Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 to 75 years
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Adult patients (≥18 years old and <75 years old)
  • Paroxysmal AF, defined as AF that terminates spontaneously or with intervention within 7 days of onset (ESC 2020 guidelines). In order to be included, patients must present one of the following conditions:
  • paroxysmal AF patients that are candidates for AF ablation;
  • patients hospitalized for symptomatic AF, who failed to convert in the emergency room (ER):
  • outpatients who require treatment with anti-arrhythmic drugs (AAD) (mostly propafenone or flecainide; more rarely sotalol or amiodaron are given for PAF).
  • Patient is willing and able to provide written informed consent.
  • Patient is willing and able to comply with the protocol, including follow-up visits and data transmissions.

Who cannot join

  • Patient who is scheduled to have MRI or is likely to require MR screening. The Future Cardia implant is not compatible with MRI.
  • Currently indicated for or implanted with a cardiovascular implantable electronic device (CIED) (e.g., ICM or ILR, pacemaker, ICD, CRT-D or CRT-P device) or hemodynamic monitoring system.
  • Compromised immune system or at high risk of developing an infection.
  • Active systemic infection or history of any infection within the last 30 days.
  • Subjects who are female must:
  • have a negative pregnancy test by β-hCG blood test.
Show all 16Show fewer
  • not breastfeeding
  • either be surgically sterile, postmenopausal (cessation of menses for at least 1 year), or if they have childbearing potential, agree to use a medically accepted, highly effective method of contraception during the entire duration of the study.
  • Subject is currently enrolled in another investigational study.
  • Any condition or abnormality (including clinical laboratory, physical examination, or vital sign abnormalities), current or past, that, in the opinion of the Investigator, would compromise the efficacy evaluation, safety of the patient, or would interfere with or complicate study procedures or assessments.
  • Any concomitant condition which, in the opinion of the investigator, would not allow safe participation in the study (e.g., drug addiction, alcohol abuse, emotional/psychological diagnosis).
  • Obesity, Class 2 (BMI ≥ 35-40) or Class 3 (BMI ≥ 40).
  • Subject is unwilling or unable to comply with the study procedures.
  • Subject is legally incapacitated and unable to provide written informed consent.
  • Patient with abnormal thoracic anatomy or scar tissue at the implant site that may adversely impact the insertion procedure.
  • For patients currently taking warfarin at the time of insertion, most recent INR value (within 7 days) is less than 3.5 for an acceptable risk of bleeding.

About this study

Official title: Clinical Investigation of the Future Cardia™ Insertable Cardiac Monitor in Subjects With Paroxysmal Atrial Fibrillation Voice Of the Heart Trial (First-in-Human Study)

This study is a first-in-human, prospective, multi-center, pre-market single-arm clinical trial to evaluate the Future Cardia™ ICM.

    Duration of Insertion Procedure in minutes (min).

    Measured: up to 24 weeks

  5. Characterization of Explant Procedure - Device removal: Removal Success

    Removal Success (Yes/No)

    Measured: up to 24 weeks

  6. Characterization of Explant Procedure - Device removal: Incision Size

    Incision Size in millimeters (mm)

    Measured: up to 24 weeks

  7. Characterization of Explant Procedure - Device removal: Duration of explant procedure

    Duration of explant procedure in minutes (min).

    Measured: up to 24 weeks

  8. Device and Procedural Safety over a period of 180 days

    1. Number of Serious Adverse Events (SAE) related to the Device or insertion procedure.
    2.

Questions about this trial

What is this clinical trial studying?

A study testing Future Cardia™ Insertable Cardiac Monitoring (ICM) System in people with Arrhythmias, Cardiac and Atrial Fibrillation, run by Future Cardia, Inc at 1 site in Croatia.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 16 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: under way, not looking for participants, as of the sponsor's last update on 8 Aug 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Croatia. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Characterization of Insertion Procedure - Implantation: Insertion Success (time frame: up to 24 weeks). The study lists 9 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Aug 2025.
