-left ventricular contrast
+Contrast echocardiography is used to improve the picture quality and at the same time provide information on myocardial perfusion. Contrast echocardiography can save the patient for further invasive investigations. Because in addition to improving quality contrast, echocardiography provides a secure and comprehensive investigation of cardiac structure, function and coronary flow reserve.

+Contrast echocardiography is used to enhance the echogenicity of blood (better signal/noise ratio) and is used only in patients in whom no contrast has delivered (if there are 2 or more segments of LV myocardium are not to judge) any result. Contrast does the left ventricle white highlight and enhance the outline of the endocardial border, which reduces the accuracy in detection or exclusion of abnormalities increases.

-Indications for LV contrast
+==Mechanical index==
-Abnormal LV structure and function *
+Transducers generate an acoustic field by a high input (power) of emitted sound waves (vibrations). One measure of this is the mechanical index. High mechanical index destroy the contrast bubbles. Therefore, a reduction in the input of the sound waves transmitted is a necessary.
