- Carey-Coombs murmur of acute rheumatic fever is a sign of active mitral valvulitis
- Soft, early diastolic murmur usually varies from day to day.
- Higher pitch than the diastolic rumbling murmur of established mitral stenosis.
- Pure severe mitral regurgitation
- Increased flow across the valve
- Sometimes with a short diastolic murmur with a S3
- Left atrial myxoma
- Tumor plop
- Graham Steel murmur of pulmonary regurgitation
- Increases with inspiration
- Austin-Flint murmur
- A presystolic (late diastolic) murmur in patients with aortic insufficiency
