Persistent Atrial Fibrillation (AF) APAC (Asia Pacific) Observational Study

NCT ID: NCT04244396

Last Updated: 2024-04-19

Basic Information

• Recruitment Status: TERMINATED
• Total Enrollment: 82 participants
• Study Classification: OBSERVATIONAL
• Study Start Date: 2020-02-25
• Study Completion Date: 2022-11-30

Brief Summary

The objective of this clinical trial is to collect safety and effectiveness data for the TactiCath™ Contact Force Ablation Catheter, Sensor Enabled™ (TactiCath SE) in the APAC patient population for the treatment of drug refractory, symptomatic persistent atrial fibrillation when following standard electrophysiology mapping and radiofrequency (RF) ablation procedures.

Detailed Description

The PerAF APAC trial is a prospective, single arm, non-randomized, observational, post-market clinical investigation. Approximately 100 subjects will be enrolled at up to 15 sites in South Korea, Singapore, Hong Kong, Taiwan, and India. Centers in other countries within APAC may be approached for participation in the clinical investigation as needed. Subjects will be followed for 15-months after their initial ablation procedure. The primary effectiveness and safety endpoints will be evaluated through 15-months. A core lab will independently assess AF/Atrial Flutter (AFL)/(Atrial tachycardia (AT) recurrence via Holter monitoring at the 6-month and 15-month follow-up visits. All serious adverse events (SAEs) will be independently adjudicated by qualified physicians not participating in the trial

Study Groups

Drug refractory, symptomatic persistent atrial fibrillation

Asian population

TactiCath™ Contact Force Ablation Catheter, Sensor Enabled™ (TactiCath SE)

Intervention Type: DEVICE

TactiCath SE is indicated for use in cardiac electrophysiological mapping (stimulation and recording), and, when used in conjunction with a radiofrequency generator, for cardiac ablation of supraventricular arrhythmias in the right and left atrium, including atrial fibrillation.

6. Any carotid stenting or endarterectomy

7. Documented or known left atrial thrombus on imaging

8. Left atrial (LA) diameter >50 mm (parasternal long axis view or by CT)

9. Left Ventricular Ejection Fraction (LVEF) <40%

10. Unable to take anticoagulation medication due to contraindication or intolerance

11. History of blood clotting or bleeding abnormalities

12. Myocardial Infarction (MI), acute coronary syndrome, Percutaneous coronary intervention (PCI) within the 3-months (90-days) prior to the initial procedure

13. Documented thromboembolic event (including TIA) within 12-months (365 days) prior to the initial procedure

14. Rheumatic heart disease

15. Uncontrolled heart failure or New York Heart Association (NYHA) Class III or IV

16. Severe mitral regurgitation (regurgitant volume ≥ 60 mL/beat, regurgitant fraction ≥ 50%, and/or effective regurgitant orifice area ≥ 0.40cm2)

17. Awaiting cardiac transplantation or other cardiac surgery within 12-months (365 days) following the initial ablation procedure

18. Unstable angina at the time of the initial procedure

19. Acute illness or active systemic infection or sepsis

20. AF secondary to electrolyte imbalance, thyroid disease, acute alcohol intoxication, major surgical procedure in the preceding 3-months, or other reversible or non-cardiac cause

21. Diagnosed atrial myxoma

22. Presence of implanted implantable cardioverter defibrillator (ICD) or cardiac resynchronization therapy-defibrillator (CRT-D)

23. Significant pulmonary disease, (e.g., restrictive pulmonary disease, constrictive or chronic obstructive pulmonary disease) or any other disease or malfunction of the lungs or respiratory system that produces chronic symptoms

24. Significant congenital anomaly or other anatomic or comorbid medical problem that in the opinion of the investigator would preclude enrollment in this study or compliance with the follow-up requirements or impact the scientific soundness of the clinical trial results

25. Pregnant or nursing subjects and those who plan pregnancy during the clinical investigation follow-up period

26. Enrollment in an investigational study evaluating another device, biologic, or drug that may interfere with this clinical investigation at the time of the initial procedure or within 30 days prior to the initial procedure

27. Presence of any condition that precludes appropriate vascular access or manipulation of catheter

28. Life expectancy less than 12-months

29. Body mass index >40 kg/m2

30. Known sensitivity to contrast media (if needed during the procedure) that cannot be controlled with pre-medication

31. Renal failure requiring dialysis

32. Presence of other medical, social, or psychological conditions that, in the investigator's opinion, could limit the subject's ability to participate in the clinical investigation or to comply with follow-up requirements, or impact the scientific soundness of the clinical investigation results

33. History of atriotomy or ventriotomy

34. Implanted left atrial appendage occlusion device
