Total anomalous pulmonary venous connection, also known as total anomalous pulmonary venous return, is a rare cyanotic congenital heart defect in which the pulmonary veins drain into the right side of the heart instead of the left, as is usually seen. This can happen within the heart (intracardiac) where it drains into the coronary sinus or ...
Pulmonary vein isolation by transcatheter ablation can restore sinus rhythm. [4] As atrial fibrillation becomes more persistent, the junction between the pulmonary veins and the left atrium becomes less of an initiator and the left atrium becomes an independent source of arrhythmias. [6] Pulmonary vein isolation ablation technology has used ...
Carlon et al reported the first superior cavo-pulmonary anastomosis between the right pulmonary artery and azygos vein, demonstrated an increase in pulmonary blood flow in dogs. [17] The Glenn group at Yale worked on several strategies to create anastomoses between the superior or inferior vena cavae to the right or main pulmonary arteries.
Pulmonary vein stenosis can be congenital or acquired. [6]A rare abnormality that accounts for 0.4% of congenital heart diseases, congenital pulmonary vein stenosis results from the common right or left pulmonary vein failing to integrate into the left atrium (LA) during the vessel's embryonic development, obliterating the pulmonary veins partially or completely on one or both sides.

The pulmonary circulation is a division of the circulatory system in all vertebrates. The circuit begins with deoxygenated blood returned from the body to the right atrium of the heart where it is pumped out from the right ventricle to the lungs.
The hemiazygos vein and the accessory hemiazygos vein, when taken together, essentially serve as the left-sided equivalent of the azygos vein. [2] That is, the azygos vein serves to drain most of the posterior intercostal veins on the right side of the body, and the hemiazygos vein and the accessory hemiazygos vein drain most of the posterior intercostal veins on the left side of the body.
