Noninvasive imaging in cardiac deposition diseases

Abstract

Infiltrative cardiomyopathy represents a heterogeneous group of diseases of the heart tissue with similar phenotypic expression. The condition is rare, but can be easily mistaken for other more common conditions of the heart. The diagnosis of infiltrative cardiomyopathy is therefore challenging and has often required the use of invasive procedures in the past. In the last decade there have been great advances in non-invasive cardiac imaging modalities like echocardiography, cardiovascular magnetic resonance and nuclear imaging. Although no single imaging modality abnormality on its own is pathognomic for infiltrative cardiomyopathy, a combination of these different modalities are synergistic, and can greatly aid in the clinical diagnosis. In this review, we describe these advancements in non-invasive cardiac imaging modalities with a particular focus on cardiovascular magnetic resonance imaging. Level of Evidence: 1.
