A physical exam and review of your medical history are important first steps in diagnosing aortic valve stenosis. If you have stenosis but no symptoms, your doctor will likely find the condition during a routine exam or a checkup for another health problem. A distinctive heart murmur is usually the first clue that leads a doctor to suspect aortic valve stenosis.
Check your pulse. A weak pulse may mean that there is narrowing of the heart valve.
Listen to your heart and lungs for abnormal sounds. A soft whooshing or humming sound (murmur) heard through a stethoscope is an important finding that often points to heart valve disease. Abnormal sounds in the lungs can mean fluid buildup in the lungs that is caused by heart valve disease.
Look at your legs and feet. Swelling in the legs and feet may be a sign of heart failure.
An echocardiogram (echo) can confirm your symptoms and tell your doctor how severe stenosis is, how well your left ventricle is working, and whether there are problems with other valves.
It's also an important test to help monitor aortic valve stenosis over time.
Recommended frequency for checking aortic valve stenosis1
Chest X-ray. It may show calcium buildup in the valve, an enlarged left ventricle, or fluid buildup if you have developed heart failure. In some cases, the aorta may be enlarged just beyond the aortic valve.
