Hi Jennifer,
I can understand if you're feeling a bit anxious about this. When it comes to the heart, there isn't anything that makes you feel good about it, right!
I have a Lupus heart condition called Libman Sachs Endocarditis. It's inflammation of the mitral valve (4th valve). The inflammation causes the valve to thicken and not work properly. The valve allows blood to flow back and forth instead of just forth. The condition is also called mitral valve prolapse.
It's treated with prednisone. Once the inflammation is taken care of, the prolapse is gone. Some people will develop a heart murmer with this too. I had that also. The condition was one of the symptoms that brought me my diagnosis. The treatment helped immediately and I haven't had much issue with it since. I get an echo every year and for the past 5 or 6 years now, I have little to no prolapse, and the heart murmer is gone.
Symptoms of this are intense heart palpitations. No pain.
Good luck with your echo, and let us know what you learn okay!
Ginny
