Abstract: Objective To investigate the value of real-time three-dimensional echocardiography(RT-3DE) timing-excursion parametric index and 17 segment time-volume curves index in patients with leftventricular noncompaction(LVNC). Methods Ten patients with LVNC (proven by MRI) ,twenty subjects with normal LV function were examined by Philips iE33 with X3-1 probe. Results Parameter index (including Tmsv 16-SD,Tmsv 12-SD,Tmsv 6-SD,Tmsv 16-Dif,Tmsv 12-Dif,Tmsv 6-Dif,Tmsv 16-SD%,Tmsv 12-SD%, Tmsv 6-SD%, Tmsv 16-Dif%, Tmsv 12-Dif%, Tmsv 6-Dif%) of 17 segment time to minimal systolic volume was significantly higher in patients with LVNC than that in subjects with normal LV function( all P＜0.05). Average and minimum value of excursion was significantly lower in patients with LVNC than that in subjects with normal LV function ( P＜0.05). Conclusions RT-3DE with timeexcursion parameters and 17 segment of time- volume curve parameters can rapidly and accurately evaluate left ventricular systolic synchrony in patients with LVNC.
