I've posted previously, our daughter was born with a moderate VSD and small ASD at birth. She is now 4.5 months old. The ASD is now only a pinhole and her VSD has closed down to being 4 mm. It is restrictive (tissue from triscuspid valve), no signs of leakage, and her pressure differential is 68 mmHg. She has been in heart failure all summer (controlled by meds), however signs of heart failure are now gone. She was scheduled for OHS to repair, but given the size of the hole and the fact that her symptoms were improving, they cancelled surgery and will just follow her up.
Is there a chance that she will require surgery in the future, if the hole doesn't get any smaller? What are the risks of leaving it unclosed? Will she have any restrictions if it stays open and doesn't close completely?
