About

The objective of this post-market, clinical follow up (PMCF) study, is to confirm the long-term safety of the Tendril STS and Isoflex leads, implanted with the Assurity MRI™ or Endurity MRI™ pacemakers, in patients undergoing a clinically indicated 3T MRI (3 Tesla Magnetic Resonance Imaging) scan.

Full description

This prospective, non-randomized, observational study will be conducted at 35 centers worldwide where the study devices have 3T MR Conditional labeling; up to 110 patients will be enrolled, and will satisfy the recent PMCF requirement to maintain the CE mark.

Enrollment: 3 patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

1. Subject must be willing and able to provide informed consent for study participation (legal guardian or legally authorized representative is NOT acceptable).

3. Capture threshold is stable and < 2.5V @ 0.5ms at the time of enrollment.
4. Subject is clinically indicated for a 3T MRI scan without sedation NOTE: Antianxiety agents (e.g. minor tranquilizers, etc.) may be used as long as the patient can communicate with site personnel during the MRI scan
5. Subject is willing and able to comply with the prescribed follow-up tests and schedule of evaluations.

Exclusion criteria
