Receiver Operating Characteristic (ROC) curves of three methods for assessing the size of the proximal ascending aorta (PAA) on echocardiography; BSE recommended methods using height and sex (Method 1, green), body surface area, age and sex (Method 2, red) and height2.7, age and sex (Method 3, blue). Sensitivity and 1-specificty values for each method at the PAA diameter of 4 cm is plotted. Of the 6902 studies, 306 PAAs were > 4 cm. Method 1 classified all PAAs > 4 cm and 1885 < 4 cm as dilated; Method 2 classified 111 PAAs > 4 cm and 82 < 4 cm as dilated; and Method 3 classified 203 PAAs > 4 cm and 476 < 4 cm as dilated
