Cardiology · Pathway 38
Murmurs
Key points
- Ejection systolic: aortic stenosis · pulmonary stenosis · HOCM · ASD · Fallot's.
- Holosystolic (pansystolic): mitral/tricuspid regurgitation (high-pitched, blowing) · VSD (harsh).
- Late systolic: mitral valve prolapse · coarctation of aorta.
- Early diastolic: aortic regurgitation (high-pitched, blowing) · Graham-Steel (pulmonary regurgitation).
- Mid-late diastolic: mitral stenosis (rumbling) · Austin-Flint (severe AR). Continuous machine-like: PDA.
Decision points in this pathway
- When in the cardiac cycle is the murmur?
- Early or mid-late diastolic?
- Ejection, holosystolic or late systolic?
