Transventricular balloon catheter aortic valvotomy in neonates.
Surgical intervention for critical aortic stenosis in neonates is associated with an appreciable risk. Refinements in the technique of aortic valvotomy have been developed in an attempt to lower the operative mortality. This case report summarizes our experience with transventricular balloon dilation of critical aortic stenosis in 2 neonates. Both patients survived operation with objective evidence of hemodynamic improvement.
