RESOLVE-AF: Clinical Evaluation of the Ablacath™ Mapping Catheter and Ablamap® System Utilizing Electrographic Flow (EGF) Mapping to Resolve Extra-PV Sources of Atrial Fibrillation and Guide Ablation Therapy.
Study Phase: N/A
Recruitment Status: Recruiting
Start Date: October 23, 2023
End Date: March 31, 2025
Inclusion Criteria:
1. Suitable candidate for intra-cardiac mapping and ablation of atrial arrhythmias including atrial fibrillation, atrial flutter and/or atrial tachycardia
2. Above eighteen (18) years of age or of legal age to give informed consent specific to state and national law
3. Left atrial (LA) diameter ≤ 5.5 cm or LA volume index ≤ 50 mL/m2 (use whichever measure is available or if both available, use the lesser of the two to qualify)
Exclusion Criteria:
1. De Novo paroxysmal AF
2. AF from a reversible cause (e.g., surgery, hyperthyroidism, sarcoidosis, or pericarditis, etc.)
3. Cardiac surgery or intervention within the past 90 days (e.g. percutaneous coronary intervention, ablation for ventricular arrhythmias, left atrial appendage occlusion devices, atrial septal defect closure devices, transcatheter aortic valve replacement)
4. Presence of transvenous pacing or defibrillator leads or an atrial leadless pacemaker
5. Myocardial infarction within the past 90 days
6. Severe valvular disease or prosthetic valve(s)
7. Contraindication to therapeutic anticoagulation
8. Decompensated heart failure or New York Heart Association (NYHA) Functional Class IV
9. Positive pregnancy test
10. Any other contraindication to an intracardiac mapping and ablation of atrial arrhythmias
11. Enrollment in another investigational study evaluating another device, biologic or drug
