Coronary steal syndrome is a condition that occurs due to dilation of coronary arteries in the presence of coronary artery disease, which is when there’s a partial or complete blockage in the lumen of another coronary artery.
Now, the heart pumps out blood for all of our organs and tissues to use - but the heart also needs blood.
So it also pumps blood to itself, through the coronary arteries on the outside of the heart.
And coronary arteries are linked to one another through teeny tiny blood vessels called collateral vessels, which are normally in an inactive state, meaning blood doesn’t flow through them.
In this context, collateral circulation may become active. For example, let’s say two coronary arteries,
A and B, are linked by a collateral vessel, and coronary artery B has developed a block.
