title: Ventricular septal defect creation for relief of tunnel subvalvular aortic stenosis.
abstract: In infants, the management of severe tunnel subvalvular aortic stenosis associated with hypoplastic aortic annulus remains a major surgical challenge. We report a case of such lesion treated by rerouting the systemic blood flow through a created subpulmonary ventricular septal defect toward the right ventricular outflow tract and the pulmonary valve. This technique provided complete relief of the left ventricular outflow tract obstruction without the implantation of a systemic prosthetic valve.
