Patients with end-stage heart failure (HF) often require advanced therapeutics, but current clinical profiles and biomarkers are not adequate for predicting outcomes. Myocardial perfusion reserve may be an important predictor, but it is technically challenging to perform perfusion MRI in patients with end-stage HF because they often have implantable cardioverter defibrillator (ICD), which generates significant image artifacts. We developed a novel cardiac perfusion pulse sequence using a wideband saturation pulse. Compared with standard perfusion MRI, wideband perfusion MRI suppresses image artifacts induced by ICD.
