    by  • 06/10/2013 • Cardiology

    Definition: is a valvular heart disease in which outflow of blood from the right ventricle of the heart is obstructed at the level of the pulmonic valve = reduced blood flow to lungs

    Epidemiology: accounts for 80% of R-outflow tract obstruction

    Clinical presentation: raised JVP, cyanosis, RVH, hepatomegaly, oedema, and if severe – sudden fainting / dizziness during exercise.

    Risk factors: congenital heart disease, rheumatic fever, malignant carcinoid tumour

    Investigations: echocardiography, peak pressure across the valve (>50 mmHg = intervention and replacement is warranted)

    Treatment: balloon valvuloplasty or valve replacement
