COMMENTS ON STATION 1

DIAGNOSIS: PULMONARY STENOSIS (PS)

These findings suggest a diagnosis of pulmonary stenosis and in particular with the stenosis being at the level of the valve (in view of the click). In the exam diagnosis of this murmur would be entirely dependent on your being able to localise a systolic murmur to the pulmonary area. The click is an added bonus which will clinch the diagnosis but may not be picked up (apparently best heard at the third left intercostal space in expiration.) Textbooks also suggest the presence of a right ventricular heave (this will be felt at the left sternal border).

Pulmonary stenosis is an example of an acyanotic heart condition (critical pulmonary stenosis as a neonate has a different pathophysiology due to shunting and is a cyanotic heart condition). Do not forget to listen for a possible ventricular septal defect, which would indicate tetralogy of Fallot. Other valve or hole defects may also be present, e.g. atrial septal defect or patent ductus arteriosus in a more complicated cardiac lesion. Do not forget to look for a scar in the mid-axillary line; this may represent a scar after a Blalock-Taussig shunt (palliative procedure).

Important differentials to exclude are an atrial septal defect (also an ejection systolic murmur in the pulmonary area but you should hear a wide, fixed, split second heart sound – heard only by experts!) and aortic stenosis (louder in the aortic region and generally associated with a carotid or suprasternal thrill). There may be a suprasternal thrill with PS; a carotid thrill is diagnostic of aortic stenosis. If the murmur is soft, with no radiation, consider the possibility that this is an innocent pulmonary flow murmur.

Please see table below for investigations and management of PS.
