Diagnosing Aortic Valve Stenosis

Overview

Aortic stenosis is a condition where the valve of the aorta, which controls blood flow from the heart to the rest of the body, becomes narrowed or stiff. This makes it harder for the heart to pump blood through the aortic valve, which can cause the heart to work harder and lead to symptoms like chest pain, shortness of breath, or feeling faint.

To diagnose aortic valve stenosis, several examinations, tests, and procedures are typically performed:

• Physical examination: During a physical examination, a healthcare provider, such as a cardiologist, will carefully examine your body for any physical signs of aortic stenosis. They may listen to your heart for abnormal sounds.
• Echocardiogram: An echocardiogram is commonly ordered to view the condition of the heart chambers and heart valves. It uses sound waves to create images of your heart. This test helps look at the structure and function of the aortic valve and can diagnose aortic stenosis.
• Imaging tests:
  • Chest X-ray: A chest X-ray can show if the heart is enlarged or if there is any calcium buildup on the aortic valve.
  • Chest magnetic resonance imaging (MRI) or computed tomography (CT) scan: These imaging tests provide detailed images of your heart and can help see how severe the aortic stenosis is.
• Cardiac catheterization: Cardiac catheterization is an aggressive procedure that uses dye to check the pressure and flow of blood through the heart chambers. It can help determine the how severe the aortic stenosis is and identify any additional heart problems in people who have symptoms such as chest pain or shortness of breath.
• Blood tests: Blood tests may be done to check for inflammation of the heart valve (endocarditis) or rheumatic fever, which can be linked with aortic stenosis.
• Stress test: A stress test is performed to evaluate how well your heart functions under physical stress. It can help determine if there are any limitations caused by aortic stenosis.

Diagnosing aortic valve stenosis involves collaboration between different healthcare providers. Your primary care provider (PCP) may refer you to specialists such as cardiologists or heart valve centers for further evaluation and management.
