Key result
MRI appears safe in patients with temporary external pacemakers with 0 device-related malfunctions observed.
Why the study?
The safety and feasibility of MRI in patients with transvenous temporary external pacemakers and the impact of artefacts on cardiac MRI image quality were not well described.
Does magnetic resonance imaging cause device-related malfunction or image artefacts in patients with temporary external pacemakers?
Observational (n=44)
No
Does magnetic resonance imaging cause device-related malfunction or image artefacts in patients with temporary external pacemakers?
MRI appears safe and feasible in patients with temporary external pacemakers established with a regular MRI-conditional pacemaker and a standard active fixation lead.
May support MRI consideration in select patients with temporary external pacemakers; hypothesis-generating and requires larger prospective confirmation.

Fyenbo et al. (2022) conducted an observational in Temporary external pacemakers (n=44). Magnetic resonance imaging (MRI) was evaluated on Device-related malfunction, arrhythmia, or artefacts compromising diagnostic image quality. Magnetic resonance imaging was safe in 44 patients with temporary external pacemakers, with 0 device-related malfunctions, arrhythmias, or image-compromising artefacts observed.
