“…Because this drainage site is unlikely for the levoatriocardinal vein. Similarly, in cases where PLSVC drains into the left atrium via the unroofed CS, unroofed CS and ASD facilitate the differential diagnosis in favor of PLSVC, since they are unusual for LACV [29][30][31].…”

“…Please note that LACV may accompany LOLs (yellow arrow shows hypoplastic left heart, f), may be seen together with PLSVC, may be associated with any venous structure in the cardinal system not only left brachiocephalic vein, and in some cases, may have blood flow in the craniocaudal direction between pulmonary and systemic circulations cannot regress due to increased pressure in the left atrium and remain as LACV in the postnatal period. However, in the presence of complex CA, the diagnosis of PLSVC should be considered mainly [29][30][31].…”

Persistent left superior vena cava (PLSVC) is the most common thoracic venous anomaly and may be a component of the complex cardiac pathologies. While it is often asymptomatic, it can lead to significant problems such as arrhythmias and cyanosis. Besides, it can cause serious complications during vascular interventional procedures or the surgical treatment of cardiac anomalies (CA). The clinical significance of PLSVC depends on the drainage site and the accompanying CA. In this article, we will describe the epidemiology, embryology, and anatomic variations of PLSVC. Possible accompanying CA and heterotaxy spectrum will be reviewed with the help of multidetector computed tomography (MDCT) images. Radiological pitfalls, differential diagnoses, and the clinical importance of PLSVC will be highlighted.

“…The levoatriocardinal vein is a rare entity distinct from anomalous pulmonary venous drainage, in which the primary abnormality is the absence of connection of one or more pulmonary veins in the left atrium. 8 The LACV is a collateral venous vessel that connects the left atrium or one of the pulmonary veins to the systemic venous system, usually The innominate vein. 9 In a case series reported by Bernstein et al, 25 LACV patients were studied.…”
