Who cannot take part
Copied verbatim from ClinicalTrials.gov and grouped by topic. Only the trial team decides who can take part.
Prior treatment
- Atrial exclusions - any of the following atrial conditions:
- Left atrial anteroposterior diameter ≥ 5.5 cm, or if LA diameter is not available, LA non-indexed volume \> 100 mL. If both values are available, only the LA diameter will be used to confirm eligibility.

- Cardiovascular Conditions - Any of the following cardiovascular conditions:
- History of sustained ventricular tachycardia (VT) or any ventricular fibrillation (VF)
- Atrial fibrillation that is secondary to electrolyte imbalance, thyroid disease, alcohol, or other reversible/non-cardiac causes
- Cardiac Devices and Implants:
- Current or anticipated pacemaker, implantable cardioverter-defibrillator or cardiac resynchronization therapy devices.
- Interatrial baffle, patent foramen ovale, or atrial septal defect closure device or patch.

Lab values
- Baseline Conditions - Any of the following conditions at Baseline:
- Heart failure - Heart failure associated with NYHA Class III or IV

- Hematologic Condition: Known coagulopathy or bleeding disorder
- Anticoagulation Contraindication: Contraindication to, or unwillingness to use, systemic anticoagulation, or acceptable alternatives, pre-, intra- and post-procedure to achieve adequate anticoagulation
- Pregnancy - Women who are confirmed to be pregnant or lactating at the time of the ablation procedure
- Pulmonary Disease - Severe lung disease, severe pulmonary hypertension, or any lung disease involving abnormal blood gases or requiring supplemental oxygen
- Malignancy - Active malignancy (other than non-melanoma skin cancers)
- Gastrointestinal - Clinically significant gastrointestinal problems involving the esophagus or stomach, including severe or erosive esophagitis, uncontrolled gastric reflux, gastroparesis, esophageal candidiasis or active gastroduodenal ulceration
- Infection - Known active systemic infection
- Sleep Apnea - Untreated diagnosed obstructive sleep apnea with apnea-hypopnea index classification of severe (\> 30 events per hour) as per the guidelines
- Life Expectancy - Predicted life expectancy of less than one (1) year per investigator medical judgment
- Concurrent Enrollment - 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
- Medical History - Any of the following conditions in the Medical History
- Transplantation - Solid organ or hematologic transplant, or currently being evaluated for a transplant
