How does coarctation of the aorta develop in the heart?

How does coarctation of the aorta develop in the heart?

Not in the heart: Coarctation of aorta by definition does not occur in the heart. It is usually in the descending segment of the aorta and it is congenital (person is born with it). The exact location is variable, sometimes it involves the aorta proximal to the take off of the left subcalvian (artery to the left arm) and at times distal to it. It is essentially a narrowing of the lumen of the artery. ...Read more

Aorta (Definition)

The aorta is the largest artery in the body, leaving directly from the left ventricle of the heart to supply blood to the entire body. It is made of elastic tissue layers called "intima" and is subject to damage by high blood pressure, smoking, cholesterol, ...Read more

How is coarctation of the aorta diagnosed in babies?

How is coarctation of the aorta diagnosed in babies?

Suspected by exam: Coarc can be suspected by exam (deminished pulses in legs vs rt arm). A cardiac ultrasound may identify the defect or a cardiologist may confirm the defect on a cardiac cathiterization. ...Read more

Why coarctation of aorta in infantile, cause passes of the blood from pulmonary artery to the aorta through pda?

Why coarctation of aorta in infantile, cause passes of the blood from pulmonary artery to the aorta through pda?

Plumbing!: Blood must get to the body, else the fetus would not survive. The same is true once the baby is born. In utero, blood flows from pulm artery (pa) to aorta (ao) normally. Once born, the blood continues to flow this way so that blood can get to the body. When the PDA closes, the child becomes very sick. ...Read more

How does blood get to your legs in case of coarctation of the aorta?

How does blood get to your legs in case of coarctation of the aorta?

Bypass channels: The fetus/baby developed & is more or less normal in appearance at birth.That would only occur with the bodies ability to bypass the narrowing of a coarctation by channeling needed blood flow though other blood vessels(collaterals). A kid may go for a few years before the coarctation is discovered. ...Read more

How does coarctation of the aorta impact blood pressure in a patient?

How does coarctation of the aorta impact blood pressure in a patient?

Kidney's: Coarctation leads to decreased blood flow in the lower body. The kidney's sense the blood flow and release hormones to regulate blood pressure. If kidney blood flow is low, they release hormones to raise BP and vice versa. And after time, the blood vessels in the body respond to the high blood pressure with abnormal changes of their own. ...Read more

What complications can accompany the coarctation of the aorta?

What complications can accompany the coarctation of the aorta?

Several: Aortic coarctation is associated with hypertension (high blood pressure). This can develop even years later, after successful surgical correction, due to a diffuse dysfunction of cells lining artery walls. This can also affect coronary arteries (causing atherosclerosis), and the adjacent (non-coarcted) aorta, with risk of aneurysm formation or dissection of the aorta wall. ...Read more

Does any one know what causes the coarctation of the aorta in people?

Abnormal embryology: By definition coarctation of the aorta is a abnormality of vascular embryology. At birth flow is adequate for the limited activity i the new born and early toddler years, but as children age, their growing bodies and activity out grows the narrowed aorta's ability to supply enough blood fast enough to keep up. ...Read more

Which is more dangerous, a hole in the heart or coarctation of the aorta?

Which is more dangerous, a hole in the heart or coarctation of the aorta?

Apples/oranges: Since there are variations in the size of any hole or the amount of tightness in any coarctation the question cannot have a simple answer. Some holes close without treatment, some produce heart failure without treatment. Some coarctations need urgent surgery while others can go years without treatment. ...Read more

Why does coarctation of the aorta lead to cerebral aneurysm?

Why does coarctation of the aorta lead to cerebral aneurysm?

Possibly: Coarctation of the aorta may lead to increased hydrostatic pressure in the vessels leading to the brain and therefore may pose a risk for cerebral aneurysm formation. If you have other risk factors, i would consider screening, but please see a neurosurgeon or neurologist about this. Refer to the brain aneurysm center for women website for more information.

Why does a PDA not occur in the right branch of the pulmonary artery?

Why does a PDA not occur in the right branch of the pulmonary artery?

PDA: It occurs between descending thoracic aorta and PA. The descending thor aorta is well to the left of the right branch of the PA. I couldn't find a variant reported in the literature with involvement of the right PA branch. There may be an embryologic explanation but I didn't find it. ...Read more

Can you cure coarctation of the aorta?

Can you cure coarctation of the aorta?

Can Correct: No congenital heart disease can be "cured". We can fully correct some types though, and coarctation is one of those. But we can never make the heart/vessel the same as if the lesion never occurred (which is the definition of cure). Again, semantic but important point because anyone with coarctation should have life-long follow-up with a cardiologist. ...Read more

When is coarctation of the aorta diagnosed?

When is coarctation of the aorta diagnosed?

It depends: Coarctation is usually detected routinely by noting a marked discrepancy in blood pressure between the arms and legs. This frequently is part of a work-up for severe hypertension--i.e. Resistant to medications, or occuring in an unusually young patient--which is a result of the obstruction to blood flow through the aorta (with build-up of pressure in the arms, where BP is routinely measured). ...Read more

How does the build up of plaque in someone with atherosclerosis cause the hardening of the arteries?

How does the build up of plaque in someone with atherosclerosis cause the hardening of the arteries?

Not the same things: Plaque buildup (atherosclerosis) in the arteries can make them less flexible, but the old term "hardening of the arteries" (arteriosclerosis) is usually attributed to a decrease in flexibility of the vessel wall even without any plaque present. It is more related to the collagen/structure of the vessel wall themselves. The utility of this term is waning as medicine advances. ...Read more

Does coarctation of the aorta have any influence on the lymph drainage in an infant?

Does coarctation of the aorta have any influence on the lymph drainage in an infant?

Not usually: Simple coarctation shouldn't have any influence on lymph drainage at all. The systems are completely different. However there are a few syndromes that mess with things in the mediastinal area, the central cavity where the heart lays, that can affect both. However, they usually come with a host of other abnormalities. ...Read more

Exercise increases the size of the heart, hypertrophy. How does this differ from cardiomyopathy and damage to the heart?

Exercise increases the size of the heart, hypertrophy. How does this differ from cardiomyopathy and damage to the heart?

Hypertrophy/cardiomy: Just like skeletal muscle will increase in muscle mass to incresae strength of contraction .This is a compensatory response to increase the force of contraction. However, as the heart muscle increases in size it everntually will decrease the size of the heart chamber (ventricle) and decreases the volume of blood in the ventricle. ...Read more

How does a valvular stenosis affect the right and left sides of the heart?

How does a valvular stenosis affect the right and left sides of the heart?

Stenosis: It depends on which valve is stenotic. Mitral stenosis increases pressure in the lungs and right heart. Aortic stenosis is a pressure overload of the left ventricle. Pulmonary and tricuspid stenoses are rarer. ...Read more
