NCT ID: NCT04652778

Last Updated: 2022-08-22

Basic Information

• Recruitment Status: UNKNOWN
• Clinical Phase: NA
• Total Enrollment: 15 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2021-09-15
• Study Completion Date: 2023-04-30

Brief Summary

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).

Eligibility Criteria

Inclusion Criteria

1. 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

2. 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

3. Age 18 through 75 years-old on the day of enrollment

4. Patient is indicated for an ablation procedure according to society guidelines or investigational site practice

5. Patient is willing and able to give informed consent.

6. Patient is willing, able, and committed to participate in baseline and follow-up evaluations for the full duration of the study.

Exclusion Criteria

1. Long-standing persistent AF (continuous AF sustained > 1 year)

2. AF secondary to electrolyte imbalance, thyroid disease, alcohol abuse, or other reversible/non-cardiac causes

3. Left atrial anteroposterior diameter > 5.0 cm as documented by transthoracic echocardiography (TTE) or computed tomography (CT) within 6 months prior to enrollment

4. Patient who is not on oral anticoagulation therapy for at least 3 weeks prior to the index ablation procedure

5. Use of amiodarone within 6 weeks prior to enrollment

6. Prior left atrial ablation or surgical procedure (including left atrial appendage (LAA) device or occlusion)

7. Planned LAA closure procedure or implant of a permanent pacemaker, biventricular pacemaker, loop recorder/insertable cardiac monitor (ICM), or any type of implantable cardiac defibrillator (with or without biventricular pacing function) for any time during the follow-up period

8. Presence of a permanent pacemaker, biventricular pacemaker, loop recorder/insertable cardiac monitor (ICM), or any type of implantable cardiac defibrillator (with or without biventricular pacing function)

9. Presence of any pulmonary vein stents

10. Presence of any pre-existing pulmonary vein stenosis

11. Pre-existing hemidiaphragmatic paralysis

12. Atrial or ventricular septal defect closure

13. Atrial myxoma

14. Presence of any prosthetic heart valve

15. Hemodynamically significant valvular disease

16. History of pericarditis

17. History of Rheumatic heart disease

18. History of thromboembolic event within 6 months of time of enrollment or evidence of intracardiac thrombus at time of procedure

19. Any of the following events within 3 months of enrollment

• Myocardial infarction (MI)
• Unstable angina
