Hi, everyone, Tomorrow my AVR will be 4 weeks past and things continue to go well. I feel stronger now when I walk and on most days I no longer take a nap. My question for you, however, Is it possible to feel a bioprosthetic valve? For several days now when I do something that causes my heart to beat more strongly for a few minutes I feel each beat as a thump in the upper part of my chest. Have any of you experienced such a sensation? I've been wondering if the stent, the hard part of the valve that supports the leaflets, can be causing the very pronounced bump or thump. There is no other sensation like there was with palpitations that left me feeling ill; it is just a thump.
