Here's an update for you on Simi's appointment with his pediatric cardiologist: We've been going annually to monitor his atrial septal defect, or hole between the two atrial chambers of his heart.
Summary:
In a nutshell, we're going to wait until this time next year before closing the defect. On May 12, 2006, we'll do another echo of the defect and talk with his Dr. about the best method of closing it. At that time, I think we'll go ahead and schedule "it" (whatever method "it" may be).
Background:
When he was under two, the Dr. said the only way to close the defect was open heart surgery, where they open his chest, break open his rib cage, stop his heart, and put him on a heart/lung bypass machine for hours, then sew a patch where the hole is. The risk of complications is 1% (amazing it's not higher), but it's highly invasive and requires a long recuperation period. Plus, being on heart/lung bypass reduces your mental capacity.
Last year, the Dr. said that he now qualified for a (much) less invasive procedure, where they can snake a catheter in through a vein in his leg and place a device (amplatzer) in the hole to close it. The reason he suddenly qualified is because there is now tissue on either side of the hole, which they need to anchor the device. Last year, the Dr. said that kids do better the bigger they are and suggested we wait a year. So we did.
More information on this visit:
This year, after doing the echo, the Dr. said that there is a 70-75% chance that they'll be able to do the amplatzer catheter procedure, but they'll only know that when they go in to place the device. (Last year, we didn't realize that there was a chance they couldn't do it.)
It's questionable just how much tissue he has on either side of the hole and they'll get a better view of it when they go into his heart. One side, in particular, has less tissue than the other side. So we could submit him for the catheterization procedure - go through the four hour procedure and its risks - only to have to submit him again for open heart surgery.
Timing (age of the child) has its factors too. The younger the child, the less they remember and the less emotionally traumatic it is. It's important to close it before the child starts school so he doesn't miss 6+ weeks of school.
While our memories can certainly fail us, both Raj and I thought there was more tissue on either side of the hole this year over last year. And the year before, there was no tissue at all on one side. So it seems like the tissue is growing. At worst, we'll still have the same odds next year that we do this year.
So we decided to wait a year - with the hope that the tissue on either side of the hole will grow and we'll have improved odds for a successful amplatzer device. Simi will be 4 1/2 then with the plan to close it before he's five.
