What effect might a malfunctioning non-ferrous leadless pacemaker have during an MRI?

A malfunctioning non-ferrous leadless pacemaker could potentially migrate during an MRI due to the strong magnetic fields generated by the MRI machine. This is particularly relevant for devices that rely on precise positioning within the heart. Even if a pacemaker is non-ferrous, the interaction with the powerful magnetic field can create enough force to shift its position, especially if there is a malfunction affecting its stability or securing mechanisms.

Understanding device performance in an MRI environment is crucial, as this could impact the functionality of the pacing system and pose safety risks to the patient. While it is true that other issues could arise, such as heating effects or noise generation, the concern with migration emphasizes the risks associated with device malfunction rather than normal operational behavior. Each of these considerations is important when evaluating the safety of MRI procedures in patients with implanted devices.
