Fetal Diagnosis of Dextroposition, Left Pulmonary Artery Sling, Partial Anomalous Left Pulmonary Artery, and Aortic Coarctation

• LPA sling is a rare anomaly definable by fetal echocardiography. • LPA sling is frequently associated with significant respiratory morbidity and mortality. • Fetal diagnosis should prompt planning for postnatal management at a pediatric center. • We present a fetal case of dextroposition, partial LPA sling, and aortic coarctation. • Progressive dextroposition was an indicator for the presence of an LPA sling.
