Overview
While echocardiography remains the diagnostic imaging modality of choice, cardiac catheterization is useful to evaluate tricuspid stenosis when the results of the non-invasive testing are insufficient, particularly among patients who are being evaluated for other conditions such as mitral stenosis and pulmonary hypertension.
Cardiac Catheterization
During diastole, there is a gradient between the right atrial (RA) and right ventricular (RV) diastolic pressure (RA is higher than RVEDP). A large a wave may be seen on the RA tracing.
- Cardiac cathertization:
- In the older pre-surgery population, this may be necessary in order to assess concomitant artery disease.
- Cathertization of the right heart:
- Used as a tool to evaluate the gradient across the valve and valve area
- Used in diagnosis of associated congenital defects
- Cathertization of the left heart:
- Useful when assessing aortic and mitral valves in patients with rheumatic disease
