*'''Pulmonic stenosis'''

''Clinical Signs:''
  −
*Cyanotic; see severe exercise intolerance.

*Systolic murmur due to pulmonic stenosis +/- precordial thrill.
  −
*Polycythemia due to chronic hypoxia.
  −
  −
''Diagnosis:''
  −
*Right ventricular enlargement on radiology and ECG.
  −
*Post stenotic dilatation of pulmonary artery on radiology and pulmonary undercirculation due to right to left shunting.
  −
*Echocardiography may show right ventricular hypertrophy, paradoxical motion of interventricular septum (pressure RV>LV), visulaisation of VSD and overriding aorta.
  −
*Doppler useful to image pulmonic stenosis and VSD.
