Detailed Description

A prospective, single-arm, multi-center, multi-national, non-randomized, post-market study designed to provide clinical data regarding the use of the AcQMap High Resolution Imaging and Mapping System during an atrial fibrillation retreatment ablation procedure. The patient population includes men and women, eighteen (18) years of age or older. The treatment plan must include evaluation and ablation (as indicated) of pulmonary vein reconnections plus AcQMap guided non-PV substrate ablation. Subject assessments will occur at screening, procedure, hospital discharge, 3-, 6-, and 12-months. (CLP-AF-004 [EU])

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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

14 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Inclusion Criteria:

  • Male or female eighteen (18) years of age or older
  • Currently scheduled for a repeat endocardial ablation of AF where the index atrial fibrillation ablation procedure was completed ≤ twenty-four (24) months prior to enrollment and the subject has demonstrated at least one episode of post-ablation non-self-terminating AF

Exclusion Criteria:

  • No more than two (2) previous left-atrial ablations
  • Structural heart disease or implanted cardiac devices

For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
