Interrupted aortic arch with @entity1757 in the neonate is sometimes complicated by severe @entity475 from posterior deviation of the infundibular septum. We have developed a novel approach to the treatment of this condition. The infundibular septum is penetrated from the right-ventricular side to the left-ventricular outflow tract. It is compressed with patch fixation. The lower margin of the infundibular septum is everted. Three consecutive neonates were treated. The smallest diameters of the left-ventricular outflow tract were 3,4, and 2.5 mm. All @entity1 survived the operation and were discharged from the hospital. They remained well 2 to 7 years after the repair and were in normal sinus rhythm without a @entity714 or any significant pressure gradient between the upper and lower extremities. Follow-up two-dimensional and Doppler echocardiography demonstrated no residual shunt, no left-ventricular outflow-tract pressure gradient, and no @entity337 . This technique provides effective widening of the left-ventricular outflow tract, and is more safely and easily performed than conventional methods.
