I'm not on dialysis so I'll pass on the question "does dialysis have an impact on heart valves". I''ve never heard about that. Does OHS have an effect on your 1 kidney. Yes it does.
My first AVR surgery I wasn't even aware I only had 1 kidney. I only found out months before my second because my primary wondered why my creatinine level was a bit high. He wanted a kidney ultrasound to find out if I had a kidney stone. During the ultrasound, seems like the tech had a hard time finding the second kidney. LOL. A cat scan determined I didn't have one!
As I was ramping up for my second AVR, all the doctors did what they could to try and minimize any impact a procedure would do. I took something prior to both my cath and cat scan with contrast to minimize the effect the dye had on my single kidney. I also had extra IV hydration prior as well. Dr. Miller thought it a possibility that I would need dialysis after my surgery either short or long term. Fortunately with all the other compilications I had, dialysis wasn't one of them.
I believe user retiredmls went through surgery recently having only 1 kidney. Just make sure your surgeon and cardiologist are aware of your 1 kidney situation. It will change the way they approach your procedure(s).
