A simple echo can reveal problems with the mitral valve. A cardiologist can often already detect problems with a heart valve by using only a stethoscope.
How much time has passed after placement of your stents? It can take some time for your heart to recover from the period of ischemia. Also, some anti-coagulation medication that you are taking now, can cause shortness of breath.
Slowly building up your ability to exercise during weeks/months after the placement of the stents can show remarkable improvements.
