A narrowing of the aorta that restricts blood flow from the heart to the body, potentially causing serious cardiovascular problems.
From Greek 'aorta' (the main artery) plus 'stenosis' (narrowing). This medical term developed as physicians recognized and described various causes of aortic narrowing, including congenital defects and acquired lesions.
Aortostenosis is like putting a kink in a giant fire hose—when the body's main artery narrows, the heart has to pump much harder, and if the narrowing is severe, oxygen delivery to vital organs can become dangerously inadequate.
