Abstract:
Objective To explore the differences of systolic segmental motion of left ventricle (LV) in patients with dilated cardiomyopathy (DCM) using illustration of the bull eye (IBE) from real-time three-dimensional echoeardiography(RT-3DE). Methods Quantitative analysis of LV segmental function was made in 43 patients with DCM by IBE. Percentage of compensated segments(PCS) was determined according to the segmental distribution by different color from IBE. Maximal exeursion(Emax),minimal excursion(Emin), average excursion (EA), standard difference of excursion(SD) and dispersion of excursion(Edis) were calculated. Results PCS in patients with DCM was 27.22%. Significant differences between DCM group and control group in Emax, Emin, EA,SD and Edis were observed( P <0. 001 ). Significant difference in segmental motion of LV was existed in patients with DCM and its distribution of motion seems tendency of irregularity. Conclnsions PCS and Edis from IBE might provide a convenient and macroscopic modality in selection of treatment and evaluation of prognosis in patients with DCM.
