I have my 2 year son with giant coronary aneurisms, he had kawasaki disease when he was 5 months old. what are the chance of regression inthe future?

Aneurysm regression: Hi Harold, I'd suggest you take a look at some of the statistics regarding coronary aneurysm regression that are reported in these pertinent studies. http://www.ncbi.nlm.nih.gov/pubmed/1432415 http://circ.ahajournals.org/content/94/6/1379.full

Discuss with cardiol: This question is best answered by his cardiologist. He knows your son's history. There are many variables to consider.

It depends: It depends on the size, location and type of aneurysm. Also aneurysms that occur in children less than one year of age are more likely to resolve. These aneursyms need to be followed by the pediatric cardiologist very closely.

50-65%: By giant aneurysm I assume you mean over 8mm. The rate of regression overall is up to 67% however the larger or giant aneurysms have a lower rate. Usually about 50% chance of regression. In the meantime the usual treatment, besides close monitoring is aspirin and warfarin.

Ask cardiologist: Please speak to your child's cardiologist.. ' Good luck.

Giant aneurysms : Giant aneurysms are usually defined as being over 8mm in size. They unlike small aneurysms do not go away. They place the patient at risk for other cardiac problems. This is a patient who needs to be followed closely by a pediatric cardiologist with frequent echos. Longterm survival is good but it is so important to have good follow up care.
