Ross-Konno procedure with interrupted aortic arch repair in a premature neonate.

A 1,700-g premature baby who presented with interrupted aortic arch type B, hypoplastic aortic annulus, severe subaortic stenosis, and large ventricular septal defect underwent successful surgical repair. A Ross-Konno operation was used to address the left ventricular outflow tract obstruction, hypoplastic aortic annulus, and ventricular septal defect. The interruption was repaired with a direct anastomosis.
