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

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 is coarctation of the aorta?

What is coarctation of the aorta?

Narrowing of alrta: Coarctation is a narrowing of the main vessel (aorta). It leads to hypertension and increased work for the heart. Untreated it leads to stroke coronary disease and death. Therapeutic options are surgery or catheter therapy. ...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

What is the function of the bicuspid valve in the heart?

What is the function of the bicuspid valve in the heart?

You mean malfunction: The aortic valve has 3 parts or leaflets. When its called bicuspid it has only 2 leaflets. This can be congenital or aquired. If two of the cusps fuse over time is called functional bicuspid vs congenital. Either way it creates an un natural flow across the valve and over time damage the valve. Most often the valve will need replace depending on age diagnosed.Most congen bicuspids will need repla. ...Read more

What's the purpose of the coronary arteries?

What's the purpose of the coronary arteries?

Feed heart muscle: In humans usually two main coronary arteries come off the aorta to feed the heart muscle. The right coronary feeds the right side of the heart and some of the muscular wall between the two sides. The left coronary divides into the left anterior descending artery and the circumflex coronary artery. The arteries bring oxygen and food to heart muscle cells. ...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 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

Abnormality of the mid inferior wall of the heart?

Abnormality of the mid inferior wall of the heart?

RCA or LCX: In 80% of people, the mid-inferior wall is supplied by the right coronary artery. In 10%, it's supplied by the left circumflex and in 10% there are contributions from both arteries. A focal abnormality in that location in a 60 yo man is statistically likely to be due to blockage in 1 or both of those arteries. The area is likely to be scarred or hibernating. ...Read more

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
