Factors determining early outcomes after the bidirectional superior cavopulmonary anastomosis.

BDG procedure can be performed safely with acceptable mortality. Age at presentation, pulmonary artery size and VIS were not related to mortality. Younger patients had similar outcomes but a longer hospital stay. Patients with preserved antegrade pulmonary blood flow had higher saturations. Those undergoing BDG without cardiopulmonary bypass had lower inotropic scores.
