One-stage unifocalization and palliative right ventricular outflow tract reconstruction.

We report a successful case of one-stage unifocalization concomitant with palliative right ventricular outflow tract reconstruction for pulmonary atresia and ventricular septal defect with major aortopulmonary collateral arteries and central pulmonary arterial absence. Through a median sternotomy, one-stage unifocalization was accomplished using autologous pericardial conduit and no prosthetic material. To achieve an adequate pulmonary blood flow, the right ventricular outflow tract was reconstructed so that it would be 70% of the normal pulmonary annular diameter, while the ventricular septal defect was left open. One-stage unifocalization concomitant with palliative right ventricular outflow tract reconstruction is considered to be a good surgical option for selected patients with these diseases.
