Swiss Cheese Myocardium: A Diagnostic and Prognostic Sign of HCM by Newer CMR Techniques

Abstract

Cardiac MR(CMR) has an important role in the evaluation of patients of suspected cardiomyopathies and also helps to differentiate between the various types based on the type of late gadolinium enhancements(LGE’s). We describe a characteristic Swiss cheese myocardium appearance in a patient with hypertrophic cardiomyopathy (HCM) using automatic scar analysis algorithm using low < 2SD scale threshold weighting to assess the replacement and interstitial fibrosis along with T1 mapping to quantify it.
