As many of you know, Sammy's been having a bit of trouble with his oxygen saturations lately. Oxygen saturation, commonly abbreviated as "sats", measures the percentage of hemoglobin binding sites in the bloodstream occupied by oxygen. (from wikipedia) Heart-healthy people are typically at 99-100. Sammy, right after the Fontan, was in the low 70s. The lower the sats, the bluer a person will look and the amount of oxygen circulating throughout the body (and to the organs) will be lower.
During the Fontan, they created a fenestration (a hole) to help his body handle the change in pressures with his new circulation. His fenestration was "generous" and we knew that his sats would remain on the low side until they closed the fenestration by cath in a year or two. His cardiologist was fine with this, and we all expected his sats to increase over the months following the Fontan. And they did - Sammy was up in the 80s for a while this summer. We knew, too, that the more active he was, the more mixing of blood across the fenestration there would be, and the bluer he would turn until he calmed down and rested. Again, no one seemed concerned about that, so even though I think it unsettled us both a bit, we trust his cardiologist very much.
Over the past few weeks, Sammy has had a couple of episodes where he turned very blue. (Think blue-raspberry lollipop mouth and purple fingers.) We put him on the sat monitor, only to find out that he had dropped into the 50s. Since he remained (incredibly) active through it, his cardiologist didn't think it was an immediate need to have him seen. What is more concerning to them, however, is not those blue "episodes" so much as it is that his overall sat levels have decreased over the past few months. Where he was in the 80s over the summer, he is now back into the low to mid 70s - not ideal. And that they decreased instead of increased (and settled out) means a fun ol' trip into Boston for us. Since there shouldn't be much fluctuation post-Fontan, and since he's remained very active, they don't believe it's anything cardiac. The job now is to figure out what, if anything, it is.
Today, Sammy is scheduled for an EKG, xray and echo. Please keep him in your thoughts. We're hoping that it's just Sammy and these shifts in saturations will be fixed once he has a cath to close the fenestration. But please pray that if there is a problem, it is easily detected and easily remedied. Thanks so much.

Interestingly enough, Aidan (our 5-year-old with HRHS) just had a cardiology appointment where we discussed the fenestration. However, his sats are in the high 80's and he is 2 years post-fontan.
My question is why wait to close the fenestration? Is it too soon past the surgery? I know that HLHS kids can be treated differently than HRHS ones.
Prayers are being sent your way.
