Overview
Differential Diagnosis
The heart murmur of tricuspid stenosis must be differentiated from that of other valvular diseases. However, it should be noted that tricuspid stenosis can co-exist with other valvular diseases such as tricuspid regurgitation or mitral valve abnormalities. Differential diagnosis of tricuspid stenosis include:
- Aortic stenosis: The murmur of aortic stenosis is harsh and best heard at the right second intercostal space.
- Mitral regurgitation: The murmur of mitral regurgitation is blowing, soft and best heard at the apex.
- Mitral stenosis: The murmur of mitral stenosis is mid-diastolic, rumbling, and best heard after the opening snap.
- Tricuspid regurgitation: The murmur of tricuspid regurgitation is blowing, holosystolic, and best heard over the fourth intercostal area at left sternal border.
Tricuspid stenosis must be differentiated from other diseases that cause similar clinical presentation, such as:
