[Morphological and functional study by echocardiography].

Echocardiography can measure various parameters of left and right ventricle function during either systolic or diastolic phase. Many parameters of cardiac function are obtained by B-mode, M-mode and Doppler images. Recently, invasive techniques, such as trans-esophageal echography, intra-luminal echography, contrast echography of the left ventricular muscle and stress echography were developed. In the future, 3-dimensional echography and acoustic tissue characterization will be developed for quantitative measurement of cardiac functions.
