title: [Non-invasive assessment of left ventricular diastolic function disorder using Doppler echocardiography].
abstract: Symptoms of a variety of cardiac diseases may well be caused predominantly by diastolic dysfunction, which appears to be one of the first detectable cardiac alterations. Diastole represents a complex interplay of multiple factors. Doppler echocardiography offers a noninvasive and relative simple method to assess left ventricular volumetric filling rates. The pulsed-wave Doppler method enables us to measure mitral flow velocities. Two distinct mitral flow velocity patterns have been recognized for situations with diastolic dysfunction. The pattern of delayed relaxation was reported in primary and in secondary left ventricular hypertrophy, myocardial ischemia and infarction and in dilated cardiomyopathy. The pattern of increased stiffness was described in constrictive pericarditis, restrictive processes and in heart transplant rejection. Doppler echocardiography has shown to be a helpful diagnostic tool, but a number of factors influencing mitral flow measurements have to be considered in each case, as there are age, heart rate, loading conditions and mitral regurgitation. Further studies are needed with respect to future control of therapeutic interventions and prognostic statements.
