| 目的 基于二维斑点追踪成像(2D-STI)及实时三维超声心动图(RT-3DE)观察退行性二尖瓣反流(DMR)与功能性二尖瓣反流(FMR)患者右心功能。方法 前瞻性选取30例DMR(DMR组)、30例FMR(FMR组)及30名健康受试者(对照组),比较3组间及组间两两常规超声参数、右心室2D-STI及RT-3DE参数。结果 3组间三尖瓣瓣环位移(TAPSE)、面积变化分数(FAC)、肺动脉收缩压(PASP)、右心室收缩末期容积(RVESV)、右心室每搏输出量(RVSV)、右心室射血分数(RVEF)、左心室射血分数(LVEF)及三尖瓣有效反流口面积(TR-EROA)差异均有统计学意义(P均＜0.05)。相比对照组,DMR组及FMR组TAPSE减低、PASP升高(P均＜0.05),DMR组与FMR组TAPSE、FAC、PASP、RVESV、RVSV、RVEF、LVEF及TR-EROA差异有统计学意义(P均＜0.05)。3组间右心室整体纵向应变(RVGLS)、右心室游离壁纵向应变(RVFWLS)、右心室游离壁3个节段各纵向应变及右心室肺动脉(RVPA)耦联参数差异,以及两两组间比较差异均有统计学意义(P均＜0.05)。3组间RT-3DE-RVESV、RT-3DE-RVSV及RT-3DE-RVEF差异,且FMR组其他2组差异均有统计学意义(P均＜0.05)。结论 相比DMR,FMR患者右心功能改变更显著。 |

| 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. |
