Total anomalous pulmonary venous connection (TAPVC); supracardiac type into superior caval vein (SVC)

Anomalous pulmonary venous connection (APVC) is an uncommon congenital anomaly in which pulmonary venous blood flows directly into the right side of the heart or into the systemic veins. The venous abnormality may be partial or total. Total anomalous pulmonary venous connections (TAPVCs) represent approximately 1% to 3% of major congenital heart diseases.^[1,2] The overall incidence of partial anomalous pulmonary venous connections (PAPVCs) is approximately 0.5%.^[3] Echocardiography is regarded as the preferred initial screening and diagnostic modality in patients with APVC.^[4] The purpose of our study was to compare echocardiographic features and surgical or computerized tomography angiography (CTA) results of consecutive APVC patients over the last 6 years at the Union Hospital, Huazhong University of Science and Technology, to present the imaging findings of different types of APVCs and to evaluate the diagnostic value of echocardiography in APVCs.
