My heart is malformed but it works just fine. All of the pressures are good. I'm just a little sore, no big deal there. The hard part was laying on my back for 4 hours. I cried like a little girl, nery painful with the back injury I got from falling down the stairs. Oh yeah, I fell down the stairs. No real injuries to bones, just soft tissue. I am in good spirits today and I love everyone. No wonder painkillers are so addictive.
