I created this post quite some time ago, but life has gotten a bit hectic again lately so I haven't been able to do much of anything. Just a quick update, my father flew out to Houston again on Monday, had another procedure (the same one he had last time, just patching up some smaller leaks this time) and everything went well.
My parents are probably sitting in the airport in Houston now getting ready to come home. Pretty amazing that they can preform a surgery on your heart and a day later you are discharged from the hospital.
Hopefully this will correct the issues that my father has been having. There is a good chance that he will have another procedure to help more issues that his heart is having, but this one should correct the serious problems.
Here's hoping the problem stays solved this time....
