Abstract Persistent left superior vena cava (PLSVC) is a relatively common
congenital venous anomaly that typically drains into the coronary sinus without
hemodynamic significance. Rarely a PLSVC drains directly into the left atrium,
forming a right-to-left shunt that can result in hypoxemia and potential paradoxical
embolism. We present the case of a 2-year-old medically complex child on chronic
mechanical ventilation with eventual diagnosis of episodic hypoxemia due to a
PLSVC draining into the left atrium with position-dependent venous flow. The lesion
was identified with contrast echocardiography and cardiac MRI. Subsequent occlusion with a vascular plug resulted in resolution of the child’s… More >
