Incremental prognostic value of late gadolinium enhancement in hypertrophic cardiomyopathy in a large contemporary cohort.

Diffuse Fibrosis in Hypertrophic Cardiomyopathy: Incremental Prognostic Value of Extracellular Volume.

BACKGROUND Left ventricular (LV) myocardial extracellular volume (ECV), from cardiac magnetic resonance (CMR) T1 mapping, primarily reflects diffuse fibrosis and is a marker of adverse myocardial remodeling in hypertrophic cardiomyopathy (HCM). OBJECTIVES The authors sought to evaluate the prognostic value of ECV bey...
