Ectopic pulmonary venous drainage is a congenital heart disease, when the pulmonary veins do not empty into the left atrium but into the right atrium or into the accessory vein.

The heart is a wonderful organ, because it can pump oxygen and nutrient-rich blood throughout the body to sustain life. It works up to 100,000 times a day, each pumping 5 to 6 liters of blood (or 2,000 gallons per day).

Ectopic pulmonary veins are a congenital heart defect that occurs when the pulmonary veins do not drain into the left atrium but instead drain into another location, either the right atrium or an accessory vein. This condition causes increased pressure on the right side of the heart and reduces the amount of oxygen-rich blood reaching the left side of the heart to nourish the body. The basic treatment is to correct the anatomical abnormality, bringing the pulmonary veins into the left atrium.

The lungs are the central organs of the respiratory system. Understanding the anatomy of the lungs and pleura helps patients better understand this organ and have effective measures to protect the lungs from pathogens.
