Pulmonary veins (Venae pulmonales)
Educational content only — not medical advice.
Anatomy
Four veins (superior and inferior per lung) draining into the left atrium with oxygenated blood — unique among veins — and their atrial sleeves are the classic electrical origin of atrial fibrillation targeted in ablation.
Clinical notes
Total anomalous pulmonary venous connection gives cyanosis with anomalous venous drainage; their injury threatens en-bloc avulsion during open-heart left-atrial surgery.
