Abstract:
Objective To summarize the prenatal ultrasonographic characteristics of unroofed coronary sinus( URCS) for improving the prenatal echocardiography diagnostic accuracy of URCS . Methods The retrospective review for prenatal ultrasonogram of 7 fetuses was applied ,which were diagnosed as URCS . The prenatal ultrasonographic characteristics of 7 fetuses with URCS were reviewed and comparatively analyzed with postpartum autopsy findings or postnatal echocardiography . The relevant literatures referring to the prenatal diagnosis of URCS were reviewed . The experience of prenatal diagnosis of URCS were summarized . Results In 7 cases with URCS ,5 cases of completely URCS were associated with right atrial isomerism syndrome and confirmed by postpartum autopsy ,and 2 cases of partially URCS were only with persistent left superior vena cava and confirmed by postnatal echocardiography . The karyotype analysis of 2 cases of partially URCS on amniotic fluid was normal . Conclusions There are some characteristic signs in ultrasonic features of URCS . URCS can be diagnosed by prenatally ultrasonography . A long axial section of the coronary sinus is the most important view for prenatal ultrasonic diagnosis of U RCS .
