Summary

This study aimed to see if MRI scans are safe for people with broken or unused wires (leads) from pacemakers or defibrillators. It enrolled 18 participants and monitored for side effects like chest pain or heart rhythm problems. The study was terminated early, so the findings are limited.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

What this could lead to: If successful, this could help doctors safely offer MRI scans to more patients with broken or unused heart device leads.
What could go wrong: The study was terminated early and had only 18 participants, so results are limited and may not apply to everyone. MRI in these patients still carries unknown risks.
