From: Clinical genetic testing in four highly suspected pediatric restrictive cardiomyopathy cases
Representative images of cardiac X-ray, MRI, CTA, and two-dimensional echocardiography. LA left atrium, RA right atrium. a (case 1), b (case 2), c (case 4): Chest X-ray showed increased heart shadow without calcification of the pericardium, thickened pericardium, or endocardium. d (case 2), e (case 4): Cardiac MRI showed bi-atrial enlargement without calcification of the pericardium, thickened pericardium, or endocardium. f (case 4): Cardiac CTA showed bi-atrial enlargement without calcification of the pericardium, thickened pericardium, or endocardium. g (case 1), h (case 2), i (case4): Two-dimensional echocardiography showed dilation of the left and right atria with normal ventricular sizes, without calcification of the pericardium, thickened pericardium, or endocardium
