Papillary muscle infarction (PMI) is a serious consequence of acute myocardial infarction (AMI). The objective of this study was to prospectively compare free-breathing navigator 3D with breath-held 2D delayed enhancement cardiac MR for PMI detection in a cohort of patients presenting with AMI. 25% (n=27) had PMI as determined by either 2D or 3D imaging. Navigator 3D imaging was found to provide improved detection of PMI compared to breath-held 2D imaging.
