yocarditis is the leading cause of heart failure in individuals under 40 years of age (1). It frequently leads to dilated cardiomyopathy (2) and represents one of the most challenging diagnoses in clinical cardiology. Growing clinical evidence exists that myocarditis is a multifaceted disease, where different subtypes can be differentiated based on the predominant clinical presentation (3). Consequently, the diagnostic approach for myocarditis manifesting with symptoms of heart failure (heart failure-like myocarditis) should be different from myocarditis with acute infarctlike presentation (3-6). Establishing the timely and correct diagnosis, especially in individuals with heart failure-like myocarditis, is of importance because these individuals might benefit from a tailored therapeutic strategy. However, the primary tools for noninvasive diagnosis of myocarditis, including cardiac MRI and diagnostic requirements as defined by the Lake Louise criteria, have been shown to exhibit a very limited diagnostic accuracy in heart failurelike and chronic myocarditis (3-7). Recently, T1 and T2 mapping techniques have been introduced as quantitative approaches for a more reliable
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
