Abstract:
Objective To evaluate the right ventricular(RV)systolic function in patients with primary pulmonary hypertension(PPH)using real -time three -dimensional echocardiography(RT -3DE)and ultrasonic two-dimensional speckle tracking imaging(STI).Methods Patients with PPH were divided into three groups according to pulmonary arterial systolic pressure(PASP),consisted of mild group,moderate group and severe group,with 20 cases in each group.20 healthy cases were included as the control group.The global RV dysfunction,including RV end -diastolic volume(EDV),end -systolic volume(ESV),stroke volume(SV),ejection fraction(EF),tricuspid annular plane systolic excursion(TAPSE),longitudinal peak systolic strain(SL),longitudinal peak systolic strain rate(SRL), longitudinal peak systolic velocity(VL)in RV free wall and interventricular septum for basal,mid and apical segment were detected by using RT -3DE and STI.Results Global RV ESV increased in all groups(t =3.10,7.53,7.72,all P <0.01),but The RV EDV in the moderate and severe group was higher than that of normal and mild groups(t =4.02,5.82,3.04,5.15,all P <0.01),the RT SV and EF in all case groups was fewer than that of normal(t =-9.33 ~-2.71,all P <0.05).Linear correlation analysis showed negative correlation between EF and ESV,EDV (r =-0.776,-0.638,all P <0.01).The level of RV free wall peak systolic displacement of tricuspid annulus, ventricular septal annulus peak systolic displacement,tricuspid annulus peak systolic displacement midpoint and the right longitudinal ventricular shortening fraction were significantly lower than those of the control group(all P <0.01). Linear correlation analysis showed positive correlation between EF and TAPSE(r =0.761,0.593,0.745,0.773,all P <0.01).The VL and SL in RV free wall and interventricular septum for basal,mid and apical segment were fewer than the control group(P <0.05 or P <0.01),but SRL of RV for all segments showed no significantly different in all groups(P >0.05).Conclusion RT -3DE and STI technology can be useful in assessing RV function every period.
