Prognostic value of late gadolinium enhancement cardiac magnetic resonance in hypertrophic cardiomyopathy: a meta-analysis

Background Contrast-enhanced cardiovascular magnetic resonance (CMR) with late gadolinium enhancement (LGE) has emerged as an in vivo marker of myocardial fibrosis, although its significance in identifying high risk hypertrophic cardiomyopathy (HCM) patients remains unresolved. Previous meta-analyses have included studies with data involving overlapping patient populations, thus confounding effect estimates.
