pulmonary vein

The pulmonary veins take blood to the left side of the heart.

The remaining blood is returned to the heart via the pulmonary veins.

In humans there are four pulmonary veins, two from each lung.

A multiple anomaly of the human heart and pulmonary veins.

When this happens, the pressure backs up into the pulmonary veins and the lungs.

In this image, the heat is destroying tissue at the base of the pulmonary vein.

The disorder is sometimes called misalignment of the pulmonary veins.

From there, blood flows back through the pulmonary vein to the left atrium.

In the left atrium, the junction is at the pulmonary veins.

They were able to isolate all pulmonary veins in 100% of patients in both groups.

The most common form is an ablation of the pulmonary veins and surrounding tissue.

The pulmonary veins carry relatively oxygenated blood from the lungs to the heart.

This increase in volume or pressure backs up to the left atrium and then to the pulmonary veins.

Therefore, the number of pulmonary veins opening into the left atrium can vary between three and five in the healthy population.

The pulmonary vein returns the now oxygen-rich blood to the left atrium.

The lesions form a "box-like" pattern around all four pulmonary veins behind the heart.

In these animals, the left atrium still serves the purpose of collecting blood from pulmonary veins.

The veins going into the left atrium are the pulmonary veins.

The blood from the lungs travels through the pulmonary veins to the left atrium, increasing the pressure there.

The pulmonary veins, returning blood from the lungs, drain into this extra "third atrium."

Rather than misaligned, the pulmonary vein is malpositioned in a site somewhat different from its normal position.

In all veins apart from the pulmonary vein, the hemoglobin is desaturated at about 75%.

Blood is oxygenated in lungs and returns to the left atrium through pulmonary veins.

This region is known as pulmonary vein antrum.

They were able to isolate only 8% of pulmonary veins using the system, having to complete procedures manually in the remainder.
