What are the causes coarctation of the aorta?

What are the causes coarctation of the aorta?

Narrowing: Coarctation usually occurs near the site of the pda. The PDA is a normal channel in the fetal circulation which helps blood bypass the lungs (since fetuses don't breathe). When the baby is born, the PDA constricts and closes. In some patients, the aorta also become constricted and leads to coarctation. ...Read more

What are the consequences of coarctation of the aorta?

Many complications: Some of the complications that may occur are high blood pressure, rupture of the aorta, stroke, premature heart disease and weakening or bulging of arteries in the brain. If aortic coarctation is left untreated, it could unfortunately lead to heart disease, heart failure and death. ...Read more

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

What are the most common symptoms of coarctation of the aorta?

Headache, Cold feet: Coarctation is a constriction somewhere along the path of the aorta. The symptoms largely depend on where the constriction is. You can have high pressure above and normal to low pressure below. These both cause symptoms like headache (from the high blood pressure) and exercise intolerance and pain in the legs along with cold feet (from the low pressure). ...Read more

What are the consequences of coarctation of the aorta in a child?

What are the consequences of coarctation of the aorta in a child?

High pressure: As with most things it depends on the severity and age. Coarctation is a degree of narrowing or obstruction in the arch of the aorta. As a result the part of the aorta before the obstruction usually has higher pressure than after the obstruction. So the heart and the arteries going to the head and the r arm usually have high pressure and may cause sometimes severe and irreversible complications. ...Read more

What is the presumed cause of most aneurysms of the abdominal aorta?

What is the presumed cause of most aneurysms of the abdominal aorta?

Several theories: Most common belief is that aneurysms develop due to some inherent weakness in the artery's muscular layer due to an imbalance of collagen metabolism or genetic collagen abnormalities. The only independent risk of aneurysm growth is high blood pressure and smoking. ...Read more

What does coarctation of the aorta mean?

Congenital defect: It is a narrowing of the aorta, the major blood vessel that branches off your heart and delivers blood to your body. It is usually congenital, and may range from mild to severe. Surgery may be required as a newborn if critical. It may not be detected until older, depending on severity. It often occurs along with other heart defects. It requires surgery or catheter balloon and/or stenting. ...Read more

What is the mechanism of the aortic valve?

What is the mechanism of the aortic valve?

Think swinging gate: The aortic valve is like a gate situated at the exit of the heart, that needs to swing open every time blood is ejected from the heart, and then needs to shut tight after ejection, preventing backflow of blood into the heart while it is relaxing. It is comprised of 3 cusps, like the doors of a gate, which swing outward simultaneously, and then come back to swing shut. ...Read more
