Graham Steell murmur
Appearance
A Graham Steel murmur is a heart murmur typically associated with pulmonary regurgitation. It is a high pitched early diastolic murmur heard best at the left sternal edge in the second intercostal space with the patient in full inspiration.
The murmur is heard due to a high velocity regurgitant flow across the pulmonary valve; this is usually a consequence of pulmonary hypertension.
