ProMRI: ICD safe in patients undergoing cardiac, thoracic spine MRI

ProMRI: ICD safe in patients undergoing cardiac, thoracic spine MRI
May 21, 2015

Read the Perspective from Andrea M. Russo, MD, FACC, FHRS

BOSTON — An implantable cardioverter defibrillator was safe and effective in patients undergoing a cardiac or thoracic spine MRI at 1.5 T, according to the results of the ProMRI study.

Researchers conducted a multicenter prospective, single-arm, nonrandomized study to evaluate the clinical safety of the ICD system (Iforia ProMRI, Biotronik). Khaled Awad, MD, from the University of Alabama at Birmingham, and colleagues enrolled 170 patients implanted with a dual-chamber (DR-T) or single-chamber (VR-T DX) ICD system. Nondiagnostic cardiac MRI or thoracic spine MRI was performed at least 1 week after enrollment, with the ICDs placed into MRI mode, with ventricular fibrillation detection and therapy programmed off.
