Sammy has a heart cath to close his fenestration next Friday, September 25th. He will go in on Thursday for pre-op - bloodwork, EKG, xray, etc, and then they'll let us know when to bring him in Friday. They plan on keeping him overnight Friday night for observation, and if all goes right, he should be discharged Saturday morning.
When Sammy had his lateral tunnel Fontan last May, the surgeon created a hole, or "fenestration". This was to help his system adjust to the new circulation and pressures created by the Fontan and is a very routine choice for Children's Hospital Boston. In some children, the fenestration will close on its own, but in most it needs to be closed with medical intervention.
Currently, the fenestration allows for considerable mixing of his oxygenated and non-oxygenated (red & blue) blood. His oxygen saturations (sats) hover in the 60s and have for quite some time. As it hasn't slowed him down much, it wasn't a great rush to close the fenestration. But as he grows, he does seem to get out of breath quicker and man, the kid can turn blue! (Purple fingers and toes, lips that look like he's been eating a blue raspberry lollipop and just a general bluish tone to his skin.) So the hope is that by closing the fenestration, the blood can't mix anymore and his sats will go up into the high 80s and (we would LOVE to see) the 90s. This means that more oxygen will be getting to his organs and the rest of his body - most kids after this point are PINK. We've only ever seen a fairly pink Sammy while he was on oxygen in the hospital. He should have more energy after this as well. (More??!?! I asked his cardiologist if this procedure also gives mom and dad more energy as well - we can hardly keep up with him right now!)
There's a diagram of a fenestrated fontan here; Sammy's anatomy isn't exactly the standard HLHS, but it gives the general picture.
Please keep the usual suspects in your thoughts and prayers next week - Sammy, the doctors, nurses, Daddy, Mama. Thanks!
