Valve replacement

Hello I was wondering if anyone could give me their experience/story of a recent valve replacement. I am 26F and have not had a valve replacement or open heart surgery since I was a young child. I am a bit concerned and do not know what to expect. I know this is a fairly simple procedure now a days but I still can't help but be nervous. Also has anyone had an issue with this procedure in replacing their pulmonary valve because their aortic valve was in the way (doctor said this may be an issue for me). Thank you!
