Outcome Measures

Primary Outcomes (1)

  • Number of Participants With Freedom From Device/Procedure Related Major Adverse Events (MAEs)

    MAEs inlcude: death, myocardial infarction, cardiac perforation/tamponade, cerebral infarct, or systemic embolism, Major bleeding requiring transfusion of blood products, Mitral or tricuspid valve damage, Symptomatic pulmonary vein (PV) stenosis, Asymptomatic PV stenosis ≥ 70%, Permanent phrenic nerve injury, Access site complications requiring pharmacological or surgical intervention, Atrio-esophageal fistula, Pericarditis, Heart block requiring a permanent pacemaker, Vagal nerve injury leading to gastroparesis, Other serious adverse device effects (SADEs), including transient ischemic attack (TIAs), adjudicated as "probably or definitely related" to the AcQMap System

    6 Months

Secondary Outcomes (1)

  • Number of Participants Who Experienced at Least One procedure and device related Serious Adverse Events.serious adverse device effects (SADEs), and all unanticipated device effects (UADEs)

    6 Months

Other Outcomes (1)

  • Number of subjects who are free from AF/AT/AFL (following a 90-day blanking period)

    12 Months

Study Arms (1)

Non-randomized

OTHER

All subjects with de novo ablation procedure for an atrial arrhythmia using the AcQMap System.

Device: AcQMap High Resolution Imaging and Mapping System

Interventions

Evaluate the safety and effectiveness of the AcQMap System in mapping atrial arrhythmias when a specific procedure work flow is followed.

Non-randomized

Eligibility Criteria

Age18 Years - 80 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Male or female ≥ 18 years of age at the time of consent
  • Clinically indicated and scheduled for a de novo catheter ablation of a complex left atrial arrhythmia including AF/AT/AFL
  • Willing and able to provide written informed consent to participate in the study and agree to comply with all follow-up visits and evaluations for the duration of the study.

You may not qualify if:

  • In the opinion of the investigator, any contraindication to the planned atrial ablation, including anticoagulation contraindications, renal failure, or sepsis.
  • Atrial arrhythmias secondary to electrolyte imbalance, thyroid disease, or any other reversible or non-cardiac cause.
  • Any DCCV within 60-days of the index procedure where sinus rhythm was not maintained for at least 60-minutes.
  • Any cardiac defibrillator (ICD) or pacemaker implanted within 8-weeks prior to the ablation procedure.
  • History of previous left atrial ablation (including surgical treatment) for AF/AT/AFL.
  • Structural heart disease or cardiac history including:
  • Left ventricular ejection fraction (LVEF) \< 35% based on a 2-d transthoracic echocardiogram (TTE) within the previous 180-days prior to enrollment.
  • Left atrial size \> 60 mm (parasternal long-axis view) based on 2-d TTE within the previous 180-days prior to enrollment.
  • Prior history of New York Heart Association (NYHA) Class IV heart failure.
  • Any evidence of NYHA Class III heart failure in the previous 3-months prior to enrollment.
  • Unstable angina or ongoing myocardial ischemia.
  • Myocardial infarction (STEMI) within the previous 180-days (sub-endocardial infarct within previous 90-days) prior to enrollment.
  • Moderate or severe valvular heart disease (stenosis or regurgitation).
  • Presence of a left atrial appendage occlusion device.
  • Body Mass Index (BMI) \> 40kg/m2
  • +4 more criteria
