Aortic Valve Disease occurs when the aortic valve, which controls blood flow from the heart to the body, does not function properly. This can happen due to narrowing (stenosis), leakage (regurgitation), or other abnormalities. Symptoms may include chest pain, shortness of breath, and fatigue, especially during physical activity. Diagnosis typically involves imaging tests like echocardiograms, which help visualize the valve's condition. Treatment options vary based on severity and may include medication or surgical procedures, such as valve repair or replacement, to restore normal blood flow and improve heart function.
