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

  • Age 18 years or older
  • Signed Patient Informed Consent Form
  • Able and willing to comply with all pre-, post-, and follow-up testing and requirements
  • Failure of at least one anti-arrhythmic medication (AAD) for paroxysmal atrial fibrillation* [class I or III, or AV nodal blocking agents such as beta blockers (BB) and calcium channel blockers (CCB)] as evidenced by recurrent symptomatic paroxysmal atrial fibrillation*, or intolerable side effects due to AAD

  • Subjects with symptomatic paroxysmal atrial fibrillation (PAF)*

    • PAF is defined as recurrent atrial fibrillation (AF) that terminates spontaneously within seven days.

Exclusion Criteria:

  • Atrial fibrillation (AF) secondary to electrolyte imbalance, thyroid disease, or reversible or non-cardiac cause
  • Previous ablation for AF
  • History of any valvular cardiac surgical procedure
  • Coronary artery bypass grafting (CABG) procedure within the last six months

  • Significant pulmonary disease, (e.g. restrictive pulmonary disease, constrictive or chronic obstructive pulmonary disease) or any other disease or malfunction of the lungs or respiratory system that produces chronic symptoms
  • Significant congenital anomaly or medical problem that in the opinion of the investigator would preclude enrollment in this study
  • Women who are pregnant (by history of menstrual period or pregnancy test if the history is considered unreliable)
  • Acute illness or active systemic infection or sepsis
  • Unstable angina
  • Myocardial infarction within the previous two months
  • Left ventricular ejection fraction (LVEF) <40% as determined by pre-procedure transthoracic echocardiogram (TTE)

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Confirmation of Entrance Block in the Pulmonary Veins
Time Frame: 20 minutes after initial isolation
20 minutes after initial isolation
Incidence of Adverse Events Included in the Pre-specified Composite
Time Frame: 7 days
Atrial perforation, atrio-esophageal fistula, cardiac tamponade, cerebrovascular accident, death, diaphragmatic paralysis, hospitalization, myocardial infarction, pericaridal effusion, pericarditis, pulumonary edema, pulmonary vein stenosis, thromboembolism, transient ischemic attack, and vascular access complications.
7 days
Incidence of Adverse Events Included in the Pre-specified Composite.
Time Frame: 12 months
12 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Documented (> 30 Seconds) Asymptomatic Episodes of Atrial Fibrillation (AF), Atrial Flutter (AFL), or Atrial Tachicardia (AT) After the Blanking Period
Time Frame: 12 months

Study record dates

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.
February 1, 2010

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.
