Treatment and study plan

Primary outcomes

Proportion of ICD/CRT-D subjects with a ≥ 5 second delay in post-MRI VF detection.

Time frame: Up to 5 years post-approval

Primary objectives will be analyzed once 25 subjects implanted with the ProMRI ICD system have been identified with a documented true VF episode post-MRI.
Proportion of LV pacing leads with a LV pacing threshold increase > 1V between pre-MRI and one-month post-MRI.

Time frame: Up to 5 years post-approval

Secondary outcomes

Workflow compliance following MR exposure

Time frame: Up to 5 years post-approval

Proportion of subjects with appropriate restoration of tachycardia detection and ICD therapy post-MRI.
Left ventricular sensing attenuation

Time frame: Up to 5 years post-approval

Proportion of subjects who experience left ventricular sensing amplitude attenuation >50% between pre-MRI and 30 days post-MRI.
