If your coronary artery origin/anatomy is seen on echocardiogram does this most likely rule out congenital coronary anomalies?

If your coronary artery origin/anatomy is seen on echocardiogram does this most likely rule out congenital coronary anomalies?

No: Coronary arteries are not typically seen on an echocardiogram. When they are, only the very beginning of the artery where it arises from the aorta may be seen. An echocardiogram is not a good test for looking at coronary arteries. ...Read more

Artery (Definition)

Arteries are defined as blood vessels which carry blood away from the heart (to either the body or lungs). Arteries: higher pressure, thicker walls, stretch (pulse) with each heart contraction & deliver blood to the arterioles which control the flow to individual capillaries. Veins are blood vessels which carry blood from capillaries back to the heart (body to right heart; ...Read more

What is the ramus coronary artery?

What is the ramus coronary artery?

The third artery: Normally the main coronary blood vessel has two branches--the left anterior descending artery and left circumflex, but some people have a third branch termed intermediate artery or ramus-coronary artery--see picture. The incidence is some where between 10-30%. This can cause some confusion in ekg interpretation if this vessel is blocked/causing a heart attack. Consult doc. Good luck. ...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 is the location of the coronary arteries?

What is the location of the coronary arteries?

Picture this: The coronary arteries branch off from the walls of the aorta, and dive down into the outer layer of the heart mucle. On the left side, the left main artery branches into the left anterior decending (lad), which runs down the front wall of the heart, and the circumflex, which runs around the lateral wall. On the right, the right coronary artery runs along the bottom wall of the heart. ...Read more

What is the importance of the coronary arteries?

blood to heart: The coronary arteries supply blood to the heart muscle itself. There are usually 3 - the left anterior descending, circumflex, and right coronary. Closure or blockage of one of these main arteries, or a branch vessel, from cholesterol or a clot, causes a heart attack or angina (chest pain). ...Read more

What causes thrombosis of the coronary arteries?

What causes thrombosis of the coronary arteries?

Arterioclerosis: Arteriosclerosis or plaque buildup in the wall of the coronary arteries will narrow the lumen to the point where there is flow restriction, then clot formation. The plaque may rupture, allowing a flap-like effect, blocking the lumen, resulting in clot formation. Trauma may cause a separation of the layers of the wall, and this dissection results in clot formation. ...Read more

How do coronary artery spasms differ from angina?

How do coronary artery spasms differ from angina?

Definition and cause: Angina isused to describe heart pain that specifically comes from an obstruction to the heart muscle's blood supply. The causes can be due to mechanical obstruction like a plaque, a clot or a combination. The heart arteries are muscular and can constricy and relax. Constriction (often found where there is clot and inflammation) of the arteries, or spasm, can contribute or in some cases cause angina. ...Read more
