right inferior pulmonary vein

The right inferior pulmonary vein is a pulmonary vein that drains oxygenated blood from the inferior lobe of the right lung and returns it to the left atrium.

It is located in the right thorax, traveling from the inferior lobe of the right lung to drain into the inferior portion of the left atrium at the right pulmonary hilum.

Its function is to carry oxygenated blood from the inferior lobe of the right lung back to the left atrium, where it contributes to the systemic circulation.

Pulmonary vein stenosis, anomalous pulmonary venous return, and complications of atrial fibrillation ablation may be associated with the right inferior pulmonary vein.

CT angiography and cardiac MRI are used to evaluate the right inferior pulmonary vein anatomy and its connection to the left atrium, especially prior to electrophysiology procedures.
