Unusual Form of Truncus Arteriosus Associated With 22q11 Deletion

Images in cardiovascular medicine. Unusual form of truncus arteriosus associated with 22q11 deletion.

A25-year-old woman was referred at 31 weeks’ gestation for prenatal echocardiography because routine obstetrical sonography had detected a cardiac malformation. Pregnancy to that point had been normal. Four-chamber and great-vessel views allowed the diagnosis of truncus arteriosus with an abnormal dilatation of the pulmonary tree (Figure 1 and Movie I). An in situ hybridization study performed ...

Truncus arteriosus communis associated with chromosome 22q11 deletion.

OBJECTIVES The purpose of this study was to clarify characteristics of truncus arteriosus communis associated with chromosome 22q11 deletion (del 22q11). BACKGROUND DiGeorge syndrome and conotruncal anomaly face syndrome are associated with del 22q11 (hemizygosity). In 30% of cases, truncus arteriosus communis is associated with the deletion. METHODS Fifteen consecutive patients with truncu...

Truncus arteriosus communis. Unusual case associated with transposition.

A child with truncus arteriosus communis, characterized by the posterior origin of an individualized pulmonary trunk is presented. This relationship between the great arteries is unusual in truncus arteriosus communis and the spatial orientation resembles that seen in transposition of the great vessels. A brief discussion is proposed about a proper terminology in this type of complex anomaly.

Sirenomelia Associated with Truncus Arteriosus

Syrenomelia sequence is a rare (incidence of 1: 60000 births) [1,2] lethal pattern of congenital anomalies characterized by a number of hallmark skeletal anomalies including fusion of the lower extremities or a single lower limb, bilateral renal agenesis or dysgenesis with absent or hypoplastic renal arteries, oligohydramnios and the presence of aberrant vasculature. Prenatal sonographic detect...
