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 moreSee 2 more doctor answers
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 moreSee 3 more doctor answers
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 moreSee 1 more doctor answer
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 moreSee 2 more doctor answers
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 moreSee 2 more doctor answers

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
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 moreSee 1 more doctor answer
Main artery: The aorta is the main artery in the boday and is responsible for delivering blood to the rest of the body. ...Read more
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.

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 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 moreSee 2 more doctor answers
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 moreSee 2 more doctor answers
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
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 moreSee 2 more doctor answers
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
