It has now been 6 weeks since my valve replacement op. Just wanted to update on the knocking sternum issue. Brought it up with my cardiologist. She said I was the first patient to report such an occurrence. She says it’s most likely an acoustic effect from the mechanical valve. Taking deep breaths also moves the heart and could make the sensation more pronounced. Younger patients (I’m 35) are also more sensitive to changes. Slowly beginning to get used to it!
I think I feel the same effect you’re talking about, six months out. I just figured it was normal for a mechanical valve.

Actually, I think I did bring it up with my cardiologist early on, and he said my heart sounded normal for one with a mechanical valve, including when I take deep breaths.
