Abstract:
Objective To evaluate left and right ventricular function by real-time three-dimensional echocardiography in patients with heart transplantation.Methods Fourteen patients with heart transplantation ( rejection)[12 male,2 female,mean age (49.21±17.91)],twenty four patients with heart transplantation (no rejection) [21 male,3 female,mean age (40.11±12.57)],and fifty one subjects with normal left ventricular function [26 male,25 female,mean age (43.69±14.81) ] were examined by Philips iE33 with a X3-1 probe.Results Right ventricular stroke volume (RVSV) and right ventricular ejection fraction (RVEF) in heart transplantation (including no rejection and rejection) was reduced compared with subjects with normal heart function (all P<0.05),but right ventricular end-diastolic volume (RVEDV) and right ventricular end-systolic volume (RVESV) were no significantly different between heart transplantation and subjects with normal heart function (all P>0.05),but the volume and function of right ventricle were no significantly different between rejection heart transplantation and no rejection heart transplantation.Parameter index of 17 segment including standard deviation (SD) and maximum difference(Dif) of 16,12 and 6 segment time to minimal systolic volume(Tmsv 16-SD,Tmsv 16-Dif,Tmsv 12-SD,Tmsv 12-Dif,Tmsv 6-SD,Tmsv 6-Dif),and the percent of SD and maximum difference 16,12 and 6 segment time tominimal systolic volume [Tmsv 16-SD(%),Tmsv 16-Dif(%),Tmsv 12-SD(%),Tmsv 12-Dif(%),Tmsv 6-SD(%),Tmsv 6-Dif(%)] was significantly higher in patients with heart transplantation (rejection) than that in subjects with normal heart function and in patients with heart transplantation (no rejection)[except Tmsv 16-SD and Tmsv 16-SD(%),other P<0.05],however,there was no significantly different between heart transplantation (no rejection) and subjects with normal heart function(all P>0.05).But also average,maximum and minimum value of excursion in three groups was no significantly different (all P>0.05).Conclusions Real-time three-dimensional echocardiography can rapidly and acurately evaluate left and right ventricular function in patients with heart transplantation.
