AIM: Myocardial fibrosis is fundamental in the pathogenesis of heart failure. Late gadolinium enhancement (LGE) with cardiac magnetic resonance (CMR) imaging is commonly assumed to represent myocardial fibrosis; however, comparative human histological data are limited, especially in non-ischaemic cardiac disease. Diffuse interstitial myocardial fibrosis is increasingly recognized as central in the pathogenesis of cardiomyopathy and can be quantified using newer CMR techniques such as T1 mapping. We evaluated the relationship of CMR assessment of regional and diffuse fibrosis with human histology. METHODS AND RESULTS: Eleven patients on the waiting list for heart transplantation (43.5 ± 7.6 y..View full abstract
