A method for diagnosing heart chamber remodeling LEFT AT acquired defects Mitral Valve in adult patients

摘要

A method of diagnosing the remodeling of the left heart chamber with acquired defects of the mitral valve in adult patients, characterized in that the heart is scanned from the apical access four-chamber position diastolic phase, measured end-diastolic volume of the left ventricle (Vsp) by Simpson's method measured the size of the left atrium, measured planimetric area left atrial (S) by tracing the inner contour of the cavity, the remodeling index was calculated volumes (EDI) and comparing the result with EDI set values, wherein the range of ratio values ​​RTI normal heart cavities is 2,5-5,8; when the value obtained is less than 2.5 RTI establish a diagnosis of acquired mitral valve, the I type is RTI 0.9-2.5, with a favorable prognosis operation; Type II - 0.5-0.9, with a moderately favorable prognosis operation; Type III - 0.5 and less than 0.5, with unfavorable prognosis operation, characterized in that measured transverse size of the left atrium (L) between the interatrial septum and free wall at the level of the middle third of the cavity parameters Vsp, L, S measured on one freeze frame of one cardiac cycle, the index remodeling volumes (EDI) is calculated as follows: where VV - (volume ventricule) ventricular volume equal Vsp - LVEDV left ventricle, calculated by Simpson method, VA - (volume atrium) the volume of the atria, equal to S × L, where S - planimetric area of ​​the left atrium, L- on erechny size of the left atrium.
