Imaging signatures of high-risk arrhythmogenic genotypes in dilated cardiomyopathy.
Compared with TTNtv and genotype-negative DCM, HRAv is characterized by a distinct CMR tissue phenotype marked by more extensive myocardial injury and fibrosis, despite similar ventricular remodeling and systolic impairment, suggesting that CMR tissue characterization may help identify genotype-associated phenotypic di...
