Double switch with reversed Patrick-McGoon for corrected transposition of the great arteries with double outlet right ventricle.

A 4-year-old boy diagnosed with a double outlet right ventricle with transposition of the great arteries in a discordant atrioventricular connection. The anatomical characteristics of the ventriculoarterial relationships resulting from leftward deviation were quite similar to a mirror image of those in the malformation reported by Patrick and McGoon. Hence, it was most appropriate to perform the double switch operation associated with Patrick-McGoon's intraventricular rerouting and Senning's atrial switch. This intraventricular rerouting could be performed without damaging the conduction system because of existence of the anterior node. The cardiac catheterization 1 month after the operation showed no pressure gradient of the new reconstructed left ventricular outflow tract, good left ventricular function and no significant pressure gradient of the right ventricular outflow tract. The patient has been staying in class 1 of New York Heart Association for more than 3 years after the operation.
