What is a proximal LAD lesion?

What is a proximal LAD lesion?

Hear this out loudPauseProximal left anterior descending coronary artery (LAD) lesions often supply a high percentage of the left ventricular myocardium, compared to proximal lesions in the circumflex or right coronary arteries.

What is distal right coronary artery?

Hear this out loudPauseDistal: from middle segment to origination point of the posterior interventricular artery, where the posterior interventricular sulcus meets the atrioventricular groove on the base of the heart.

What is a Type C coronary lesion?

Hear this out loudPausetype C. diffuse. excessive tortuosity of proximal segment. extremely angulated, >90º inability to protect major side branch.

What is distal stenosis?

Hear this out loudPauseIn a curved artery segment with two moderate stenoses of the same size, the distal stenosis causes a larger pressure drop and a more disturbed flow field in the poststenotic region than the proximal stenosis does.

How long does a LAD stent last?

Hear this out loudPauseHow long will a stent last? It is permanent. There is just a 2–3 per cent risk of narrowing coming back, and if that happens it is usually within 6–9 months. If it does, it can potentially be treated with another stent.

Is LAD blockage serious?

Hear this out loudPauseA narrowing or blockage in the LAD is more serious than narrowing or blockage in the other arteries. Bypass surgery usually is the best choice for a blocked LAD. If the LAD is not blocked, and there are no other complicating factors, stents are more likely to be used, even if both of the other arteries are blocked.

What are the 2 main branches of the right coronary artery?

Hear this out loudPauseThe right coronary artery divides into smaller branches, including the right posterior descending artery and the acute marginal artery.

What percentage of artery blockage is normal?

Hear this out loudPauseA moderate amount of heart blockage is typically that in the 40-70% range, as seen in the diagram above where there is a 50% blockage at the beginning of the right coronary artery. Usually, heart blockage in the moderate range does not cause significant limitation to blood flow and so does not cause symptoms.

Proximal left anterior descending coronary artery (LAD) lesions often supply a high percentage of the left ventricular myocardium, compared to proximal lesions in the circumflex or right coronary arteries.

What is a lesion in the coronary artery?

Some of these complex lesions in coronary vessels include bifurcation lesions, calcified lesions, chronic total occlusions, unprotected left main coronary artery lesions, ostial lesions, or stenosis of the saphenous vein graft.[1] Each of these lesions presents unique challenges, and the approach to such lesions is …

Distal: from middle segment to origination point of the posterior interventricular artery, where the posterior interventricular sulcus meets the atrioventricular groove on the base of the heart.

What is severe coronary lesions?

Coronary artery disease develops when the major blood vessels that supply your heart become damaged or diseased. Cholesterol-containing deposits (plaques) in your coronary arteries and inflammation are usually to blame for coronary artery disease. The coronary arteries supply blood, oxygen and nutrients to your heart.

What are the 3 types of lesions?

They tend to be divided into three types of groups: Skin lesions formed by fluid within the skin layers, such as vesicles or pustules. Skin lesions that are solid, palpable masses, such as nodules or tumors. Flat, non-palpable skin lesions like patches and macules.

What is a lesion in a vessel?

Vascular lesions are relatively common abnormalities of the skin and underlying tissues, more commonly known as birthmarks. There are three major categories of vascular lesions: Hemangiomas, Vascular Malformations, and Pyogenic Granulomas.

The right coronary artery divides into smaller branches, including the right posterior descending artery and the acute marginal artery.
