    Causes

    Verified Expert

    • Aortic valve stenosis is caused by genetic factors or certain health conditions which may have an impact on proper functioning of aortic valve. The causes may include:
    • Congenital heart defect
    • Calcification of the valves- If calcium deposits on the aortic valve, it prevents proper opening or closing leading to this condition
    • Infective conditions like rheumatic fever
    • Risk factors include
    • Age - more common among older age people
    • Uncontrolled high blood pressure, diabetes or high cholesterol
    • Infection that may affect heart
    • Chronic kidney disease

    Symptoms

    Verified Expert
    Contact your provider if experiencing new, severe, or persistent symptoms.

    Symptoms may show up when narrowing of the valve is severe and may include:

    • Heart murmur (abnormal swooshing sound produced by the heart as it beats)
    • Chest pain
    • Tiredness after exertion
    • Shortness of breath after exertion (exercise or moving)
    • Heart palpitations

    Is aortic stenosis a progressive disease?
    Aortic stenosis is in general a progressive disease. Progressive calcification of the valve results in progressive narrowing and a pressure overload phenomenon in the heart. This can cause thickening of the heart muscle and stiffening. In early phases, this can cause shortness of breath and chest discomfort.

    Diagnosis

    Verified Expert
    One or more of these tests may be recommended by your medical provider.
    Physical conditions are thoroughly examined by listening to the heart for any abnormal sounds and followed by tests to confirm and assess the severity of the condition.

    Common tests & procedures

    Echocardiogram: This test provides video images of the heart.

    Electrocardiogram (ECG or EKG): Measures the electrical activity of the heart; can detect abnormal heart rhythms.

    X-ray: Chest X-ray is taken to eliminate other possible conditions that could be causing the symptoms.

    CT scan: CT scan of the heart provides 3D images which aid in looking for possible abnormalities.

    Magnetic resonance imaging (MRI): MRI scan of the heart provides highly detailed images of the heart so as to check for the possible abnormalities.

    Cardiac catheterization: This test uses dye to highlight any blockages in the heart.
