摘要:
【摘要】 目的 应用单心动周期实时三维超声心动图(sRT3DE)评价房间隔缺损 (ASD)患者治疗前后右心室收缩功能及其影响因素。方法 选取本院2017年1月~2018年6月收治的45例ASD患者为ASD组,45例健康志愿者为对照组。比较两组二维超声测量右心室舒张末内径(RVd)与右心室面积变化分数(RVFAC),sRT3DE测量右心室舒张末容积(RVEDV)、右心室收缩末容积(RVESV)、右心室每搏量(RVSV)、右心室射血分数(RVEF),比较ASD组封堵术前后及对照组右室收缩功能参数之间的差异,并分析RVEF与ASD大小、RVEDV、RVESV、RVSVASD的相关性,以及RVEF与RVFAC间相关性。结果 RVd、RVEDV、RVESV、RVSV测值比较,ASD术前>ASD术后>对照组,差异有统计学意义(P<001);RVFAC与RVEF测值比较,ASD术前<ASD术后<对照组,差异有统计学意义(P<001)。ASD治疗前RVEF与ASD大小、RVEDV、RVESV呈负相关(r=0439、0310、0688,P<005),与RVSV无相关性(P>005)。RVEF与FAC呈良好正相关(r=0853,P<005)。结论 sRT3DE能准确评价ASD治疗前后右心室收缩功能,ASD右室收缩功能与RVESV具有良好相关性。

Abstract:
【Abstract】 Objective To evaluate the right ventricular systolic function and influencing factors in patients with atrial septal defect (ASD) by single cardiac cycle realtime threedimensional echocardiography (sRT3DE). Methods In 45 cases of ASD and 45 cases of normal control group, we used twodimensional echocardiography to measure right ventricular enddiastolic diameter (RVd) and right ventricular area change scores (RVFAC), and use sRT3DE measure right ventricular enddiastolic volume (RVEDV), at the end of the right ventricular systolic volume (RVESV), right ventricular stroke volume (RVSV), right ventricular ejection fraction (RVEF). We compared the difference of the right ventricular systolic function parameters among ASD preoperation, ASD postoperation and normal control group, and analysis correlation between RVEF and ASD size, RVEDV, RVESV, RVSV,RVFAC respectively. Results ASD preoperation was the largest and control group was the smallest in RVd, RVEDV, RVESV and RVSV with significant differences (P< 001). control group was the largest and ASD preoperation was the smallest in RVFAC and RVEF with significant difference (P< 001). Before ASD treatment, RVEF was negatively correlated with ASD size, RVEDV, RVESV (r=0439,0310,0688, P< 005), and no correlation with RVSV (P>0 005). RVEF was positively correlated with FAC (r=0853, P< 005). Conclusion sRT3DE can accurately evaluate the right ventricular systolic function before and after ASD treatment, and the right ventricular systolic function of ASD has a good correlation with RVESV.
