Doctors from SickKids and Mount Sinai Hospital, inserted a balloon into Sebastian’s heart, via a needle placed under ultrasound guidance through his mother’s uterus, to open up the atrial septum. It is believed that this is the first time in the world that this procedure – a Balloon Atrial Septoplasty (BAS) – has been performed before birth to treat Sebastian’s particular condition.
