Tetralogy of Fallot with aortic stenosis: repair without aortic valve intervention.

A 14-day-old boy with tetralogy of Fallot (ToF), ductus-dependent pulmonary circulation, and significant aortic valve stenosis (AVS) underwent primary repair of ToF without aortic valve intervention. The pressure gradient through the aortic valve decreased spontaneously after the operation. This may have been due to the reduction of blood flow through the aortic valve postoperatively. For patients with ToF, AVS, and ductus-dependent circulation, ToF repair alone may alleviate the severity of the AVS.
