Abstract

Non-ischemic cardiomyopathies include a wide spectrum of disease states afflicting the heart, whether a primary process or secondary to a systemic condition. Cardiac magnetic resonance imaging (CMR) has established itself as an important imaging modality in the evaluation of non-ischemic cardiomyopathies. CMR is useful in the diagnosis of cardiomyopathy, quantification of ventricular function, establishing etiology, determining prognosis and risk stratification. Technical advances and extensive research over the last decade have resulted in the accumulation of a tremendous amount of data with regards to the utility of CMR in these cardiomyopathies. In this article, we review CMR findings of various non-ischemic cardiomyopathies and focus on current literature investigating the clinical impact of CMR on risk stratification, treatment, and prognosis.

Keywords: Cardiomyopathy; Magnetic resonance imaging; Heart; Cardiovascular imaging; Cardiology

Core tip: Cardiac magnetic resonance imaging (CMR) has established itself as a vital modality in the evaluation of numerous aspects of non-ischemic cardiomyopathies, ranging from establishing a diagnosis to detailed analysis of cardiac function. Lately, increasing data has become available regarding the clinical utility of CMR in the evaluation of these patients, although few articles have consolidated this these findings regarding CMR’s impact in these pathologies. This review will summarize current literature investigating the clinical impact of CMR on risk stratification, treatment, and prognosis in the setting of non-ischemic cardiomyopathies.
