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.

Detailed Description

The study's intent is to generate long-term real-world data on the safety, performance, and clinical benefits of the Assert-IQTM ICM device system. This clinical investigation is sponsored by Abbott Medical.

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

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

Subjects who are diagnosed with symptomatic, drug-refractory paroxysmal or persistent AF, and are scheduled to receive an Assert-IQTM ICM device

Description

Inclusion Criteria:

Patients must meet ALL study inclusion criteria to participate in the study.

  1. Have an approved indication AND are scheduled to receive an Assert-IQTM ICM device prior to enrollment in the study.
  2. Diagnosed with symptomatic, drug-refractory paroxysmal or persistent AF prior to enrollment in the study and scheduled to undergo a first-time atrial fibrillation ablation.
  3. Have a cellular phone or the ability or willing to use a mobile transmitter that is compatible with the myMerlin™ App and able to communicate with the Assert-IQTM ICM device. If a subject doesn't have a cell phone or loses their cell phone, then the site can provide a mobile transmitter to the subject. The study will not provide cell phones.
  4. Are 18 years of age or older, or of legal age to give informed consent specific to state and national law.
  5. Have the ability to provide informed consent for study participation and be willing and able to comply with the prescribed follow-up tests and schedule of evaluations.

Exclusion Criteria:

If ANY study exclusion criteria are met, the patient is excluded from the study and cannot be enrolled (recruitment failure).

  1. Subject is currently participating in another clinical investigation that could confound the results of this study, without documented pre-approval from Abbott.
  2. Subject is implanted with a cardiac implantable electronic device (CIED) with pacing capability.
  3. Have a life expectancy of less than 1 year due to any condition.

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
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.
Subjects successfully implanted with an Abbott Assert-IQ ICM device
Holter monitoring in subjects successfully implanted with an Abbott Assert-IQ ICM device
Device: Holter monitoring in patients who have been successfully implanted with an Abbott Assert-IQ ICM device
All enrolled subjects who meet eligibility criteria will undergo an attempted implant within 30 days of consent. After successful device implant, subjects will be followed at 1 and 12 months. Subjects will be fitted with a Holter monitor during the 1m follow-up visit and will complete a minimum of 72 hours and maximum of up to 7 days of Holter monitoring.

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
Episode-based AF detection performance metrics
Time Frame: Holter monitor worn by the subjects over a minimum 72-hour and up to 7 days period. An AF episode is defined as AF has greater or equal to 2 minutes (≥2 minutes) in duration.
Episode-based AF detection performance metrics of the Assert-IQTM ICM device compared to that of simultaneous Holter monitoring in 150 subjects who had received the Assert-IQTM ICM device as part of their standard of care.
Holter monitor worn by the subjects over a minimum 72-hour and up to 7 days period. An AF episode is defined as AF has greater or equal to 2 minutes (≥2 minutes) in duration.

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.
