Partially anomalous pulmonary venous connection treated by interventional catheterization.

A young man had anomalous connection of the veins draining the upper lobe of the left lung to both a left-sided vertical vein and the left atrium. The ratio of pulmonary to systemic flows was 1.7 : 1, and he was symptomatic with evidence of volume overload of the right heart. He was successfully treated by percutaneous placement of an Amplatzer ductal occlusion device into the vertical vein.
