Direct transaortic balloon valvuloplasty under cardiopulmonary bypass for neonatal critical aortic stenosis

A 1-day-old male infant with critical aortic valvular stenosis underwent balloon aortic valvuloplasty (BAV) under echocardiographic guidance during cardiopulmonary bypass. Left ventricular function dramatically improved after BAV. This technique combined with a surgical approach was safe and efficient.
