Abstract
Summary
Cardiomyopathies were originally defined as primary myocardial disorders of unknown cause; while heart muscle disorders of known aetiology or associated with systemic disorders were classified as secondary or specific heart muscle diseases.
World Health Organization classification of cardiomyopathies are dilated cardiomyopathy, hypertrophic cardiomyopathy, restrictive cardiomyopathy, arrhythmogenic right-ventricular cardiomyopathy, unclassified and Specific cardiomyopathies as Ischemic, valvular, hypertensive, myocarditis, amyloidosis, Fabry disease,…
T1 mapping and Feature tracking cardiac magnetic resonance have good capability in assessment of myocardial scarring and contractility disorders in cases of cardiomyopathy (different types) and enable quantitative analysis of myocardial deformation without lengthening the imaging protocol or the CMR examination which agree with previous studies as being an important indicator of myocardial disorder.
Myocardial T1 mapping is proving to be a robust indicator of early myocardial disease in many conditions, and normal ranges and guidelines for postprocessing have been published by the Society of Cardiovascular Magnetic Resonance.
CMR FT-based Strain analysis is able to differentiate underlying myocardial mechanics between different types of cardiomyopathy.The ability to discriminate these conditions may aid in deeper understanding of pathophysiology in future.
