Title: Assessment of left ventricular systolic and early diastolic synchrony in patients with dilated cardiomyopathy using real-time three-dimensional echocardiographic volume-time curves
Abstract: Objective To evaluate the left ventricular systolic and early diastolic synchrony in patients with dilated cardiomyopathy(DCM) using real time three-dimensional echocardiography(RT-3DE) volume-time curves(VTC).Methods Thirty-seven patients with DCM(DCM group) and 27 healthy subjects(control group) were examined with RT-3DE.VTC of two groups were analyzed.Standard deviation of time to minimal systolic volume(Tmsv-SD),and standard deviation of time to early diastolic volume(Tedv-SD) about 16,12,6 segments were obtained and standardized using R-R interval as systolic dyssynchrony index(SDI) and early diastolic dyssynchrony index(DDI).Results ①Compared with those of the control group,SDI and DDI were higher in DCM group.②SDI and DDI had negative correlation with LVEF in DCM group.Conclusion There was left ventricular systolic and early diastolic dysynchrony in patients with dilated cardiomyopathy.
