Aortic Stenosis

  • The Aortic Valve is thickened and narrowed leading to the development of abnormally high pressure in the left ventricle. The left ventricular wall becomes thickened ("Hypertrophied"). 

    Stenosis (narrowing) of the aortic valve restricts flow into the aorta. This leads to the presence of a heart "murmur". Often the narrowing is mild and does not put significant strain on the heart.


    However the narrowing frequently worsens with growth. If the obstruction is severe, symptoms may develop, or the heart may show evidence of "strain".  The valve may require treatment to open it up. This may be surgical or with the use of a "balloon catheter" procedure.

    Balloon Valvuloplasty for Aortic Stenosis

    'Balloon Valvuloplasty' is a procedure done using a Heart Catheter threaded up an artery from the leg. A balloon at the tip of the catheter is placed across the valve and is then inflated to 'Open Up' the narrow valve.  This procedure may allow surgery to be delayed until  the patient is older, but will usually not remove the need for an operation at a later stage.
