Thank you so much for your explanation. I also have the bicuspid valve and the aneurysm to go along with it. Mine is at a 4.6 and I am screened yearly. Last August it was stable from the year before, so I was happy about that. So far the valve is working fine. My son, who is 38 has the same thing. His is at a 4.2.Neither of us dwell on this or even think about it that often. We just try to live life to the fullest and what will be will be. It is comforting to know that others are in our same situation. Best of everything to all of you dealing with this.
