Cardiac catheterization struggles to quantify mild to moderate valvular regurgitation lacking pressure curve alterations.
Diagnostic cardiac catheterization has limitations in quantifying mild to moderate valvular regurgitation compared to severe cases.

Limits catheterization hemodynamics for mild-moderate regurgitation; leaves open need for imaging validation studies.
Selzer et al. (1963) conducted a review in Valvular Regurgitation. Diagnostic Cardiac Catheterization was evaluated. Hemodynamic diagnosis and quantitation of valvular regurgitation via cardiac catheterization presents considerable difficulties, with pressure curve alterations often absent in mild to moderate cases.
