Myocardial Scar and Mortality in Chronic Aortic Regurgitation [PDF]

Journal of the American Heart Association, 2020
Background Chronic aortic regurgitation (AR) can be associated with myocardial scarring. It is unknown if scarring in AR is linked to poor outcomes and whether aortic valve replacement impacts this association.

Real-World Comparison of Cardiac MRI and Nuclear Perfusion Imaging for Myocardial Scar Detection [PDF]

JACC: Advances
Background: Cardiovascular magnetic resonance late gadolinium enhancement (CMR-LGE) is the reference standard for scar detection, but data comparing LGE with fixed perfusion defects (FPD) on nuclear myocardial perfusion imaging (MPI) are limited.

ScarElastic: continuous elasticity field modeling for myocardial scar delineation in LGE-CMR [PDF]

npj Digital Medicine
Late gadolinium-enhanced cardiac magnetic resonance (LGE-CMR) imaging is a crucial modality for identifying myocardial scar, yet current binary segmentation approaches often fail to capture the continuous and heterogeneous nature of fibrosis.

Cardiac magnetic resonance -detected myocardial injury is not associated with long-term symptoms in patients hospitalized due to COVID-19.

PLoS ONE, 2023
BackgroundLong-term symptoms are frequent after coronavirus disease 2019 (COVID-19). We studied the prevalence of post-acute myocardial scar on cardiac magnetic resonance imaging (CMR) in patients hospitalized due to COVID-19 and its association with ...

Time-efficient three-dimensional transmural scar assessment provides relevant substrate characterization for ventricular tachycardia features and long-term recurrences in ischemic cardiomyopathy

Scientific Reports, 2021
Delayed gadolinium-enhanced cardiac magnetic resonance (LGE-CMR) imaging requires novel and time-efficient approaches to characterize the myocardial substrate associated with ventricular arrhythmia in patients with ischemic cardiomyopathy.
