Question 1

Heart blood flow: Coronary arteries bring oxygenated blood to the heart.  Coronary veins returned that same blood to the venous circulation.  Both types of vessels sit on the surface of the heart.

Question 2

what is the function of coronary arteries and veins?

Accepted Answer

Arteries/veins: Every organ needs a supply line (artery) and discharge (vein). Think of your faucet and drain. The coronary arteries supply the heart muscle with oxygen and energy, the veins carry off the metabolic waste.

Question 3

what is the average longevity for artificial veins used in coronary by pass?

Accepted Answer

8-12 years: Veins are said to last about 10 years.  Arteries such as internal mamary or radials can last much longer.  Ofcourse if you take good care of them, with no smoking, exercising, watching diet, keeping LDL <70, keeping sugars down, keeping weight down etc then I have patients whose vein bypasses have stayed open for 20+ years!
