TactiFlex AF IDE Trial

This is an interventional treatment trial for Paroxysmal Atrial Fibrillation Read More

A patient will be eligible for clinical trial participation if he/she meets the following criteria:

1. Plans to undergo a catheter ablation procedure due to symptomatic PAF that is refractory or intolerant to at least one Class I or III antiarrhythmic drug.
2. Physician's note indicating recurrent self-terminating AF
3. One electrocardiographically documented AF episode within 12-months prior to informed consent/enrollment. Documented evidence of the AF episode must either be continuous AF on a 12-lead ECG or include at least 30 seconds of AF from another ECG device.
4. At least 18 years of age
5. Able and willing to comply with all trial requirements
6. Informed of the nature of the trial, agreed to its provisions and has provided written informed consent as approved by the Institutional Review Board/Ethics Committee (IRB/EC) of the respective clinical trial site.

A patient will be excluded from enrollment in the clinical trial if he/she meets any of the following criteria:

1. Persistent or long-standing persistent atrial fibrillation
2. Active systemic infection
3. Known presence of cardiac thrombus
4. Hypertrophic cardiomyopathy
5. Arrhythmia due to reversible causes including thyroid disorders, acute alcohol intoxication, and other major surgical procedures in the 90-day period preceding procedure
6. Myocardial infarction (MI), acute coronary syndrome, percutaneous coronary intervention (PCI), or valve or coronary bypass grafting surgery within 90 days of procedure
7. Left atrial diameter > 5.0 cm measured within 180 days of procedure (echocardiography or CT)
8. Left ventricular ejection fraction < 35% measured within 180 days of procedure (echocardiography or CT)
9. New York Heart Association (NYHA) class III or IV
10. Previous left atrial surgical or catheter ablation procedure
11. Left atrial surgical procedure or incision with resulting scar (including LAA closure device)
12. Previous tricuspid or mitral valve replacement or repair
13. Heart disease in which corrective surgery is anticipated within 180 days after the procedure
14. Bleeding diathesis or suspected pro-coagulant state
15. Contraindication to long term anti-thromboembolic therapy
16. Presence of any condition that precludes appropriate vascular access
17. Renal failure requiring dialysis
18. Known sensitivity to contrast media (if needed during the procedure) that cannot be controlled with pre-medication
19. Severe 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 severe chronic symptoms
20. Women who are pregnant or breastfeeding
21. Presence of other anatomic or comorbid condition that, in the investigator's opinion, could limit the patient's ability to participate in the clinical trial or to comply with follow up requirements, or impact the scientific soundness of the clinical trial results
22. Patient is currently participating in another clinical trial or has participated in a clinical trial within 30 days prior to screening that may interfere with this clinical trial
23. Patient is unlikely to survive the protocol follow up period of 12-months after the procedure
24. Body mass index > 40 kg/m2
25. 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.
26. Individuals without legal authority
27. Individuals unable to read or write
28. Patients who have had a ventriculotomy or atriotomy within the preceding 4 weeks of procedure,
29. Patients with prosthetic valves,
30. Patients with a myxoma,
31. Patients with an interatrial baffle or patch as the transseptal puncture could persist and produce an iatrogenic atrial shunt
32. Patient unable to receive heparin or an acceptable alternative to achieve adequate anticoagulation
33. Stroke or TIA (transient ischemic attack) within the last 90 days
34. Stent, constriction, or stenosis in a pulmonary vein.
35. Rheumatic heart disease
36. Severe mitral regurgitation (regurgitant volume ≥ 60 mL/beat, regurgitant fraction ≥ 50%, and/or effective regurgitant orifice area ≥ 0.40cm2).
