Aortic stenosis most often occurs either at an advanced age due to calcium buildup over time or from birth due to a congenital heart defect. Aortic stenosis is a condition in which the opening of the aortic valve narrows, restricting blood flow from the heart to the rest of the body. The American Heart Association estimates that over 20% of older Americans have aortic stenosis, referring to it as a condition âcommon in people over age 65.â¹ Despite its prevalence, many patients may not be aware of aortic stenosis and the associated risks it presents. Left untreated, a severe case can cause chest pain, difficulty breathing, and potential heart failure. Therefore, educating at-risk patients about detection and symptoms is critical.
