Evaluation of left ventricular systolic function and dyssynchrony in fatients with myocardial infarction by triplane tissue tracking imaging

Objective To evaluate left ventricular systolic function and dyssynchrony in patients with myocardial infarction(MI) by triplane tissue tracking imaging(Triplane-TTI).Methods Thirty healthy controls and thirty MI patients were included,the LVEF was obtained from Simpon's method.Basal and middle segments of 6 walls of the left ventricle(12 Segments) were studied.Peaking displacement(D) and Time to peak displacement(Td) were measured with Triplane-TTI.Then we calculated the maximal difference in Td(Td-maxD) and the standard deviation of Td(Td-sD).Results Compared with healthy controls,parameters LVEF and D of the MI patients were significantly lower and the dyssynchrony indexesTd-maxD,Td-sD were much longer than those in control subjects(P0.05).LVEF is correlated negatively with the dyssynchrony indexes Td-maxD,Td-sD(r=-0.671,-0.559,P0.05).Conclusion The systolic function damage and dyssynchrony of left ventricular is common in MI patients,and LV dyssynchrony LVEF.We concluded that Triplane-TTI is a new and accurate methods in assessment of left ventricular systolic function and dyssynchrony.
