NCT01408485

Brief Summary

To demonstrate that ablation with the Therapy™ Cool Flex™ Irrigated Ablation System is effective in the treatment of typical atrial flutter (cavo-tricuspid dependent) and that its use does not result in an unacceptable risk of intra-procedural, serious cardiac adverse events.

Outcome Measures

Primary Outcomes (2)

  • Primary Safety: Incidence of Composite, Serious Adverse Events Within 7 Days Post-Procedure

    Primary safety is defined as the incidence of composite, serious adverse events within 7 days post-procedure, regardless of whether a determination can be made regarding device relatedness.

    7 days

  • Primary Efficacy

    Primary efficacy or acute success is defined as achievement of bi-directional block in the cavo-tricuspid isthmus and non-inducibility of typical atrial flutter at least 30 minutes following the last RF ablation with the investigational system.

    30 minutes

Secondary Outcomes (1)

  • Secondary Efficacy

    3 months

Study Arms (1)

Treatment Arm

EXPERIMENTAL

Radio-frequency cardiac ablation for treatment of isthmus-dependant atrial flutter using the Therapy™ Cool Flex™ Irrigated Ablation System

Device: Therapy™ Cool Flex™ Irrigated Ablation System

Interventions

The investigational components of the Therapy™ Cool Flex™ Irrigated Ablation System consist of: * Therapy™ Cool Flex™ 4mm Irrigated Ablation Catheter * IBI 1500T9 V1.43 RF Generator

Treatment Arm

Eligibility Criteria

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

You may qualify if:

  • A signed written Informed Consent
  • Presence of typical atrial flutter (cavo-tricuspid isthmus dependent)
  • If subjects are receiving anti-arrhythmic 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
  • years of age or older
  • Agree to comply with follow-up visits and evaluation

You may not qualify if:

  • 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
  • Clinically significant Tricuspid valvular disease requiring surgery and/or a prosthetic tricuspid heart valve
  • Evidence of intra-cardiac thrombus or a history of clotting disorders
  • Participation in another investigational study
  • Cardiac surgery within 1 month prior to the intended procedure date
  • Allergy or contraindication to Heparin
