Baby's heart repaired in womb

Océane McKenzie had a severe narrowing of the left ventricle of the heart. If not fixed, the left side of the heart would not function. A team of doctors expanded her aortic valve using a balloon catheter inserted through the mother's abdomen 31 weeks into the pregnancy. Without the in utero procedure, Océane would have needed three surgeries after birth, and faced a shortened lifespan and long-term complications. The procedure allowed Océane to remain safely in utero for another month until she was born on April 15. CBC News
