An analysis of patients requiring unifocalization revision following midline unifocalization for pulmonary atresia with ventricular septal defect and major aortopulmonary collaterals†

Midline unifocalization has been developed for the surgical treatment of pulmonary atresia with ventricular septal defect and major aortopulmonary collateral arteries. All patients will eventually require reoperation because of the presence of a conduit, and some patients may also require revision of the distal unifocalized bed. The purpose of this study was to analyse the need for unifocalization revision following midline unifocalization.
