Abstract:
Objective To observe right heart function in degenerative mitral regurgitation(DMR)and functional mitral regurgitation(FMR)patients based on two-dimensional speckle tracking imaging(2D-STI)and real-time three dimensional echocardiography(RT-3DE).Methods Thirty cases of DMR(DMR group),30 cases of(FMR group)and 30 healthy subjects(control group)were prospectively enrolled.Routine ultrasound parameters,right ventricular 2D-STI and RT-3DE parameters were compared among 3 groups and between each 2 groups.Results Significant differences of tricuspid annular plane systolic excursion(TAPSE),fractional area change(FAC),pulmonary artery systolic pressure(PASP),right ventricular end systolic volume(RVESV),right ventricular stroke volume(RVSV),right ventricular ejection fraction(RVEF),left ventricular ejection fraction(LVEF)and tricuspid regurgitation effective regurgitant orifice area(TR-EROA)were found among 3 groups(all P＜0.05).Compared with control group,TAPSE decreased but PASP increased in DMR and FMR groups(all P＜0.05),and significant differences of TAPSE,FAC,PASP,RVESV,RVSV,RVEF,LVEF and TR-EROA were noticed between DMR group and FMR group(all P＜0.05).Significant differences of right ventricular global longitudinal strain(RVGLS),right ventricular free wall longitudinal strain(RVFWLS),longitudinal strain of 3 segments of right ventricular free wall,as well as of right ventricular pulmonary artery(RVPA)coupling parameters were found among 3 groups and between each 2 groups(all P＜0.05).Significant differences of RT-3DE-RVESV,RT-3DE-RVSV and RT-3DE-RVEF were found among 3 groups(all P＜0.05)and between FMR group and the other 2 groups(all P＜0.05).Conclusion Compared with DMR,right heart function changed more significantly in FMR patients.
