Heart defects are susceptible to brain aneurysms

According to a study published in the American Journal of Neurology (AAN) magazine on May 4, people with common heart defects are also more likely to develop aneurysms. brain artery.

Dr. Wouter Schievink of Cedars-Sinai Medical Center in Los Angeles, California, is the lead author of the study, saying that about 2% of the population was born with congenital heart defects called narrow Aortic valve (BAV).

The aortic valve allows blood to flow from the heart to the aorta. Normally, aortic valve has three closed, open rings to coordinate blood flow.

In people with aortic valve stenosis, these valves are not fully developed during pregnancy and usually only have two rings instead of three. Many people with aortic stenosis do not have any problems, but there are many people who have symptoms that have these valves narrowed or leaked.

In the experimental study, 61 aortic stenosis patients were screened to detect symptoms of cerebral aneurysms, along with 291 people without BAV but were also screened to detect brain tumors or Symptoms of suspected stroke in the same period of time.

Results showed that six out of 61 people (accounting for 9.8%) of BAV sufferers also had cerebral aneurysm symptoms, compared with three of 291 people who were not infected with BAV (1.1%). Studies have also shown that between 0.5 and 2% of adults in general suffer from cerebral aneurysms.

Schievink said that while more research is needed to confirm this result, new findings suggest that the risk of a significant increase in cerebral aneurysms in people with aortic valve stenosis. ./.
