Abnormal Connection of the Ductus Venosus to a Dilated Coronary Sinus Imaged by Prenatal Echocardiography: Case Report.

We describe a case of a fetus with an ectopic connection of the ductus venosus to a dilated coronary sinus that was diagnosed at ShengJing Hospital of China Medical University. A dilated coronary sinus was initially detected with prenatal echocardiography. Neither a persistent left superior vena cava nor an anomalous pulmonary venous connection was present. After comprehensive examination, we discovered that the ductus venosus had an abnormal course draining into the coronary sinus. The postnatal outcome of this fetus was good. Once a dilated coronary sinus is confirmed, further ultrasound evaluation should be performed to search for a potential cause.
