CXR shows a triangular shaped heart with upturned apex indicating right ventricular enlargement . In addition there is left atrial enlargement characeterised by elevated left mainstem bronchus, double density and straightening of the left heart border. These findings are consistent with mitral stenosis
and likely rheumatic in origin

CXR shows a very prominent soft tissue structure in the AP window. In this case the diagnosis is corrected transposition. Differential diagnosis includes partial absence of the pericardium
