D-transposition of the great arteries with right sided pulmonary hypoplasia.

Unilateral pulmonary agenesis or aplasia (UPA) in combination with congenital heart defects is rare and has not been reported in connection with transposition of the great arteries. This case demonstrated dextroposition of the fetal heart, and subsequent scans could not clearly visualize the right pulmonary artery. UPA should be considered in the workup and counseling for a family in the setting of fetal heart malposition, as there is a significant clinical impact. [ABSTRACT FROM AUTHOR]
