About
This is a prospective, single-arm, open-label clinical study following patients to 1 year, to evaluate the safety and performance of the Centauri system for catheter ablation of atrial fibrillation (AF). The study will include adult patients (age 18-75 years) who are indicated for a first-time catheter ablation of AF where the pre-procedure treatment plan contemplates pulmonary vein isolation (PVI) in patients with paroxysmal AF (PAF), and PVI - with or without additional left atrial ablations - in patients with Persistent AF (PeAF) of short duration (< 1 year).

Inclusion criteria
Failure of at least one antiarrhythmic drug (AAD) (Class I - IV) for AF, as evidenced by recurrent symptomatic AF or intolerable side effects due to AAD
Diagnosis of recurrent symptomatic paroxysmal AF (PAF) or short duration (< 1 year) Persistent AF (PeAF) with the following documentation:
a. PAF i. Physician's note indicating symptoms consistent with recurrent symptomatic PAF AND ii. ≥ 2 episodes of PAF within 12 months prior to enrollment. At least one episode should be documented by ECG, transtelephonic monitor (TTM), Holter monitor, telemetry strip or similar, showing at least 30 seconds of AF b. PeAF i. Physician's note indicating symptoms consistent with continuous AF episode lasting longer than 7 days but less than 1 year AND ii. Any 24-hour continuous ECG recording documenting persistent AF within 6 months prior to enrollment OR iii. Two ECGs from any form of rhythm monitoring showing continuous AF taken at least 7 days apart within 12 months prior to enrollment OR iv. History of direct current cardioversion (DCCV) performed within 12 months prior to enrollment
Age 18 through 75 years-old on the day of enrollment
Patient is indicated for an ablation procedure according to society guidelines or investigational site practice
Patient is willing and able to give informed consent.
Patient is willing, able, and committed to participate in baseline and follow-up evaluations for the full duration of the study.
Exclusion criteria
