Hi,
Our son was diagnosed with aortic stenosis with a bi-cupsid valve (similar to Bagpuss) plus a hole in the heart with regurgitation (basically the blood seeps through into the wrong chambers of the heart because the valve slips) when he was 13 days old. We only found out when he began throwing up and the wonderful GP felt his oxygen levels were too low so rushed us to our local hospital. They stablised him overnight. He had to have a feeding tube put down his nose as his heart was so weak it was struggling to get his digestive system working. The next day he was rushed to the Evelina Children's Hospital where he had a balloon catheterisation. His stenosis was severe. We were told it was the procedure or he would die within a month as his heart couldn't run the digestive and respiratory system at the same time so his body had decided to breath rather than feed - basically he was starving himself in order to try to live. We had been struggling to get milk down him - he'd take ages to complete a bottle (I'd had problems breast feeding which was lucky in a way as we could see how little/much he was actually taking at each feed) So the procedure it was.
He had the procedure at 15 days old. Two days later we transferred back to the local hospital and the next day we came home. He went from taking an hour to feed to finishing a bottle in 20 minutes! Our milk monster (as he then became known) was born!
He started having check ups every three months, then that reduced to every six months. He's now five years old and, for the past three years, has annual check ups as his valve is holding up (they were expecting it to fail before his second birthday). He's at school full time, does PE and drama and can outlast his friends at parties (I have known his friends to be asleep on the sofa at playdates when he was younger and our son still going strong).
I celebrated a BIG birthday a few months ago. We went to bed at 2am - our son was still on the dancefloor with his older cousins at 1.30am. He woke up at 8.30am and did a full day playing at home!
We know our son will have to have a similar procedure at some point and may have to have open heart surgery but we also know heart surgery is leaping forward so we hope the surgery becomes easier before our son needs it.
The surgeon we were lucky enough to have treating our son said to me, on the day we transferred back to the local hospital, "Our job is to treat your child as a patient, your job is to treat him as a child. Let him enjoy his childhood - he has to climb trees, scrape his knees and be a boy. The first time he goes out alone you'll panic, the day he leaves home you'll be having kittens. But it is his life and he has to lead it the best way he can. Your job is to make it a good life the best way you can." I've never forgotten that so our son does everything his friends do. He knows he has a heart condition, he knows what to do if he feels unwell and his friends parents all know too (as does the school). If he feels breathless he stops what he's doing and rests for a few minutes (well, 30 seconds in his case, he hates to miss a thing!) He's had one day off sick from school in the past year. Some of his friends seem to pick up every bug going in comparison.
I also tell people I feel lucky. Our son has a diagnosis. He and we know what he has and what to do to keep him safe. There are a lot of parents out there who have lost children to undiagnosed heart conditions - what you don't know about CAN hurt you in this case.
So, I really know how hard it is, but try not to step too far ahead into the realms of what might happen. Children are amazing creatures. Our son doesn't realise that he's not suppose to have this energy! I used to lay awake every night worrying about our son's future. Then I realised that, whatever that future is, IT IS HIS and he will make the best of it with our help and encouragement just like every other child. We owe it to him to help him get as much enjoyment and achievement from the life he'll have as possible - so my energy goes into helping him do that rather than worrying now.
Sorry, I've waffled on so I hope you'll be able to pick your way through this and make some sense of it. Good luck!
