Abstract
We present a case of a staged "double switch" complex biventricular repair in a newborn with heterotaxy, dextrocardia [S, L, L], double outlet right ventricle, double outlet left atrium with right-dominant unbalanced complete atrioventricular canal, L-transposition of the great arteries, and aortic arch hypoplasia. A staged double switch approach allowed safe biventricular correction of a rare complex cardiac defect without residual lesions before 1 year of age.
