After Kimble got all set up, with all his art lines, IVs, and other stuff, Dr. Campbell opened him up and took a look at his tricuspid valve, which is the valve that sends blood from his right atrium (top holding chamber of right heart) to his right ventricle (bottom pumping chamber of right heart). It's been small and troublesome this whole time. Anyway, the hope was that this valve possibly just needed some tweaking, and then there would be more bloodflow. More bloodflow means happy results.
The tricuspid does not have any threads, or fibers, that are attaching it to the right ventricle, which allows for it to contract and release, as blood goes through there. So, there is nothing to "tweak". Simply stated, it's a bum valve. It won't get better.
So, Dr. Campbell is doing The Glenn, which will re-route half his bloodflow (from the top part of his body)directly to the lungs, instead of going to his heart, and going through that tricuspid valve. The bloodflow from the bottom part of his body will still go through his heart. We are hoping that his right heart will be able to handle that amount of bloodflow. Our doctors seem to have high hopes that it will.
That is the latest news right now. We'll see what the remaining time in surgery will do. This remaing time, will probably be another three hours or so.
