Dizygotic twins concordant for truncus arteriosus

Dizygotic twins concordant for truncus arteriosus.

Persistent truncus arteriosus (TA) is an uncommon congenital cardiovascular malformation, which comprises between 0.4% and 4% of all congenital heart defects. Occurrence of TA in siblings has been reported infrequently. Twins concordant for isolated TA appear to have been reported only once previously. In this paper, we describe dizygotic twin females who were concordant for isolated TA.

Truncus Arteriosus

We have encountered difficulty in recognizing and identifying clinically true truncus arteriosus with pulmonary arteries (type 1) because of its resemblance to correctable cardiac defects such as patent ductus arteriosus, aortic-pulmonic defect, and ventricular septal defect. In the present report we are presenting clinical information on 14 patients with this anomaly, both to supplement the sc...

Dizygotic Twins Concordant for Down Syndrome: Implication for Establishing a National Birth Defect Registry in Iran

The prevalence of Down Syndrome (DS) has increased in association with increasing maternal age (1). The prevalence of multiple births, particularly dizygotic births has also increased in association with increasing maternal age (2). Surprisingly , the risk of DS in twins is significantly lower than in singletons due to early fetal loss of DS in multiple pregnancies, particularly in pregnancies ...
