Abstract:
Objective To investigate the alternation of right ventricular volume and systolic function in patients with severe pulmonary regurgitation under percutaneous pulmonary valve implantation(PPVI) by real-time three-dimensional echocardiography(RT-3DE).Methods Ten patients with severe pulmonary regurgitation were enrolled.The 2D echocardiography images and real-time 3D full volume images on apical four-chamber view on a Philips IE33 system were acquired before PPVI and at 3 days,1 month,3months and 6 months after PPVI.Right ventricular end diastolic volume (EDV),end systolic volume(ESV),stroke volume (SV),ejection fraction(EF),fractional area change(FAC),tricuspid annular plane systolic excursion (TAPSE),right ventricular longitudinal strain-free wall(RVLSf) and right ventricular longitudinal strainseptum(RVLSs) were analysed using off-line TomTec software,the differences among the five groups were compared,and correlation analysis was made between the CMR and RT-3DE measurements.Results The level of pulmonary regurgitation had decreased or disappeared after PPVI.Compared with the preoperation,EDV,ESV at 3 days,1 month,3months and 6 months after operation had decreased significantly.EF,FAC,TAPSE,RVLS had increased significantly(all P ＜0.05).There were close correlation in EDV,ESV,EF between RT-3DE and CMR(pre-operation r =0.811,0.817,0.807,post-operation r =0.735,0.834,0.800,all P ＜0.055).Conclusions RV volume notably decreases while RV systolic function remarkably improves.The RT-3DE is a helpful technology in the evaluation of right ventricular volume and systolic function in patients after PPVI.
