Pulmonary Stenosis PS

  • The Pulmonary Valve is thickened and narrowed leading to the development of abnormally high pressure in the right ventricle. The right ventricular wall becomes thickened ("Hypertrophied"). Stenosis (narrowing) of the pulmonary valve restricts flow into the pulmonary srteries. This leads to the presence of a heart "murmur". Often the narrowing is mild and does not put significant strain on the heart


    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 will usually be performed with the use of a "balloon catheter" procedure.

    'Balloon Valvuloplasty' is a procedure done using a Heart Catheter threaded up a vein 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 will usually remove the need for an operation, though if the valve cannot be adequately opened with a balloon procedure surgery may be required.
