Normal Drainage, Abnormal Connection: Partial Anomalous Pulmonary Venous Connection and Sinus Venosus Atrial Septal Defect With a Net Right-to-Left Shunt

摘要

A seven-month-old girl with partial anomalous pulmonary venous connection and atrial septal defect underwent cardiac magnetic resonance for further evaluation. Anatomical images and flow quantification confirmed the diagnosis and demonstrated a commitment of the superior vena cava to the left atrium, resulting in a right-to-left shunt and pulmonary/systemic blood flow ratio of 0.85. The findings were confirmed during surgery.
