Levoatriocardinal Vein and Mimics: Spectrum of Imaging Findings

AJR. American Journal of Roentgenology

This article focuses on the embryology, hemodynamics, and CT and MRI features of levoatriocardinal vein. Levoatriocardinal vein, a form of pulmonary systemic connection, is most commonly seen in left heart obstructive lesions, providing an alternative egress for pulmonary venous blood. Levoatriocardinal vein can be differentiated from other more common anomalies, such as anomalous pulmonary venous return, persistent left superior vena cava, and dilated left superior intercostal vein, by its distinctive imaging features.

Birth Defects

Birth defects encompass structural and functional alterations that occur during embryonic or fetal development and are present since birth. The cause may be genetic, environmental or unknown and can result in physical and/or mental impairment. Here is the latest research on birth defects.
