January 14, 2022 – During a routine ultrasound early in her pregnancy, Rebecca Jones and her husband Brent were devastated to learn there was something wrong with their baby’s heart. The expectant parents learned their baby, Gabrien, had a rare heart defect called transposition of the great arteries, a condition in which the two main arteries leaving the heart are reversed. Their obstetrician referred them to Dr. David Drossner, a pediatric cardiologist and director of outpatient cardiology at Nicklaus Children’s Hospital.
