Levoatrial cardinal vein (LACV) is anomalous connection between the left atrium or pulmonary veins and any systemic vein which is derived from cardinal venous system. Presence of the levoatrial cardinal vein without a cardiac anomaly is a very rare congenital anomaly of the systemic venous return. In the literature, no LACV anomaly was found in two siblings who were asymptomatic and did not have an additional cardiac anomaly. Therefore, we present two cases ( two siblings ) the symptoms, diagnosis (the echocardiographic finding, computed tomography (CT) and aniographic images ) and treatment modalities of isolated levoatrial cardinal vein.

Objectives: The aim of this study was to analyze the frequency and results of congenital heart defects (CHD) in multipl pregnancies by fetal echocardiography. Method: This retrospective study was conducted at our hospital between January 2016 and September 2019. A total of 9440 pregnant women were enrolled in this study, including 241 were multiple pregnancies. (232 twins, 7 triplets and 2 quadruplets). Results: The prevalence of CHD was significantly higher in twin pregnancies (p=0.05). The rate of CHD was present in singletons 4.31% and twins 8.7%. There was no statistically significant difference between the two groups with respect to rate of critical congenital heart disease (p=0.32). Conclusion: Multiple pregnancies had increased congenital heart defect risk compared with singleton. Therefore, it is important to refer for fetal echocardiography when necessary.
