Outcome Measures

Primary Outcomes (2)

  • Percentage of Subjects With Complete Bidirectional Conduction Block.

    Acute success is defined as the confirmation of complete bidirectional conduction block across the subeustachian (cavo-tricuspid) isthmus. The percentage of subjects with confirmed conduction block will serve as the outcome measure.

    During the procedure

  • Percentage of Subjects Experiencing Cardiovascular Specific Adverse Events (CSAE) Within Seven (7) Days of the Ablation Procedure.

    The cardiovascular specific adverse event (CSAE) rate is the primary safety enpoint for the study. A CSAE is an event which occurs within the first week (7 days) following use of the device and is one of the following cardiac specific adverse events: cardiac perforation, pericardial effusion, pulmonary embolus, complete heart block, stroke, acute myocardial infarction, and death.

Eligibility Criteria

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

You may qualify if:

  • Two symptomatic episodes of typical atrial flutter (or chronic atrial flutter) during the one-year period prior to enrollment. This may include typical AFL occurring while receiving anti-arrhythmic drug (AAD) therapy for non-AFL tachyarrhythmia, including atrial fibrillation.
  • At least one episode of typical (clockwise or counterclockwise) atrial flutter documented by 12 lead electrocardiogram (ECG), Holter monitor, transtelephonic event monitor, telemetry strip, or implanted device within 6 months prior to enrollment.
  • years of age or older
  • Informed consent

You may not qualify if:

  • Intracardiac thrombus
  • Uncontrolled heart failure, or New York Heart Association (NYHA) class III or IV heart failure
  • Women who are pregnant
  • Cardiac surgery (ventriculotomy or atriotomy) within the past two months
  • Intra-atrial thrombus, tumor, or other abnormality that precludes catheter introduction and placement
  • Unstable angina or acute myocardial infarction within 3 months
  • Awaiting cardiac transplantation
  • Heart disease in which corrective surgery is anticipated within 6 months
  • Presence of condition that precludes appropriate vascular access
  • Enrolled in any investigational device exemption (IDE) investigating study for a device or drug
  • High risk for non-compliance with the protocol (e.g., inaccessible for follow-up by the investigator or patient's physician)
  • Radio frequency (RF) ablation for typical atrial flutter within the past 2 months
