Methods
Since 1989 39 consecutive patients were included (median age at first
operation 13 months). In selected cases a central aorto-pulmonary shunt
was performed as first procedure. Unifocalization procedures were
performed through a lateral thoracotomy. Correction consisted of shunt
takedown, VSD closure and interposition of an allograft between the
right ventricle and the reconstructed pulmonary artery. Postoperatively
and at follow up echocardiographic data were obtained.
