Future Cardia™ Insertable Cardiac Monitor in Subjects With Paroxysmal Atrial Fibrillation (First-in-Human Study)

Inclusion Criteria:

1. Adult patients (≥18 years old and <75 years old)

2. Paroxysmal AF, defined as AF that terminates spontaneously or with interventionwithin 7 days of onset (ESC 2020 guidelines). In order to be included, patients mustpresent one of the following conditions:

3. paroxysmal AF patients that are candidates for AF ablation;

4. patients hospitalized for symptomatic AF, who failed to convert in theemergency room (ER):

5. outpatients who require treatment with anti-arrhythmic drugs (AAD) (mostlypropafenone or flecainide; more rarely sotalol or amiodaron are given for PAF).

6. Patient is willing and able to provide written informed consent.

7. Patient is willing and able to comply with the protocol, including follow-up visitsand data transmissions.

Exclusion Criteria:

1. Patient who is scheduled to have MRI or is likely to require MR screening. TheFuture Cardia implant is not compatible with MRI.

2. Currently indicated for or implanted with a cardiovascular implantable electronicdevice (CIED) (e.g., ICM or ILR, pacemaker, ICD, CRT-D or CRT-P device) orhemodynamic monitoring system.

3. Compromised immune system or at high risk of developing an infection.

4. Active systemic infection or history of any infection within the last 30 days.

5. Subjects who are female must:

6. have a negative pregnancy test by β-hCG blood test.

7. not breastfeeding

8. either be surgically sterile, postmenopausal (cessation of menses for at least 1 year), or if they have childbearing potential, agree to use a medicallyaccepted, highly effective method of contraception during the entire durationof the study.

9. Subject is currently enrolled in another investigational study.

10. Any condition or abnormality (including clinical laboratory, physical examination,or vital sign abnormalities), current or past, that, in the opinion of theInvestigator, would compromise the efficacy evaluation, safety of the patient, orwould interfere with or complicate study procedures or assessments.

13. Subject is unwilling or unable to comply with the study procedures.

14. Subject is legally incapacitated and unable to provide written informed consent. Exclusion criteria for the study procedure:

15. Patient with abnormal thoracic anatomy or scar tissue at the implant site that mayadversely impact the insertion procedure.

16. For patients currently taking warfarin at the time of insertion, most recent INRvalue (within 7 days) is less than 3.5 for an acceptable risk of bleeding.
