[Late results after Rastelli correction in transposition of the great arteries (author's transl)]

From 1974 to 1978, 11 patients underwent a Rastelli correction in transposition of the great arteries with VSD and obstruction to the pulmonary artery. 2 patients died, a mortality of 18%. All patients received a Hancock-conduit. On the average of 30 months after the operation, a complete heart catheterisation was performed. In 6 patients--55%--there was no or only a mild gradient between the RV and AP (Gradient under 40 mm Hg). 3 patients (27%) developed a considerable obstruction to the pulmonary artery (gradient over 70 mm Hg) proximal, valvular, or distal. Subaortic obstruction was not observed. 3 of the 9 patients had a residual VSD, detectable by oxymetry, 1 with a flow ratio of 1.8, which required surgery (successfully closed).
