Dad pulled through another night and my mom is hopeful that he'll be released by this weekend.
The doctors can't do the valve replacement surgery. All they can do is make him comfortable.
Thank you for all your prayers and well wishes for my dad.
*** To my kin that might read this blog post****
Please don't go ape by finding out this way and please respect my dad's wishes to not be calling him while he is in the hospital or trying to reach Mom because both need rest. Even I don't call the hospital for information. I know that he needs his rest and that calling to find out information is only going to take nursing staff away from helping others to make me feel better. VA hospitals are short staffed.
I will post updates here as I find out more.
