The purpose of this research is to investigate the best way to manage evolving hypoplastic left heart syndrome (HLHS).
The condition occurs when part of the heart doesn't develop properly so the heart is not able to pump blood around the body effectively. Babies born with this condition require surgery and are often left with a lifelong heart disability. A number of babies with this condition will die during pregnancy or within the first year of life (approximately 10-40%). We are investigating a treatment given during pregnancy in which a balloon is used to increase the size of the baby's aortic valve. The aortic valve function is to allow easy flow from the heart to the body and prevent blood from returning…
