What are the dangers of ectasia?

Hello,

Welcome to icliniq.com.

The LAD vessel, that is left anterior descending artery is showing ectasia which means it is slightly enlarged in caliber, but there are no blockages. Also, other things which are mentioned is description of the vessel, the way they are supplying the heart but there are no blockages or any abnormalities. According to it, right-sided vessel is giving long branches and supplying a large part of the heart, but there are no abnormalities. So overall, other than the enlargement of the vessel, there is no abnormality and it is not a cause for his chest pain. Does he smoke? If yes, he should quit it gradually. The report does not appear worrisome. Thank you.

Hello,

Welcome back to icliniq.com.

By enlargement, I referred to dilatation. Although they have not mentioned the details of it, from the description, it appears to be non-severe. You should get CT films reviewed or review on console by a local cardiologist. Ectasia has multiple causes like inflammatory diseases in childhood like Kawasaki disease, sometimes these are congenital problems, associated with other diseases like Ehler Danlos syndrome, due to trauma, in older patients due to atherosclerosis which is not there in your vessels. The risk associated with these is the risk of clot formation and blockages if severe ectasias are there then the risk of rupture. However, it is a rare complication. These may regress with time in some individuals. Normally, the heart has two arteries supplying the right and left. They supply their own territories, and right is considered dominant usually. In your case, right is giving some extra branches to the area which is usually supplied by the left. So, it is called super dominant. This is just a normal variation and nothing to worry about it. Now, there appear to be no complications at this moment in your vessels. The chest pain usually due to blockages occurs on exertion and relieves with rest. I guess you do not have that kind of pain. I think the best course of action for you at this moment is you should get aneurysm images reviewed by a local doctor in order to ascertain its severity. Also, discuss with a radiologist and ask them for severity. Also, get one echo done to look for heart function and rules out the possibility of other diseases. Also, the local doctor will examine you rule out the possibility of other associated diseases. Further, a test may be done accordingly. Sorry for long post.
