valve disease

Hi.I am a 41 y/o active female and this past year I have had difficulty getting my exercise program going. I try to swim or run(easily) and this seems to go ok but afterwards I am so tired I can't do anything else for the rest of the day or days after. Bedrest helps. For the past six months I have experienced flutter sensations usually when lying down and mild SOB when I am trying to read aloud to my daughter. For the past month I have experienced what feels like a change in pressure in my chest, or loss of breath. I cough and this seems to help but now I am coughing throughout the day. I also have had some on/off banging sensations in my chest that feel very mechanical. I did have an echo which indicated mild regurgitation of aortic valve, tricuspid valve, mitral valve and mitral valve prolapse. Possible mild Pulmonary hypertension .EF was 70 and no dilation of LV. Now I seem to have mild central chest pain especially when  stressed or  tired.I am going to see a cardiologist in three weeks( earliest appointment I could get). My 11 y/o daughter was born with single ventricle, dextrocardia and pulmonary atresia. She has a completed fontan.
My questions are: does pulmonary hypertension precede valve regurgitation, are they related?
Isn't valve regurgitation fairly common ,could this cause fatigue?
I am wondering about a possible mild heart or valve defect given my daughters history  .. is that possible?
Thanks for your consideration.

Dear michisan,
Although severe valvular disease may lead to problems mild valvular regurgitation does not cause pulmonary hypertension or fatigue.  If you had a normal echo heart defects would be unlikely.

Hello
Your symptoms may be indicative of asthma.  I developed asthma at age 30.  It can present in different ways, and coughing is one way.  When I got it, I developed a cough, mostly at night or after exercise.  I didn't know I was wheezing until I went to the doctor.  
Get it checked out.  Good luck!
