The Features of echocardiography in assessment of right chambers in health and focal myocardial infarction
Ischemia of the right ventricle occurs in half of patients with acute myocardial infarction inferior wall of the left ventricle to the development of hemodynamic expressed associated with severe clinical outcomes. Development dysfunction of the right ventricle in patients after myocardial infarction increases mortality on 24-34%. Information about normal sizes and at the focal lesions of right chambers are few and contradictory. These and other data, presented in the review, suggest the need to study and optimize methods for assessing right ventricular function. The most affordable method of noninvasive evaluation is echocardiography, based on the data of which will be determined the most informative indicators to assess the function of right chambers in normal and focal lesions of the myocardium various locations. Visual evaluation of the contractility of the right ventricle and techniques for the assessment its global systolic function enought subjective and depend on the experience of the researcher. For the quantitative assessment systolic function of the right ventricle is used tissue velocity imaging and specle tracking.
