title: Congenital levojuxtaposition of the right atrial appendage. Association with persistent truncus arteriosus, type 4.
abstract: Congenital levojuxtaposition of the right atrial appendage is a rare malformation most commonly associated with a transposition of the great arteries. We report a case of levojuxtaposition of the right atrial appendage associated with a persistant truncus arteriosus, type 4. Juxtaposition of the atrial appendage is a sign of severe cyanotic congenital heart disease, and this is best diagnosed by a selective right atriogram or superior venacavogram.
