Aortic valve stenosis

Aortic valve stenosis is a narrowing of the aortic valve opening that restricts blood flow from the heart. It develops gradually and may cause no symptoms until it is severe. An MRI may show changes in the aortic root and valve area consistent with narrowing. Finding aortic valve stenosis early allows for monitoring and surgical planning before the heart muscle is significantly affected. Echocardiography is the primary tool for valve assessment, however MRI can show aortic root dimensions and associated structural changes.
