Abstract
-
We experienced a case of persistent left superior vena cava draining into the common atrium in a fetus of 26-year-old primigravida. Persistent left superior vena cava is derived from the left cardinal vein. This anomalous vessel usually drains into the right atrium via the coronary sinus and has no physiologic significance. Much less frequently, the left superior vena cava drains directly into the left atrium and it is associated with complex heart anomalies such as atrial septal defect, absence of coronary sinus, double outlet right ventricle, transposition of great arteries and asplenia syndrome. Fetal echocardiography showed an abnormal vessel draining into common atrium in a fetus with complex heart anomalies. It had a different direction from right superior vena cava or pulmonary veins in its traveling. We report a case with autosy findings.
