup> catheter was positioned at the PV ostia guided by fluoroscopy and TissueConnect<sup>TM</sup> technology. Results: Radiofrequency (RF) applications were significantly lower in group 1 compared to group 2 [left PVs: 6 (range 3 to 12) in group 1 and 12 (range 5 to 16) in group 2 (p < 0.001); right PVs: 7 (range 4 to 14) in group 1 and 10 (range 5 to 16) in group 2 (p = 0.04)]; similarly regarding the time of RF delivery [left PVs: 318 ± 194 s in group 1 vs. 542 ± 104 s in group 2 (p < 0.001); right PVs: 410 ± 270 s in group 1 vs. 550 ± 156 s in group 2 (p = 0.05)]. Fluoroscopy time (23 ± 9 min vs. 28 ± 5 min; p = 0.05), procedural time (83 ± 23 min vs. 160 ± 42 min; p < 0.001), and radiation dose (109 ± 20 Gy/cm<sup>2</sup> vs. 127 ± 29 Gy/cm<sup>2</sup>; p = 0.04) were significantly lower in group 1 compared to group 2. Conclusion: ICE might be a useful tool to guide nMARQ<sup>TM</sup> catheter position in the left atrium during atrial fibrillation (AF) ablation procedures.
