SummaryWe report a successful neonatal balloon aortic valvoplasty after prenatal diagnosis of critical aortic stenosis with severe left ventricular dysfunction. The infant was delivered by cesarean section at 34 weeks of gestation and had balloon valvoplasty via the right common carotid artery 67 minutes after birth. Left ventricular contraction improved immediately after the procedure. Scheduled balloon aortic valvoplasty immediately after birth subsequent to prenatal diagnosis can improve the outcome of critical aortic stenosis.
