Cardiac catheterization may be indicated to assess which heart condition related to valves?

• A. Valvular heart disease
• B. Liver failure
• C. Renal dysfunction
• D. Pulmonary embolism

Answer: (A)

Cardiac catheterization is used to quantify valve function directly, which is essential when assessing valvular heart disease. It provides precise hemodynamic data across the valves: measuring transvalvular gradients and chamber pressures helps determine how severely a valve is stenotic or regurgitant. By injecting contrast into the valve or ventricle, clinicians can visualize the regurgitant jet and, with calculations like the Gorlin formula, estimate valve area to gauge stenosis severity. This invasive but highly specific information complements noninvasive imaging and is especially helpful when planning valve repair or replacement or when there’s concern for coexisting coronary disease before intervention. Liver failure, renal dysfunction, or pulmonary embolism involve different pathways and are not assessed primarily for valve performance with this procedure, though cath may be used in broader hemodynamic evaluation in some contexts.
