Unstable aortic flutter can detect aortic aneurysm with 98% accuracy. This has been shown by a study published in the journal. Nature Biomedical Engineering.
When a section of the aorta (the largest human artery) becomes enlarged to more than 1.5 times its original size, it is said to have an aortic aneurysm. In this case, the vessel wall becomes thinner and may rupture. If this happens outside the hospital, the risk of death is close to 100%. An aortic aneurysm almost always does not manifest itself until the vessel ruptures. In a new study, scientists developed the first parameter to reliably predict the risk of this dangerous event.
Mathematical analysis has shown that the risk of aneurysm rupture can be predicted by the unstable fluctuation of the aortic wall. The fact is that when blood flows through the aorta, the vessel wall begins to tremble. Researchers have found that unbalanced flutter is associated with a higher risk of aortic dilatation and rupture.
To test the new measurement (called FIP), researchers analyzed 4D flow MRI data from 117 heart disease patients and 100 healthy volunteers. FIP-based prediction was 98% accurate.
Currently, doctors estimate the likelihood of aortic rupture based on risk factors (age or smoking history) and the size of the aorta. The new parameter will make predictions more accurate.
