I just had an echocardiogram and the result was a backflow in the tricuspid valve. Is this similar to mitral valve prolapse. My Dr. said that it isn't a concern but I would love to hear from anyone with this same diagnosis. What are your symptoms, if any, etc. I have been having tachycardia at night, while I am sleeping, and am wondering if there is a conncection. Could this become more serious as you age? Thanks for all comments.
