Normally the aorta attaches to the left ventricle which pumps oxygen-rich blood through it. 正常情况下,主动脉与左心室相连,而左心室负责泵出富氧血液。 In an overriding aorta, the aorta has moved forward directly over the hole between the ventricles. This ...
The right ventricle is a thin, highly trabeculated structure that is triangular in form and, on gross inspection, appears to be wrapped around the left ventricle. It has three well-differentiated components with specific structure and function. The inlet portion extends from the tricuspid valve to...
Left-sided heart failure : results from abnormalities on the left side of the heart (left ventricle, aortic valve , mitral valve ) Right-sided heart failure : results from abnormalities on the right side of the heart (right ventricle, tricuspid valve , pulmonic valve) Left- and right-sided ...
When a heart attack occurs in the left ventricle (left lower pumping chamber of the heart), a scar forms. The scarred area is thin and can bulge out with each beat (an aneurysm). A heart surgeon can remove the dead area of heart tissue or the aneurysm. ●Heart transplant: A heart...
Previous experiments has shown energy drinks high in caffeine (咖啡因) change the way the heart beats and could increase the risk of potentially deadly heart rhythm problems.In healthy adults who consumed the drinks,the left ventricle-which pumps blood around the body-was contracting harder,and ...
Left-sided heart failure means your left ventricle does not work correctly. It may not fill with blood as it should, or it may not pump blood out to your body properly. Left-sided heart failure can cause swelling in your lungs that leads to breathing problems.What is right-sided heart ...
Left-sided heart failure. This is the most common type. The left side of the heart, called the left ventricle, does most of the pumping. In left-sided heart failure, the left ventricle can't pump as much blood. The extra blood pools in the pulmonary veins—blood vessels that carry bloo...
The low-pressure circuit from the heart (right atrium and right ventricle), through the lungs, and back to the heart (left atrium)constitutesthepulmonary circulation. Passage of blood through the left atrium, bicuspid valve, left ventricle,aorta, tissues of the body, and back to the right atr...
This treatment for angina uses a laser to make channels in the heart muscle and left ventricle in order to let more oxygen-rich blood into the heart. It’s not well-understood why this procedure eases chest pain, but it isusually usedin place of bypass surgery, angioplasty, or stenting if...
What does a broken heart syndrome X-ray look like? Imaging tests often show a distinctive shape of the left ventricle — the heart's main pumping chamber. Its pumping ability is weakened, causing it to bulge or balloon. The shape is similar to that of a jar with a wider base and narro...
