a In an apical 4-chamber view, biventricular wall thickening, granular sparkling (arrowhead), thickening of the mitral and tricuspid valves, and a trivial amount of pericardial effusion next to the right atrium are visible in the systolic phase (arrow) (patient 6, age 65). b In a parasternal long-axis view, a left atrium dilatation and a very thick granular myocardium (arrowhead) with some pericardial effusion (arrow) at the baso-posterior wall are evident (patient 6, age 65)
