Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Age > or equal to 18 years of age

  • History of non-paroxysmal form of Atrial Fibrillation (AF) as defined by the Heart Rhythm Society/European Heart Rhythm Association/European Cardiac Arrhythmia Society Consensus Statement:

    • Persistent AF shall be defined as continuous AF that is sustained beyond seven days. Episodes of AF in which a decision is made to electrically or pharmacologically cardiovert the patient after greater than or equal to 48 hours of AF but prior to 7 days, should also be classified as persistent AF episodes.
    • Longstanding persistent AF shall be defined as continuous AF of greater than 12 months duration. The performance of a successful cardioversion (sinus rhythm >30 seconds) within 12 months of an ablation procedure with documented early recurrence of AF with 30 days should not alter the classification of AF as longstanding persistent.
  • Subject is scheduled to undergo elective open cardiac surgical procedure(s) to be performed on cardiopulmonary bypass for one or more of the following: Coronary Artery Bypass Grafting, Mitral valve repair or replacement, Aortic valve repair or replacement, Tricuspid valve repair or replacement. In conjunction with these procedure patent foramen ovale (PFO) or atrial septal defect (ASD) repair are allowed.
  • The patient (or their legally authorized representative) agrees to participate in this study by singing the Institutional Review Board (IRB) approved informed consent form.
  • Willing and able to return for scheduled follow up visits.

Exclusion Criteria:

  • Stand along AF without indication(s) for concomitant cardiac surgery.
  • Need for emergent cardiac surgery (i.e., cardiogenic shock).
  • Preoperative need for an intra-aortic balloon pump or intravenous inotropes.
  • Pregnancy or desire to get pregnant for the duration of the study concomitant surgical procedure through the thirty six (36) month follow up period).
  • Enrolled in another clinical trial that could confound the results of this study.

Patients with non-paroxysmal atrial fibrillation (persistent or longstanding persistent)who are scheduled to undergo elective concomitant open, on-pump cardiac surgical procedure and the Maze IV ablation procedure. This single arm registry is designed to monitor the AtriCure Synergy Ablation System for continued safety and efficacy during the peri-procedural and long term phase during commercial use.
Device: Synergy Ablation System

Patient will undergo an elective open cardiac surgical procedure to be performed on cardiopulmonary bypass for one or more of the following:

  • Coronary Artery Bypass Grafting (CABG)
  • Mitral valve repair or replacement
  • Aortic valve repair or replacement
  • Tricuspid valve repair or replacement The aim of the treatment is a complete bi-atrial Maze IV procedure which includes pulmonary vein isolation coupled with lesions made on both the left and right atria.
Other Names:
  • Isolator Synergy Handpieces
  • Isolator Synergy Clamp

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
The Number of Participants Free From Atrial Fibrillation (AF), Atrial Flutter or Atrial Tachycardia While Off Class I and Class III Antiarrhythmic Drugs for at Least 4 Weeks.
Time Frame: 36 months post-operatively
The number of participants free from atrial fibrillation (AF), i.e., episodes lasting >30 continuous seconds duration of either AF, atrial flutter or atrial tachycardia while off Class I and III antiarrythmic drugs for at least 4 weeks as determined by core last assessment of a 48 hour Holter, Zio Patch or Pacemaker Implantation (PPM) interrogation recording performed at a minimum of 36 months postoperatively.
36 months post-operatively

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Secondary Efficacy Outcome
Time Frame: 12, 24, and 36 months post-operatively
The proportion of patients free from AF, regardless of AAD usage (i.e. no episodes lasting > 30 continuous seconds duration of either Atrial Fibrillation, Atrial Flutter or Atrial Tachycardia), as determined by an independent core lab assessment of 48-hour Holter, Zio™ Patch or PPM interrogation recording performed at a minimum of 12,24, and 36 months post-operatively.
12, 24, and 36 months post-operatively

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date.
