Can left atrial enlargement be reversed?

In many cases, yes. Here are the scenarios in which left atrial enlargement can be reduced:

- If caused by high blood pressure, good blood pressure control can cause left atrial enlargement to regress in most cases.

- If caused by a leaky mitral valve, then mitral valve surgery may be curative, causing the left atrium to remodel to a more normal size.

- If caused by another condition, then addressing that specific condition may also reverse left atrial enlargement.
