[Diagnosis of left ventricular diastolic dysfunction by Doppler echocardiography].
Left ventricular(LV) diastolic dysfunction with preserved LV systolic function is common among patients with hypertension, especially with LV hypertrophy. Doppler echocardiography is one of the most useful clinical tools for the evaluation of diastolic function. Mitral inflow and pulmonary venous flow velocities are used not only for the assessment of diastolic function but also for predicting prognosis. Recently, tissue Doppler echocardiography has been also applied to evaluate diastolic function. Accurate assessment of diastolic function has been demonstrated by measuring both mitral annulus and mitral inflow velocity. In this article, We review the diagnosis of diastolic dysfunction by Doppler echocardiography using mitral inflow velocity, pulmonary venous flow velocity and mitral annulus velocity measured by tissue Doppler imaging.
