Summary: This clinical investigation is intended to demonstrate the acute safety and effectiveness of ablation with the TactiCath™ Contact Force Ablation Catheter, Sensor Enabled™ (TactiCath SE) for the treatment of drug refractory recurrent symptomatic paroxysmal atrial fibrillation (PAF). This clinical investigation will be conducted under an investigational device exemption (IDE) and is intended to support market approval of the TactiCath SE ablation catheter in the United States. One hundred fifty six (156) subjects will be enrolled at up to 35 investigational sites in the US, Europe, and Australia. This clinical investigation is sponsored by Abbott.
Eligibility:

Inclusion Criteria:

- 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

- Physician's note indicating recurrent self-terminating AF

- One electrocardiographically documented AF episode within 6 months prior to the index ablation procedure

- At least 18 years of age

- Able and willing to comply with all trial requirements

- 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.

- Persistent or long-standing persistent atrial fibrillation (AF)

- Four or more cardioversions in the past 12 months

- Active systemic infection

- Known presence of cardiac thrombus

- Implanted with implantable cardiac defibrillator (ICD)

- Arrhythmia due to reversible causes including thyroid disorders, acute alcohol intoxication, and other major surgical procedures in the preceding 3 months

- Myocardial infarction (MI), acute coronary syndrome, percutaneous coronary intervention (PCI), or valve or coronary bypass grafting surgery within preceding 3 months

- Left atrial diameter > 5.0 cm

- Left ventricular ejection fraction < 35%

- New York Heart Association (NYHA) class III or IV

- Bleeding diathesis or suspected procoagulant state

- Contraindication to long term antithromboembolic therapy

- Presence of any condition that precludes appropriate vascular access

- Renal failure requiring dialysis

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

- 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

- Pregnant or nursing

- Presence of other anatomic or comorbid conditions 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

- 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

- Patient is unlikely to survive the protocol follow up period of 12 months

- Body mass index > 40 kg/m2

- Vulnerable subject
