Diagrammatic representation of the gross phenotype of normal heart and primary inherited cardiomyopathies at short axis cut. Normal heart, hypertrophic cardiomyopathy (HCM), dilated cardiomyopathy (DCM), arrhythmogenic cardiomyopathy (ACM), and restrictive cardiomyopathy (RCM). Note that in primary RCM, at cross section, the phenotype is usually not distinct from normal heart, and atrial dilatation in the absence valvular and endocardial diseases is the red flag at gross examination
