Transposition of the Pulmonary Veins [PDF]
Circulation, 1958 The seriousness of incomplete transposition of the pulmonary veins has probably been underestimated in the past. Data on 11 patients is presented, including 10 with associated atrial septal defects. Common symptoms were dyspnea, fatigability, and frequent respiratory infections.

Pulmonary vein stenosis and the pathophysiology of "upstream" pulmonary veins.
The Journal of Thoracic and Cardiovascular Surgery, 2014 Surgical and catheter-based interventions on pulmonary veins are associated with pulmonary vein stenosis (PVS), which can progress diffusely through the "upstream" pulmonary veins. The mechanism has been rarely studied. We used a porcine model of PVS to assess disease progression with emphasis on the potential role of endothelial-mesenchymal transition

Morphological variations of pulmonary veins draining into left atrium: A detailed cadaveric study
National Journal of Clinical Anatomy, 2021 Introduction: During pulmonary vein isolation ablation procedure, the knowledge of number and position of pulmonary veins with thickness of posterior wall of left atrium (LA) is of invaluable significance.

Outcomes in Establishing Individual Vessel Patency for Pediatric Pulmonary Vein Stenosis
Children, 2021 The purpose of this study was to determine what patient and pulmonary vein characteristics at the diagnosis of intraluminal pulmonary vein stenosis (PVS) are predictive of individual vein outcomes.

Automatic pulmonary artery-vein separation in CT images using a twin-pipe network and topology reconstruction [PDF]
PeerJ Computer Science, 2023 Background With the wide application of CT scanning, the separation of pulmonary arteries and veins (A/V) based on CT images plays an important role for assisting surgeons in preoperative planning of lung cancer surgery.

Blood vessels and their construction in the cavities of pulmonary tuberculosis [PDF]
, 1958 First of all, we investigated the origin, the construction and distribution of the bronchial arteries and veins in adult rabbits, and then observed various changes of the blood vessels in experimental cavities and caseous foci and also studied the ...

Acquired pulmonary arteriovenous malformation associated with bronchiectasis: a case report
Journal of Medical Case Reports, 2022 Background Pulmonary arteriovenous malformations are mostly caused by congenitally abnormal shunts between pulmonary arteries and pulmonary veins.

Ultrasonic characterization of the pulmonary venous wall: echographic and histological correlation [PDF]
, 2002 Background: Pulmonary vein isolation with radiofrequency catheter ablation techniques is used to prevent recurrences of human atrial fibrillation. Visualization of the architecture at the venoatrial junction could be crucial for these ablative techniques.
