Question:

I have mitral regurgitation and an enlarged left atrium.  What does this mean? 

I recently had an echo showing my left atrium (LA) was severely enlarged due to my LA volume index of 51 ml/m2. It also says that my left atrial size is mildly enlarged in another part of the report. I also have a moderate mitral valve regurgitation (MR). I had a mitral valve repair in 2001. My mitral valve at that time had severe regurgitation, secondary to an MI. I was 48. My MR has increased in severity since 4/2010, which was my last echo. My doctor didn't even mention the LA volume to me. Can you tell me what this means for my health status overall? It also says I have borderline pulmonary hypertension. I haven't been feeling very well since May and the doc thinks it may be because of my low BP. This has been an ongoing problem for me. He cut the Cardizem and I am feeling a little better, but not my best. I would appreciate any input you could give me.

Answer:

by Texas Heart Institute cardiologist, Roberto Lufschanowski, MD  

Roberto Lufschanowski, MDDear Alvera: The enlarged left atrium goes along with and is part of your disease (mitral insufficiency).  The rest of your questions require a formal consultation with your cardiologist.
