These chest X rays show left ventricular enlargement and left atrial enlargement.  
	
This PA view demonstrates the enlarged  
left ventricle as an increase in the inferolateral cardiac border associated with an increased  
 cardiothoracic ratio .  The markedly enlarged  
left atrium is manifested by the double contour within the heart border, an elevated left  
mainstem bronchus, and an enlarged  
left atrial appendage.   
The lateral view with barium swallow, demonstrates posterior displacement of the 
esophagus by the markedly enlarged left atrium.
