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

Hardening of the arteries and narrowing of the arteries are same thing?

Hardening of the arteries and narrowing of the arteries are same thing?

Yes - sort of: These are terms for atherosclerosis or arteriosclerosis. This disease causes the walls of blood vessels to thick and develop what we call plaques. Eventually it can lead to narrowing of the arteries. ...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 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

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

What are the points of attachment of the chordae tendineae?

What are the points of attachment of the chordae tendineae?

Papillary muscles: The chordae tendinae attach the papillary muscles of the heart to the mitral valve and a second set also connects to the tricuspid valve. They look like thick white branches extending from the valve to the muscles. ...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

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 is tortuosity of the basilar artery and the basilar artery impresses upon the lower brain stem.?

What is tortuosity of the basilar artery and the basilar artery impresses upon the lower brain stem.?

A radiologic descrip: I'll presume you're reading off a radiologic report that involves imaging the arteries within the brain. Description that an artery is 'tortuous' means its curvier than usual, and not abnormal; basilar artery sends blood to brain stem, located in basal part of skull in back of your head; whether any clinical significance to 'impresses on the brain stem' needs to be interpreted by neurologist. ...Read more

What is the significance of stenosis of the mitral valve?

What is the significance of stenosis of the mitral valve?

It varies: Mild stenosis may casue no problems. Severe stenosis causes the pressure to increase in the left atrium, the lungs and eventually the right side of the heart. The left atrium enlarges in response to the higher pressure and the likelihood of atrial arrhythmias increases. Fluid can accumulate in the lungs causing shortness of breath and exercise intolerance. ...Read more

What is the function of the chordae tendinae?

What is the function of the chordae tendinae?

Hold valve: Think of valve as a parachute, chordae tendinae are the "ropes" that anchor the valve leaflets or cusps to the heart muscle. Heart muscle contraction pulls on these cords to close the valve, when when heart relaxes then the valve opens. They are an important part of the heart valve apparatus. ...Read more
