You are incorrect - the chest X rays in this patient demonstrate left atrial enlargement, biventricular enlargement and increased pulmonary arterial vascularity.
Your choice: LV Enlargement, Aortic Dilation - PA
These chest X ray shows left ventricular enlargement and aortic dilation.
Left ventricular enlargement, or dilation, is suggested by the increased cardiothoracic ratio, with the apex of the cardiac silhouette displaced downward into the left.
Aortic dilation is demonstrated by the widened superior mediastinal shadow bilaterally.
This chest X ray is consistent with chronic aortic regurgitation.
