Percutaneous Fetal Atrial Balloon Septoplasty for Simple Transposition of the Great Arteries With an Intact Atrial Septum

摘要

We report the first ultrasonographically guided percutaneous balloon atrial septoplasty (BAS), to our knowledge, in a fetus with transposition of the great arteries and an intact ventricular and atrial septum (37 + 2 weeks). After vaginal delivery at 38 weeks, the infant had an elective septostomy (day 1) and an arterial switch procedure (day 7), with an uneventful postoperative course. For centres with experience in fetal cardiac interventions, fetal BAS is a superior management option compared with the alternatives for this high-risk physiology.
