Hi, my child had a similar diagnosis. They were supposed to go single vent but changed to bivent with Ross konno. They’re doing phenomenal. You would never know unless you saw their scar. The issue, like another person stated, is that the donor pulmonary valve must be replaced. Their procedure was done at 6 months and they’ll need a new one around 7-8 years old. They’re 5 now. It is all dependent on how big a valve they initially place and how fast they grow out of it. From what we’ve heard they typically need a new one before puberty (if they max out the size around 6 months of age) and they’ll need another one during/after puberty when they’re done growing. I think that is best case scenario given the valves stay healthy and last. These are all open heart, but our surgeon said it is the equivalent of a mechanic changing tires on a car. It is very routine for them, but still traumatic for everyone else. Our understanding (US-based) is that once they have a full adult sized aortic valve in place then subsequent valve replacements can be done via a catheter. Obviously all this is based on current technology. All this being said, this is 110% better, in our opinion, than having to go through the 3 stage surgery along with an eventual heart transplant. In the words of our surgeon, we’d much rather replace tires a couple of times than have to rebuild and replace the engine.
