93452 Left hrt catheter with ventrclgrphy
Also known as: Left heart cath, LHC, left ventriculography
Left heart catheterization with ventriculography, measuring left ventricular pressures, assessing ventricular function, and evaluating mitral regurgitation through contrast injection.
In Plain Language
left heart tube with fluid pictures; left heart pressure and pumping test; heart squeeze measurement
Clinical Context
Used to assess left ventricular function, evaluate valvular disease (especially mitral regurgitation), measure cardiac output, and detect wall motion abnormalities. Standard component of diagnostic cardiac catheterization in suspected structural heart disease.
