What surgery has this patient had?
This patient has had a sternotomy and a prosthetic mitral valve.
Are any of the cardiac chambers enlarged? If so which ones?
There appears to be a degree of global cardiomegaly, however the left atrium is by far the most strikingly enlarged.
What features of left atrial enlargement can you see?
A double contour is seen through the right side of the heart. The size of the left atrium measured from the mid point of the left main bronchus (which is elevated) to the mid point of the double density line is clearly more than 7cm. The subcarinal angle is also enlarged, much more than the upper limit of normal taken to be 90-100 degrees.
This patient has had a sternotomy and a prosthetic mitral valve. There is splaying of the carina with elevation of the left main bronchus, a double right heart border and cardiomegaly. The features are those of left atrial enlargement.
Pulmonary vasculature is prominent particularly in the upper zones.
