Hemodynamic Response and Safety of Vasodilator Stress Cardiovascular Magnetic Resonance in Patients with Permanent Pacemakers or Implantable Cardioverter ‐Defibrillators

ConclusionThis data supports the safety of vasodilator stress CMR with promising diagnostic quality images in patients with CMR conditional ICDs and PPMs. Despite a near uniform tachycardic response to regadenoson in the SPECT environment, high rates of asynchronous pacing during vasodilator stress CMR did not result in competitive pacing or adverse arrhythmic events. Further studies are needed to validate these findings and confirm the diagnostic and prognostic performance of stress CMR in these individuals.This article is protected by copyright.
