Multi-electrode PulmonarY Vein Isolation Versus Single Tip Wide Area Catheter Ablation for Paroxysmal Atrial Fibrillation (PAF) (MYSTIC-PAF)

May 27, 2015 updated by: L.V.A. Boersma

Multi-electrode PulmonarY Vein Isolation Versus Single Tip Wide Area Catheter Ablation for PAF a Randomized Multinational Multicenter Trial

The MYSTIC_PAF trial investigates the differences between treatment with a single-tip catheter against a multielectrode catheter in cardiac ablation procedures in patients with paroxysmal atrial fibrillation.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

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

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  1. History of symptomatic paroxysmal atrial fibrillation defined as:

    • Self-terminating AF with episodes lasting no more than seven consecutive days before spontaneous conversion back to sinus rhythm
    • Documentation of one or more events with PAF tracings by ECG, event recordings, pacemaker strips or monitor rhythm strips within the past year

    • AF symptoms defined as the manifestation of any of the following:

      • Palpitations
      • Fatigue
      • Exertional dyspnea
      • Effort intolerance
  2. Age between 18 and 70
  3. Willingness, ability and commitment to participate in baseline and follow-up evaluations for the full length of the study

Exclusion Criteria:

  1. Structural heart disease of clinical significance including:

    • Previous cardiac surgery (excluding CABG)
    • Symptoms of congestive heart failure including, but not limited to, NYHA Class III or IV CHF and/or documented ejection fraction < 40% measured by acceptable cardiac testing
    • Left atrial diameter of > 50mm as measured in the parasternal long axis on transthoracic echocardiogram
    • Stable/unstable angina or ongoing myocardial ischemia
    • Myocardial infarction (MI) within three months of enrollment
    • Aortic or mitral valve disease > Grade II
    • Congenital heart disease (not including ASD or PFO without a right to left shunt) where the underlying abnormality increases the risk of an ablative procedure
    • Prior ASD or PFO closure with a device using a percutaneous approach
    • Hypertrophic cardiomyopathy (LV wall thickness > 1.5 cm)
    • Pulmonary hypertension (mean or systolic PA pressure >50mm Hg on Doppler echo
  2. Prior ablation for arrhythmias other than AF within the past three months
  3. Prior left sided AF ablation
  4. Enrollment in any other ongoing arrhythmia study protocol Any ventricular tachyarrhythmias currently being treated where the arrhythmia or the management may interfere with this study

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
January 1, 2011

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. 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.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
