Tricuspid stenosis cardiac catheterization

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
