Clinical Evaluation of Therapy™ Cool Path™ Duo Cardiac Ablation System for the Treatment of Typical Atrial Flutter (AFL)
United States, Canada188 participantsStarted 2009-10
Plain-language summary
The purpose of this study is to demonstrate that ablation with the Therapy™ Cool Path™ Duo cardiac ablation system can eliminate typical atrial flutter and that its use does not result in an unacceptable risk of serious adverse events (SAE's).

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* A signed written Informed Consent
* Presence of typical atrial flutter (cavotricuspid isthmus dependent)
* If subjects are receiving antiarrhythmic drug therapy (Class I or Class III AAD)for an arrhythmia other than typical atrial flutter, then the subject needs to be controlled on their medication for at least 3 months. If the subject had typical atrial flutter before starting the AAD(s) (Class I or Class III) and then subsequently had another arrhythmia (i.e. atrial fibrillation), then the 3 month AAD criteria will not apply.
* One documented occurrence of the study arrhythmia documented by ECG, Holter, telemetry strip, or transtelephonic monitor within the past 6 months
* In good physical health
* 18 years of age or older
* Agree to comply with follow-up visits and evaluation
Exclusion Criteria:
* Prior typical atrial flutter ablation treatment
* Pregnancy
* Atypical flutter or scar flutter(non-isthmus dependent)
* Significant coronary heart disease or heart failure; that is unstable angina pectoris and/or uncontrolled congestive heart failure (NYHA Class III or IV) at the time of enrollment
* A recent myocardial infarction within 3 months of the intended procedure date
* Permanent coronary sinus pacing lead
* Tricuspid valvular disease requiring surgery and/or a prosthetic tricuspid heart valve (i.e. significant)
* Evidence of intracardiac thrombus or a history of clotting disorders
* Participation in another investigational study
* Cardiac surger…
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Primary Safety- Incidence of Intra Procedural Serious Cardiac Adverse Events Occuring Within 7 Days of Post-procedure, Regardless of Whether a Determination Can be Made Regarding Device Relatedness.
Timeframe: 7 days
2
Primary Efficacy- Bidirectional Block in the Cavo-tricuspid Isthmus and Non-inducibility of Typical Atrial Flutter at Least 30 Minutes Following the Last RF Ablation With the Cool Path Duo Ablation Catheter System is Obtained.
