I have just gone through the test for aortic valve calcification. I have had two Echos done and just did the Echo stress test. I could not do the Echo stress test. The minute they started the tread mill I was done. I exercise a lot but DO NOT TOLERATE A TREAD MILL WELL. I am being told I need to have the bicuspid Aortic valve replacement. I am in the process of looking into surgeons and hospitals.
