Hello.
I've just been recently diagnosed with moderate mitral regurgitation. At times I feel light headed and my chest feels tight or 'heavy' at times.
Just saw my cardiologist this month and I don't have to go back for another year for a echo. He also ordered a Cardiolite Stress test and it came back ok.
Hope this helped!
Keep smiling!
