pulmonary vein noun : any of usually four veins comprising two from each lung that return oxygenated blood from the lungs to the superior part of the left atrium, that may include three veins from the right lung if the veins from all three lobes of the right lung remain separate, and th...
In subject area:Pharmacology, Toxicology and Pharmaceutical Science Secondary pulmonary hypertension is the term used to describe pulmonary vascular disease that is the result of disorders that primarily alter the structure or function of the lung or diseases that affect the lung circulation as part ...
What does pulmonary vein flow analysis add to the assessment of left ventricular hemodynamics?In the evaluation of patients with heart disease, two-dimensional and Doppler echocardiography are established noninvasive techniques to assess left ventricular structure and function. To characterize left ...
Mechanisms underlying ectopic activity in the pulmonary vein (PV) which triggers paroxysmal atrial fibrillation are unknown. Although several studies have suggested that calcium signalling might be involved in these arrhythmias, little is known about calcium cycling in PV cardiomyocytes (CM). We found ...
The jet of mitral regurgitation is directed into the right upper pulmonary vein and augments the forces in that lung that promote fluid retention. Pleural and pericardial effusions develop in patients with left heart failure. In edema, the subpleural interstitial pressure rises sufficiently to create ...
The causative factors include thrombi, air, amniotic fluid, and fat. In PE, gas exchange is impaired due to the decreased return of deoxygenated blood to the lungs. More than 90% of PEs are complications of a deep vein thrombosis (DVT) of the lower extremity. Some individuals are ...
Multiscale image‐based modeling and simulation of gas flow and particle transport in the human lungs Improved understanding of structure and function relationships in the human lungs in individuals and subpopulations is fundamentally important to the futur...

These results suggest that the vasoconstrictive effects of ET-1 are exerted mainly through ETA receptor in the proximal segments of the pulmonary artery and vein, whereas its effects in the distal segments are mediated by ETA and ETB receptors in normal rats. ETA receptors that increase in ...
