[Heart valve diseases].
Although valvular stenosis may be evaluated adequately by measuring transvalvular pressure gradients with Doppler echocardiography and cardiac catheterization, these methods have failed to provide reliable and accurate quantification of valvular regurgitation. In recent years the development of magnetic resonance imaging has broadened the diagnostic spectrum in cardiology, since it allows assessment of ventricular volumes without geometrical assumptions and the non-invasive quantification of blood flow within the heart and great vessels. The purpose of this overview is to evaluate "established" diagnostic tools and to show the capabilities of magnetic resonance imaging in the assessment of valvular heart disease.
