Aortic Valve Stenosis Explained

Aortic valve stenosis is a condition that can develop due to both congenital and acquired factors. Causes may include infections, endocarditis, rheumatic fever, or age-related calcification. These conditions can lead to calcification, contraction, and fusion of the aortic valve leaflets. As a result, the valve fails to open properly, causing a narrowing known as aortic stenosis.

Understanding the Impact on Blood Flow

When the aortic valve becomes narrowed, the heart struggles to pump blood through the restricted opening into the aorta. This results in high-velocity blood flow that can be detected through echocardiography. Medical professionals can also measure pressure differences across the valve, typically observing higher pressure in the left ventricle compared to the aorta.

Symptoms and Complications

Over time, this increased workload on the heart can lead to cardiac strain. Patients may experience symptoms such as chest discomfort, dizziness, shortness of breath, and fatigue. These signs often worsen with physical activity and can significantly affect quality of life if left untreated.

It's important for individuals diagnosed with aortic valve stenosis to work closely with their healthcare provider. Treatment options vary depending on the severity of the condition and the patient's overall health. Management strategies may include lifestyle adjustments, medications to alleviate symptoms, or more advanced interventions like valve repair or replacement.
