Chest radiograph in a 6-year-old patient with a large secundum atrial septal defect
The chest radiograph demonstrates moderate cardiomegaly with increased convexity of the right side of the heart (arrowheads). There is a large pulmonary outflow tract (arrow) and increased pulmonary vascularity. These findings are consistent with the presence of a large left-to-right shunt.
