Does anyone have any experience of this surgery? Murmur was picked up at 6 week check and hole confirmed at st Thomas's a couple of days ago. Surgery expected to be in a few weeks. She's always been small (5lbs 4oz at full term) and is only 9lbs now, probably due to the VSD so I know it needs fixed but it is still a scary thing for one so small. She's a smiley happy baby but I'm now getting paranoid about everything from breathing heavily to not feeding enough or looking pale. Open heart surgery just sounds so drastic but I'm assured this is as routine as such things get.
