Echocardiograms were obtained from 16 patients with d-transposition of the great vessels proved at catheterization. These echocardiograms were compared with those obtained from 74 children who had congenital heart disease proved at catheterization but no transposition of the great vessels and those from 60 normal children. All 16 patients with transposition of the great vessels showed superimposition of the great vessels without intervening crista, and in 14 of 16 patients simultaneous recording of echoes from the semilunar valves was observed. This finding was not observed in the 74 children with other forms of congenital heart disease or in the 60 normal children. Superimposition of the great vessels with simultaneous recording of semilunar valve echoes appears to be specific for d-transposition of the great vessels.
