Obstruction (Definition)

Anything that creates a blockage of the intestinal tract. You may think of the intestinal tract (stomach, small bowel, large bowel) as somewhat akin to a garden hose. If you kink the garden hose, or twist it, or block it inside, you have created an "obstruction". Most obstructions are a results of previous surgery and most of these ...Read more

Hi doctors, was just wondering what is anomalous right coronary artery?

Hi doctors, was just wondering what is anomalous right coronary artery?

See below: An anomalous right coronary artery is one that is in a different location from its usual anatomic position. It can be different in two ways: 1) where it comes off of the aorta, 2) how it gets to the parts of the heart it is supposed to supply. This can be a benign condition that's nothing to worry about, but its important to followup with your doctor to check if the location of the artery is safe. ...Read more

What could cause a high (1100+) right coronary artery score and yet after a angiogram, they find no blockage?

What could cause a high (1100+) right coronary artery score and yet after a angiogram, they find no blockage?

Great question: An angiogram is showing plaque buildup that is impacting blood flow within the lumen of the vessel but before you have that happen you can get atherosclerotic buildup within the wall of the vessel that grows outward. This can be seen by CT but can appear very minimal on an angiogram. However if you have a CT with high calcium score I recommend medical therapy for coronary disease (statin, aspirin) ...Read more

What would cause a high (1100+) right coronary artery score and yet after an angiogram, they find no blockage?

Calcicardiogram: The study you refer to scores calcium in vessel walls. This does not always correlate with coronary obstruction. It does imply the disease process is present. ...Read more

What happens if your posterior descending arterial branch of the right coronary artery diffuse proximal 60 to 80%?

What happens if your posterior descending arterial branch of the right coronary artery diffuse proximal 60 to 80%?

Depends: Many people walk around with significant blockages without knowledge or harm. If the person described has angina or evidence of ischemia on testing, a percutaneous intervention should be considered. Otherwise, forget it - but treat the underlying arteriosclerosis: statin, aspirin, Mediterranean Diet, exercise, ideal body weight, no smoking, good BP control. ...Read more

I have 3 bare metal stents in my right coronary artery. How often should these be checked by a cardiologist and how is the check done?

Based on symptoms: Scar tissue can occur around the stent. You will feel the same type of symptoms the you had prior to the stent. Your cardiologist can determine what type of testing you need to assess that. If no symptoms we usually perform a stress test every 2 to 3 years. ...Read more

Can a thrombosis of right coronary artery just lie there dormant not doing anything or nor causing harm ?

Can a thrombosis of right coronary artery just lie there dormant not doing anything or nor causing harm ?

RCA: The RCA supplies the right atrium and ventricle. A complete blockage will cause a major heart attack. A thrombosis is NOT a dormant situation. It is restricting flow. How much restriction guides therapy. At a minimum medical therapy would be necessary (aspirin, plavix, (clopidogrel) statins etc). ...Read more

Artery (Definition)

Arteries are a type of blood vessels. We can divide blood vessels into 2 categories. Arteries are high pressure vessels which deliver (red) oxygen + blood out into the body. Veins on the other hand or low pressure vessels which return (dark) oxygent - blood from the body ...Read more

Coronary Artery (Definition)

Coronary artery is the name given to the blood vessels that supply the myocardium. The word coronary was coined by the first anatomists that noticed that if you remove all muscle from the heart the remaining vessels resemble the shape of a corona or crown. ...Read more
