Pulmonary vein anatomy is highly variable among atrial fibrillation patients. [5] 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 ...
Pulmonary embolism is occlusion or partial occlusion of the pulmonary artery or its branches by an embolus, usually from the embolization of a blood clot from deep vein thrombosis. [10] It can cause difficulty breathing or chest pain, is usually diagnosed through a CT pulmonary angiography or V/Q scan , and is often treated with anticoagulants ...
Add cardiac skeleton. Inferior vena cava more wide. Add aorta in bottom. Add source veins of superior vena cava. Brachiocephalic trunk more wide and separated. Added shadows. Left main pulmonary artery with its first division. 07:02, 2 June 2006: 650 × 650 (26 KB) Yaddah: Diagram of the human heart, created by Wapcaplet in Sodipodi. Cropped by ...
This concept is generally attributed to an article by West et al. in 1964, [1] but was actually proposed two years earlier by Permutt et al. [2] In this article, Permutt suggests "The pressure in the pulmonary arteries and veins is less at the top than at the bottom of the lung. It is quite likely that there is a portion of the lung toward the ...

structures of the cardiovascular system, including the heart and great vessels, which include the thoracic aorta, the pulmonary artery and all its branches, the superior and inferior vena cava, the pulmonary veins, and the azygos vein; structures of the respiratory system, including the diaphragm, trachea, bronchi and lungs [1]
The section shows: 1) the opened ventricles contracting once per heartbeat—that is, once per each cardiac cycle; 2) the (partly obscured) mitral valve of the left heart; 3) the tricuspid and pulmonary valves of the right heart—note these paired valves open and close oppositely. + (The aortic valve of the left heart is located below the ...
Blood vessels function to transport blood to an animal's body tissues. In general, arteries and arterioles transport oxygenated blood from the lungs to the body and its organs, and veins and venules transport deoxygenated blood from the body to the lungs. Blood vessels also circulate blood throughout the circulatory system.
