【摘要】：目的:探讨三维超声心动图(RT-3DE)在评价房间隔缺损(ASD)封堵术后右心房功能变化的价值。方法:纳入继发孔型ASD患者50例为ASD组,30例体检正常者为正常对照组。ASD组的所有患者均成功接受介入封堵术,并分别在术前、术后3天、1个月、3个月接受RT-3DE检查。测量右心房功能相关指标:右心房收缩前容积(Vpre)、右心房最小容积(Vmin)、右心房最大容积(Vmax)、右心房总排空容积(Vt)、右心房总排空容积分数(Ft)、主动排空容积分数(Fa)、被动排空容积分数(Fp)。结果:封堵术前,ASD组患者的Vmax、Vmin、Vpre、Vt、Fa均明显高于正常组(P0.05),而Ft、Fp均低于正常组(P0.05);ASD组患者术后第3天Vmax、Vmin、Vpre、Vt均高于正常组(P0.05),而Ft、Fp、Fa均低于正常组(P0.05);ASD组患者封堵术后第3天、1个月、3个月的Vmax、Vmin、Vpre、Vt、Fa均明显低于术前(P0.05),Ft、Fp均高于术前(P0.05);ASD组患者术后第3个月时的Vmax、Vmin、Vpre、Vt、Fa、Ft、Fp与正常组比较,差异均无统计学意义(P0.05)。结论:RT-3DE显示ASD患者右心房容积及功能存在异常,封堵术后,右心房容积及功能在短期内即得到改善,但与正常右心房尚有差异;3个月后,基本恢复至正常水平。RT-3DE对评价ASD封堵术后右房容积及功能的变化有重要价值。
[Abstract]:Objective: to evaluate the value of three dimensional echocardiography RT-3DEE in evaluating the changes of right atrial function after ASD closure. Methods: fifty patients with secondary perforated ASD were included in the ASD group and 30 normal controls. All patients were successfully treated with interventional closure. And before the operation, RT-3DE was performed 3 days, 1 month and 3 months after operation. The relative indexes of right atrial function were measured as follows: right atrial presystolic volume, right atrial minimum volume, right atrium maximal volume, right atrial total emptying volume, right atrial total emptying volume, right atrial total emptying volume, right atrial total emptying volume, right atrial total ejection volume, right atrial presystolic volume, right atrial minimum volume, right atrial maximal volume, right atrial total emptying volume and right atrial total emptying volume. Results: the Vmax Vmin VpreV Fa of ASD group before closure was significantly higher than that of normal group (P 0.05), while FtFP was lower than that of normal group 3 days after operation (P 0.05), and the Vmax Vmin Vmin VpreVT in ASD group was significantly higher than that in normal group 3 days after operation (P 0.05), while FtFpFa Fa Fa Fa was significantly higher in ASD group than that in normal group 3 days after operation. All the patients in the ASD group were lower than those in the normal group on the 3rd day, the first month and the third month after the closure, and the VmaxV minn VpreVt Fa was significantly lower than that in the preoperation P0.05 FtFtFp, which was higher than that in the preoperation P0.05 + ASD group at the 3rd month after the operation, and the VmaxVminn VpreVpreVtTU FtFtFP was significantly higher than that in the normal group at the 3rd month after the operation, compared with the normal group. Conclusion: the volume and function of right atrium in ASD patients were abnormal. After occlusion, the volume and function of right atrium were improved in a short period of time, but still different from those of normal right atrium. Basically returning to normal level. RT-3DE has important value in evaluating the changes of right atrial volume and function after ASD closure.
