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
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?
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?
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
Recently i had angioplasty for the second time and i still have a 45% blockage in my right coronary artery. Now what?
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 moreSee 1 more doctor answer
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 moreSee 1 more doctor answer
My doctor told me I have 70% right coronary artery blockage. How did he measure the percentage of blockage?
Can an abnormal right coronary artery lead to any problems? What if you have symptoms during exercise such as chest pain/shoulder pain?
Possibly: If the right coronary artery arises from the pulmonary artery instead of the aorta, the blood flowing through it is low on oxygen, and can cause cardiac symptoms. This almost always presents in infants and children. In later life, coronary artery problems are due to atherosclerosis, and the symptoms are typically angina. If you have any questions, see you primary physician or cardiologist. ...Read moreSee 1 more doctor answer
I have unstable angina and a 100% blocked right coronary artery. Had an angeoplasy done and the doctor did nothing after but said may just use meds ?
Situation specific: Theres data that suggests in certain scenarios medical management is equivalent to interventions like stenting. But that's a blanket statement and the reality is, it's very situation specific. Best to talk it over with your trusted cardiologist. ...Read moreSee 1 more doctor answer

Can I ride a roller coaster 3 years after having a heart attack due to blockage of the right coronary artery and getting stents implanted?
Enjoy ride: Hope you are not doing the tallest and fastest roller coaster. ...Read more
Life expectancy of a 59-year-old male, type 1 diabetic after receiving a right coronary artery stent, while having the other side of heart scarred..?
What's mean mild coronary artery disease involving the left anterior descending and the right coronary artery? It's something to worry? Heart attack?
MDs visual judgement: I would be quite wary of the assessment, likely based on a coronary angiogram. Get a copy of all the images, on a cdrom from hospital, &closely examine yourself. Do not settle for someone else's interpretation, its not their body/heart. Any narrowing (stenosis) means advanced atherosclerosis with previous plaque ruptures; clots which have fibrosed/not-cleared; narrowed the opening of the artery. ...Read moreSee 1 more doctor answer
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
