Hypothesis
Is the AB5000 Ventricular Assist Device safe for MRI at 3-Tesla?
Conclusion
Patients with the AB5000 VAD can safely undergo MRI at 3-Tesla or less.
Supporting Evidence
- The device showed minor magnetic field interactions that won't cause movement.
- Heating was not excessive, with the highest temperature change being +0.8°C.
- Artifacts may affect diagnostic imaging if the area of interest is near the implanted device.
Takeaway
This study checked if a heart device can be safely scanned with an MRI machine. It found that it is safe to do so.
Methodology
The study evaluated the AB5000 VAD for magnetic field interactions, heating, and artifacts using a 3-Tesla MRI system.
Limitations
The prototype Nitinol cannula is not commercially available yet.
