Small study tests MRI safety for Mixed-Device heart patients
NCT ID NCT07155135
First seen Jun 26, 2026 · Last updated Jun 26, 2026 · Updated 1 time
Summary
This completed study looked at whether MRI scans are safe for people who have cardiac devices (like pacemakers) made by different manufacturers. Sixteen patients with mixed-manufacturer devices received an MRI, and researchers checked for changes in battery voltage, lead impedance, and lead threshold. The goal was to see if MRI causes any device problems or harms the patient.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- Magnetic resonance imaging (MRI)
- What this could lead to
- If successful, this could show that MRI is safe for patients with mixed-manufacturer cardiac devices, expanding access to this important diagnostic tool.
- What could go wrong
- This is a very small, completed study with only 16 participants. Results may not apply to all device types or patients, and safety risks like device interference remain possible.
