Outcome Measures

Primary Outcomes (4)

  • To define the safety of MPT for the treatment of atrial fibrillation in subjects

    Adverse Events from procedure and 30 day follow up.

    Study procedure and 30 day post procedure

  • Translation

    Explore and enhance MPT parameters delivered in successful cases in a previous Cardialen AF study (CL001 / NCT02257112)

    Study procedure

  • Translation

    Determine MPT parameters relationships at which MPT terminates AF

    Study procedure

  • Translation

    Determine rate of conversion from AF to NSR after MPT delivery

    Study procedure

Study Arms (1)

Multi Pulse Therapy

EXPERIMENTAL

Subjects will have AF induced and the Cardialen External Stimulation System (CESS) device will deliver electrical stimulation to terminate the arrhythmia.

Device: Multi Pulse Therapy

Interventions

The Cardialen External Stimulation System (CESS) is the research delivery system for the proprietary Cardialen MultiPulse Therapy (MPT). The CESS is a custom designed and built research device. It is comprised of off-the-shelf commercial components (power supplies, waveform generators, laptop computer, monitor, rack, ECG system, leads, etc.) combined with a custom electrical circuit board and custom software.

Also known as: Unpinning Termination Therapy, Multi-stage therapy, Multi-stage electrotherapy, MultiPulse Therapy

Eligibility Criteria

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

You may qualify if:

  • Male or female between 18 and 80 years of age
  • Willing and able to comply with the study protocol, provide a written informed consent
  • Currently indicated for atrial catheter ablation due to paroxysmal or early persistent atrial fibrillation
  • Current treatment and compliance with standard anticoagulation regimen, including uninterrupted OAC, with acceptable coagulation status, as determined by globally accepted risk stratification (CHA2DS2-VASc score) and the Principal Investigator

You may not qualify if:

  • Life expectancy of 1 year or less
  • AF due to reversible causes (e.g., hyperthyroidism, valve disease)
  • History of DC Cardioversion which failed to convert to AF to Normal Sinus Rhythm
  • Currently in AF for more than 3 months continuously
  • Chronic, long-standing persistent, or permanent atrial fibrillation
  • Allergy or contraindication to anticoagulation therapy
  • Presence of intracardiac thrombus (confirmed with TEE or ICE)
  • Existing Left Atrial Appendage closure device
  • Severely Dilated Left Atrium \>5cm
  • LVEF\<20%
  • NYHA Class IV heart failure at the time of enrollment
  • History of embolic stroke, Transient Ischemic Attack (TIA) or other thromboembolic event within the preceding 3 months.
  • Known hyper-coagulable state that increases risk of thrombus
  • History of myocardial infarction or coronary revascularization within the preceding 3 months.
  • History of sustained ventricular arrhythmia or cardiac arrest
  • +19 more criteria
