Aortic stenosis is a heart condition where the aortic valve narrows, making it harder for the heart to pump blood into the aorta. This narrowing can lead to symptoms like chest pain, shortness of breath, and fatigue, especially during physical activity. It often develops slowly over time and can be caused by age-related wear and tear or congenital heart defects. If left untreated, aortic stenosis can lead to serious complications, including heart failure. Treatment options may include medication to manage symptoms or surgical procedures like valve replacement to restore normal blood flow. Early diagnosis and management are crucial for a better outcome.
