pul·mo·nar·y veins

[TA]
four veins, two on each side, conveying oxygenated blood from the lungs to the left atrium of the heart. Those from the left lung and the inferior vein from the right lung are lobar veins, each draining a single lobe with the corresponding name; the right superior pulmonary vein drains both the superior and middle lobes of the right lung.
See also: left inferior pulmonary vein, left superior pulmonary vein, right inferior pulmonary vein, right superior pulmonary vein.
Synonym(s): venae pulmonales [TA]

Two sequential applications are performed to create a box lesion by a continuous encircling line around the 4 pulmonary veins. Two times encircling box lesion set is the procedure ablation endpoint.
Contributing factors to diagnostic errors: Diagnostic error was most common with the mixed variety of TAPVR (seen in 80%) with three (75%) cases having only one pulmonary vein draining separately while the other three pulmonary veins drained within the confluence.

The standard of care in AF ablations is pulmonary vein isolation (PVI)--the application of energy to create lines of scar tissue around the pulmonary veins in the left atrium to block unwanted electrical signals that trigger AF.
Wilkoff also notes that high blood pressure and kidney disease can contribute to poor pulmonary vein health, including the formation of blood clots in your pulmonary veins.
Before the procedure, a 12 leads ECG recording, polysomnography, transthoracic and transesophageal echocardiography and computer-tomography (CT) of the pulmonary veins were performed in all patients.
