The Mustard operation for transposition of the great arteries (TGA). Technical considerations

Among the late complications described after Mustard's procedure, obstructions of the pulmonar veins. SVC or IVC have been the most serious ones. We consider that these complications are mostly related to the size and shape of the baffle and also to the way in which it is sutured into place. No such complications have hitherto been encountered in our patients. We feel that the technique described may help in the standardization of the Mustard procedure as well as tailoring of the baffle. Thereby this procedure is more easily reproduced and the frequency of late complications possibly reduced.
