Atrial fibrillation treated during mitral valve surgery

Atrial fibrillation is an irregular heartbeat that originates in the upper chambers of the heart. The mitral valve is one of the valves in the heart, located in the left upper chamber of the heart. Often, patients who are initially diagnosed with mitral valve disease are also found to have atrial fibrillation.  Atrial fibrillation and mitral valve disease frequently occur together, and may require surgery.

There is agreement among several international medical societies that encourages those hospitals with experience treating mitral valve disease and atrial fibrillation to treat both diseases during a single surgery. 

About this measure

This measure displays the percentage of patients who in 2011 received surgical treatment for atrial fibrillation and mitral valve disease during the same surgery.

Note: In this case, a higher number is better.
