These chest X rays show left ventricular enlargement and a dilated aorta.

The PA view demonstrates cardiomegaly, as evidenced by a cardiothoracic ratio greater than fifty percent.

The ascending, transverse and descending aortic shadows are also prominent.

The lateral view shows left ventricular enlargement , as evidenced by posterior displacement of the left ventricular shadow.
