Preliminary evidence suggests that multi-detector CT (MDCT) angiography also can detect irreversible myocardial scarring through the detection of regions of delayed hyperenhancement (DE) of the myocardium.1-4 However, existing studies have been performed in single centers, and the reproducibility, and impact of this modality on recovery of myocardial function is unknown. In this study, the investigators propose a single-center trial using a standardized MDCT DE protocol among patients scheduled for clinical cardiac CT with planned reoperative surgical. The primary endpoint will be characteristics of DE imaging of the myocardium including its inter-reader variability and factors associated with image quality. These findings will further our understanding of the role of DE MDCT for the detection of myocardial viability.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Eligible patients will be adults, ages 18 and above with:\n\n 1.
