September 17, 2018 updated by: Medtronic Cardiac Rhythm and Heart Failure

Evaluate Reduction in Asymptomatic Cerebral Embolism

The purpose of the study is to determine the rate of diffusion weighted (DW)-MRI cerebral lesions following a Pulmonary Vein Ablation Catheter (PVAC) ablation procedure performed using best practices, including optimized procedural techniques and anti-coagulation therapy.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

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

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
60

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

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Other: Ablation
Other: Magnetic Resonance Imaging (MRI)
MRI's will be performed on all subjects at Enrollment and Pre-Discharge (Post Ablation). Subjects with a positive MRI (cerebral lesion) at the Pre-Discharge will undergo an MRI at the 1 month follow-up visit.

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
New Asymptomatic Cerebral Embolic Lesions, Visualized as 'Bright Spots' on Post-ablation MRI.
Time Frame: Within 1-3 days post ablation
An acute embolic lesion is defined as a focal hyper-intense area detected on the diffusion-weighted (DW) sequence, corresponding to a hyper-intense signal intensity in the fluid-attenuated inversion recovery (FLAIR) sequence, and also confirmed by apparent diffusion coefficient (ADC) mapping to rule out a shine-through artifact.
Within 1-3 days post ablation

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
Acute Safety Events
Time Frame: 30 days
Assess the number of procedure or device-related serious adverse events when applying best practices with PVAC.
30 days
Acute Efficacy, as Determined by Complete Pulmonary Vein Isolation (PVI) Per Subject.
Time Frame: Day 1 (End of Procedure)
The number of subjects with pulmonary vein isolation (PVI) at the end of ablation procedure. This will characterize if use of best practices during PVAC ablation negatively affects acute efficacy.
Day 1 (End of Procedure)

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.
