Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The NEwTON AF study is a multi-center, global, prospective, single arm study to establish the safety and effectiveness of the IntellaNav StablePoint Catheter and Force-Sensing System in subjects with symptomatic, drug refractory, recurrent paroxysmal atrial fibrillation.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. History of recurrent symptomatic Paroxysmal Atrial Fibrillation (PAF), defined as atrial fibrillation (AF) that terminates spontaneously or with intervention (either procedure or drug therapy) within seven days of onset. Minimum documentation includes the following:

a physician's note indicating recurrent self-terminating atrial fibrillation (AF) which includes at least two symptomatic AF episodes in the patient's history within the last 6 months prior to enrollment, and any electrocardiographically documented AF episode within 12 months prior to enrollment.
2. Subjects who are eligible for an ablation procedure for PAF according to 2017 HRS expert consensus statement on catheter ablation of atrial fibrillation;
3. Subjects refractory or intolerant to at least one class I or class III antiarrhythmic medication or contraindicated to any class I or class III medications;
4. Subjects who are willing and capable of providing informed consent;
5. Subjects who are willing and capable of participating in all testing associated with this clinical investigation at an approved clinical investigational center;
6. Subjects whose age is 18 years or above, or who are of legal age to give informed consent specific to state and national law.

Exclusion Criteria

1. Subjects with New York Heart Association (NYHA) Class III or IV heart failure \< 180 days prior to enrollment
2. Left atrial diameter \> 5.0 cm or left atrial volume \>50 ml/m² indexed based on the most recent echocardiography+
3. Left ventricular ejection fraction \< 35% based on the most recent echocardiogram +
4. Continuous AF lasting longer than seven (7) days
5. Subjects who have undergone any previous left atrial cardiac ablation (RF, Cryo, surgical)
6. Atrial fibrillation secondary to electrolyte imbalance, thyroid disease, or reversible or non-cardiac cause
7. Subjects who have undergone any cardiac ablation or any surgery within 30 days prior to enrollment
8. Currently implanted with a pacemaker, ICD, CRT device, or an implanted arrhythmia loop recorder
9. Active systemic infection
10. Unstable angina or ongoing myocardial ischemia
11. Myocardial Infarction (MI) within 90 days prior to enrollment
12. Evidence of myxoma, left atrial thrombus or intracardiac mural thrombus++
13. Previous cardiac surgery (i.e. ventriculotomy, atriotomy, CABG, PTCA, PCI, coronary stenting procedures) ≤ 90 days prior to enrollment.
14. Severe valvular disease, including mechanical prosthetic mitral or tricuspid heart valves (patients with successful mitral valve repair allowed - annular ring constitutes repair);
15. Any prior history of documented cerebral infarct, TIA or systemic embolism \[excluding a post-operative deep vein thrombosis (DVT)\] \<180 days prior to enrollment
16. Moderate or severe mitral stenosis (severity assessed on the most recent TTE ≤180 days prior to enrollment. Defined as pulmonary artery systolic pressure \>30 mmHg)
17. Presence of left atrial appendage closure device
18. Interatrial baffle, closure device, patch, or patent foramen ovale (PFO) occluder
19. Subjects who, in the judgment of the investigator, have a life expectancy of less than two (2) years
20. Women of childbearing potential who are, or plan to become, pregnant during the time of the study (method of assessment upon investigator's discretion)
21. Amiodarone use within 60 days prior to enrollment
22. Any carotid stenting or endarterectomy
23. Stage 3B renal disease or higher (estimated glomerular filtration rate, eGFR \<45 mL/min)
24. Known coagulopathy disorder (e.g. von Willebrand's disease, hemophilia)
25. Any known contraindication to an AF ablation
26. Any known contraindication for anticoagulation (e.g. patients unable to receive heparin or an acceptable alternative to achieve adequate anticoagulation)
27. Vena cava embolic protection filter devices and/or known femoral thrombus that prevents catheter insertion from the femoral approach
28. Known sensitivity to contrast media (if needed during the procedure) that cannot be controlled with pre-medication
29. Rheumatic Heart Disease
30. Presence of intramural thrombus, tumor or other abnormality that precludes vascular access, or manipulation of the catheter
31. Subjects unable or unwilling to complete follow-up visits and examinations for the duration of the clinical study
32. Subjects who are currently enrolled in another investigational study or registry that would directly interfere with the current study, except when the subject is participating in a mandatory governmental registry, or a purely observational registry with no associated treatments; each instance must be brought to the attention of the sponsor to determine eligibility.


* The absence of thrombus must be confirmed by means of a trans-esophageal echocardiogram (TEE) within 48 hours prior to the procedure or Intracardiac Echography (ICE) during the procedure in subjects not adequately anticoagulated per Section 10.4.2. If a thrombus is observed, the subject no longer meets eligibility criteria and should be considered "Consent Ineligible".
