Truncus arteriosus: successful surgical correction without the use of a valved conduit

A new operation for the restoration of continuity between the right ventricle and pulmonary circulation in truncus arteriosus in infancy without the use of a tube graft is described. This was achieved by anastomosing the inferior margin of the detached confluent branch pulmonary arteries to the apex of a vertical infundibular ventriculotomy to form the posterior wall of the reconstructed right ventricular outflow tract. A patch of pericardium was used to form the anterior wall and complete the primary cardiac repair.
