简介
nMARQ AF Ablation
Background
nMARQ is a multipolar catheter designed to simultaneously ablate at multiple sites around the pulmonary vein (PV) circumference with a single radiofrequency application. We sought to define the safety and efficacy of atrial fibrillation (AF) ablation with the nMARQ catheter.
Methods
In a multicenter study, patients with drug‐refractory AF were included. Procedural outcomes were documented at 1 year.
Results
374 patients underwent PV isolation using nMARQ (age 60 ± 10 years, 264 male), of whom 263 patients had paroxysmal AF (PAF), while 111 patients had persistent AF. A total of 1,468 of 1,474 veins (99.6%) were isolated with the nMARQ catheter alone. Thirty‐five (13%) PAF patients and 30 (27%) persistent AF patients underwent additional ablation at non‐PV sites (2.4 ± 1.4 non‐PV sites). Procedure time for PV isolation only was 1.9 ± 0.7 hours (fluoroscopy 24 ± 14 …
