Truncus arteriosus with double aortic arch: A rare association

Özet

Truncus arteriosus (TA) is a congenital heart defect often diagnosed in neonatalperiod; it represents 0.7% of all congenital heart lesions. The pulmonaryarteries originate generally above the coronary ostium. Aorto-pulmonary andinterventricular defects are believed to represent an abnormality of conotruncalseptation. TA is classified into four types, according to Van Praagh andColette Edwards. Some of congenital heart defects may be associated withTA, such as aortic interruption. In literature, TA with a double aortic archis observed as a very rare condition. We present here a newborn diagnosedwith a combination of TA type 1 and double aortic arch.
