I had mitral valve repair about 1-1/2 years ago. i began getting an ache in my chest about 3 weeks ago. i have shortness of breath. could this be?

Time to see a doctor: Chest pressure or pain with shortness of breath are signs that one should talk with her doctor right away or go to the E.R. In adults, chest pain can be a heart problem. She should not drive herself (safer by ambulance). If it turns out not to be a valve problem, myocarditis, heart attack symptoms, or anxiety attack symptoms, the E.R. will also have checked for problems such as a lung disorder.
