Roseville Baby Battles Rare Heart Defect at UCSF Children’s Hospital

Allison and Jon Smith first learned from an ultrasound that the baby boy they were expecting would be born with a severe and rare heart defect. In Hypoplastic Left Heart Syndrome, or HLHS, the heart does not develop properly and the infant is born with only one ventricle contributing to circulation, essentially having only half a heart. The Smiths were referred to UCSF Pediatric Heart Center at UCSF Children's Hospital.
