Repair of aortico-left ventricular tunnel in the neonate: surgical, anatomic and echocardiographic considerations.

Repair of aortico--left ventricular tunnel was accomplished for the first time in the neonatal period. The diagnosis was made with two-dimensional echocardiography. Repair was accomplished using an open-patch aortoplasty technique, which prevented valvular insufficiency, a significant problem in older patients in whom the repair has been attempted.
