Coexistence of transposition of the great arteries, coarctation of the aorta, and bilateral pulmonary artery hypoplasia.

ABSTRACT

Transposition of the great arteries is the most common cyanotic CHD in newborns. This CHD, in which the aorta arises from the right ventricle and the pulmonary artery from the left ventricle, is often accompanied by one or several defects such as atrial septal defect or patent foramen ovale, ventricular septal defect and patent ductus arteriosus, which allow the transition between both parallel circulations. Rarely, the disease may be accompanied by left ventricular outflow tract obstruction (subpulmonary obstruction) and coarctation of the aorta.We present a highly complicated and unusual transposition of the great arteries patient with critical aortic coarctation and hypoplastic pulmonary arteries with abnormal outflow and course.
