Determination of the severity of mitral valve regurgitation is necessary in patients with valvar heart disease in order for physicians to make rational choices in modes of therapy. Numerous methods exist to aid the physician in this assessment, including the nature and severity of symptoms, findings on physical examination, routine studies such as the chest roentgenogram, and more recently, echocardiography, pulse Doppler analysis, and radionuclide left ventriculography. However, cardiac catheterization remains the most accurate way to quantitate mitral valve regurgitation. Catheterization provides further qualitative information by assessment of the height of the V wave on the pulmonary artery wedge pressure tracing and the amount of regurgitant dye from the left ventricular cineangiogram. When Fick or dye dilution determination of net forward cardiac output is combined with quantitative left ventricular angiography, the regurgitant volume and regurgitant fraction can be calculated.

Each of the methods used to evaluate mitral valve regurgitation, including . . . [Full Text PDF of this Article]
