What if you only had half a heart? Children born with HLHS will face this question their whole lives. Hypoplastic Left Heart Syndrome (HLHS) is a rare Congenital Heart Defect (CHD) that affects roughly 1% of children born with a CHD. In a child with HLHS, the left side of the heart is too small to pump blood out to the body, and, within a few days after birth, the child's body becomes oxygen-starved and medical intervention is required to keep the child alive. Surgical techniques were developed that have made living into adulthood a possibility but the question of what treatment will look like for adults needs to be answered. How long can a re-tooled heart do the work of a normal heart and what happens when it can't anymore?
