Unifocalization with pericardial roll technique in pulmonary atresia with ventricular septal defect and major aortopulmonary collateral arteries.

Single-stage complete repair of the ventricular septal defect, pulmonary atresia, and major aorticopulmonary collateral arteries has better results than unifocalization with a shunt. In terms of nonvaluable raw material, the use of the pericardial roll technique is a considerable alternative for unifocalization.
