Analiza porównawcza ilościowej oceny funkcji skurczowej lewej komory z zastosowaniem metod echokardiograficznych

Abstract

Introduction. The aim of the study is to compare echocardiographic methods in the assessment of left ventricular systolic function. Material and methods. In a group of 84 patients (45 men; mean age 59 ± 11 years), left ventricular ejection fraction (LVEF) was quantified using the biplane Simpson method; triplane method, 2D speckle tracking echocardiography (2D STE) and semiautomatic 4D Auto LVQ algorithm in 3D echocardiography. Results. The highest correlation was demonstrated for the parameters of longitudinal strain in 2D speckle tracking with the LVEF (regardless of the echocardiographic method of its measurement). The strongest correlation was between systolic longitudinal strain in 2D STE and left ventricular ejection fraction in 4D Auto LVQ. There was no satisfactory correlation between global systolic deformation parameters in 4D Auto LVQ and LVEF values calculated using the Simpson two-plane method in 2D and 3D echocardiography. Conclusions. Modern echocardiographic methods are becoming helpful in assessing the systolic function of the left ventricular, and the semiautomatic algorithms of 3-dimensional echocardiography allow to improve the diagnostic value.
