Abstract:
Objective To investigate the value of real-time three-dimensional echocardiography timing-excursion parametric index and 17 segment volume curves index in patients with restrictive cardiomyopathy.Methods Eight patients with restrictive cardiomyopathy (proven by biopsy),twenty eight subjects with normal left ventricular(LV) function were examined by Philips iE33 with X3-1 probe.Results Parameter index of the SD and maximum difference of Tmsv of 16 segments,12 segments,and 6 basal segments(Tmax 16SD,Tmsv-12SD Tmsv -6SD,Tmsv-16Dif,Tmsv-12 Dif,Tmsv-6Dif,Tmsv 16-SD%,Tmsv 12-SD%,Tmsv 6-SD%,Tmsv 16-Dif%,Tmsv 12-Dif%,Tmsv 6-Dif%) was significantly higher in patients with restrictive cardiomyopathy than that in subjects with normal LV function(all P＜0.001).Average and maximum value and minimum of excursion was significantly lower in patients with restrictive cardiomyopathy than that in subjects with normal LV function(P＜0.001,P＜0.005,P＜0.005).And parameter index of 17 segment volume curves index showed higher sensitivity,specificity,positive predictive value and negative predictive value for diagnose restrictive cardiomyopathy.Conclusions Real-time threedimensional echocardiography can evaluate and diagnose restrictive cardiomyopathy fastly.
