Trial Summary

What is the purpose of this trial?

The purpose of this study is to determine the safety and efficacy of MRI scanning in patients with fractured or abandoned endocardial leads. Specifically, the investigators aim to provide community-acquired data that can be used in Medicare and Medicaid coverage determinations and to investigate whether patients with fractured or abandoned leads can safely be scanned using an MRI and to evaluate the impact of MRI availability on patient care in this population. This study also aims to validate similar studies conducted by Mayo Clinic, the Hospital of the University of Pennsylvania and Johns Hopkins Medicine that employ MRI in the abandoned lead patient population.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications.

What data supports the effectiveness of the treatment MRI for pacemaker lead fracture?

Recent studies show that MRI can be safely performed on patients with pacemakers if specific precautions are taken, such as device reprogramming and careful monitoring. Advances in technology have led to the development of 'MR-conditional' devices, which are designed to be safe in the MRI environment, allowing more patients to undergo MRI without significant risks.12345

Is MRI safe for patients with pacemakers?

MRI can be risky for patients with pacemakers due to potential heating of the pacemaker lead and electromagnetic interference. However, some newer pacemaker systems, like the Medtronic EnRhythm MRI SureScan, have been designed and tested for safer use in MRI environments, although they are not yet considered completely 'MRI-safe' or 'MRI-compatible' by the FDA.678910

How is MRI treatment unique for patients with pacemaker lead fractures?

MRI is unique for patients with pacemaker lead fractures because it allows for detailed imaging without surgery, but it requires special 'MR-conditional' pacemakers designed to be safe in the MRI environment. This is different from traditional treatments that might avoid MRI due to safety concerns with standard pacemakers.146711

Eligibility Criteria

This trial is for English or Spanish speaking adults with a broken or unused heart device lead who need an MRI scan. It's not for those unsuitable for MRI due to other reasons, or anyone under 18.

Inclusion Criteria

I have a heart device and need an MRI despite having a non-working lead.
I can speak and understand English or Spanish and can sign the consent form.

Exclusion Criteria

Patients who complete the MRI standard screening form and are deemed inappropriate for MRI for any reason other than abandoned or fractured endocardial, or epicardial lead.
I am under 18 years old.

Findings from Research

Recent advancements in understanding the risks and mechanisms of MRI interactions with cardiovascular devices have made it safer for patients with pacemakers and ICDs to undergo MRI scans.
The introduction of 'MR-conditional' devices has become the new standard of care, allowing for routine MRI use in these patients, although specific precautions must still be followed to ensure safety.
Magnetic resonance imaging safety in pacemaker and implantable cardioverter defibrillator patients: how far have we come?Nordbeck, P., Ertl, G., Ritter, O.[2018]
Recent studies indicate that patients with pacemakers or implantable cardioverter-defibrillators can safely undergo MRI under specific monitoring and reprogramming conditions, challenging the previous belief that these devices were absolute contraindications.
The involvement of device manufacturers in developing MRI-safe devices may expand the future use of MRI in patients with implanted cardiac devices, enhancing patient management options.

In a study of 36 patients with MR conditional pacemakers, undergoing heart MRI at 1.5 Tesla was found to be safe, with no adverse events reported during or after the procedure.
While some patients experienced increases in pacing capture thresholds (PCT) after the MRI, these changes were not clinically significant, indicating that the MRI did not adversely affect the function of the pacemaker system.
