Interesting post. I had surgery on my aortic valve and ascending aorta seven years ago. I’m told that in addition to the techniques you list, the doctors also used reverse perfusion (pumped oxygenated blood in the reverse direction to maintain oxygen supply to the brain). I’ve had no symptoms of “pump head”.
Yep, aortic valve & ascending aorta are definately two surgeries that require circ arrest. I’m glad you haven’t had any pump head!
The first circ arrest case I did as a grad student was on a 6 year old boy with a congenital cardiac defect. The surgeon was having lots of difficulty, and we had to arrest him for 68 minutes!!! Thankfully, he did quite well afterward. No neuro deficits.
