A Study to Assess the Use of The Sentinel Device During Atrial Fibrillation Ablation

April 12, 2023 updated by: Ammar M. Killu, Mayo Clinic

A Pilot Randomized Study of the Use of The Sentinel Device for Cerebral Protection During Atrial Fibrillation Ablation: MRI Imaging and Laboratory Sub-study

Researchers are determining whether the use of the Sentinel cerebral protection device during atrial fibrillation ablation will affect the occurrence of new cerebral infarcts in brain MRI. We are also studying if laboratory tests can be used to predict the rate of cerebral infarction and microbleeds in patients undergoing atrial fibrillation (AF) ablation procedures with and without use of the Sentinel Device.

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.

Detailed Description

Patients currently participating in the research study titled: "A Pilot Randomized Study of the Use of the Sentinel Device for Cerebral Protection during Atrial Fibrillation Ablation" will be asked to participate in this sub-study to collect additional MRI and laboratory data to support the main study. This study will assess the number, size and volume of new cerebral emboli in protected territories detected using MRI of the brain within 7 days after AF ablation in patients treated with the Sentinel device compared to controls not receiving the Sentinel device, and to assess if change in blood inflammatory markers is associated with silent cerebral lesions.

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

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

Description

Inclusion Criteria:

  • Patients over the age of 18 years undergoing radiofrequency or cryoballoon ablation for AF who provide informed consent will be included

Exclusion Criteria:

  • Severe peripheral arterial disease that precludes deployment of Sentinel device
  • Unable to undergo MRI brain due to the presence of an MRI noncompatible implanted device
  • Unable or unwilling to provide informed consent.
  • Known history of dementia.

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.
