Prenatal Diagnosis of Persistent Left Superior Vena Cava is Associated with Coarctation of the Aorta - A Case Report

A singleton pregnant woman was found to have persistent left superior vena cava (PLSVC) of the fetus at 22 weeks by ultrasound. Follow-up scans revealed PLSVC, dilated coronary sinus, dominant right heart, some pericardial effusion, and hypertrophy of the right ventricular wall. The woman had an abdominal delivery at 34 weeks due to rupture of membranes. The baby was found to have coarctation of the aorta postnatally and had aortic reconstruction at 31 days of age. A prenatal ultrasound finding of PLSVC might be associated with coarctation of the aorta and it warrants specialist follow-ups and complete workup of echocardiography prenatally and postnatally.
