【摘要】：目的评价实时三维经食管超声心动图(RT-3DTEE)在临床治疗特殊类型房间隔缺损(ASD)风险评估中的应用价值。方法对57例特殊类型ASD患者分别通过二维经胸超声心动图(2DTTE)、二维经食管超声心动图(2DTEE)及RT-3DTEE进行术前评估。观察ASD相关声像图表现,并对比三者对临床治疗的指导作用。结果 57例特殊类型ASD中,采用2DTTE及2DTEE对46例可清晰显示ASD的形态和数目,对其余11例仅能诊断ASD为不规则或两孔可能,而RT-3DTEE对57例均可直观显示ASD形态和数目。采用2DTTE、2DTEE及RT-3DTEE测量收缩末期左心房横径(LATD)、右心房横径(RATD)、右心室舒张末期内径(RVDD)、左心室舒张末期内径(LVDD)差异均无统计学意义(P均0.05);测量ASD的最大径(ASDD)时,2DTEE与2DTTE、RT-3DTEE与2DTTE差异均有统计学意义(P均0.05)。3种方法测量ASD上腔静脉侧、主动脉侧及心房顶侧的残边长度总体差异均无统计学意义(P均0.05);3种方法测量ASD下腔静脉侧残边长度总体差异有统计学意义(F=50.39,P0.001),两两比较差异均有统计学意义(P均0.05)。通过RT-3DTEE对57例均可指导ASD治疗方式,而2DTTE对5例不能确定,2DTEE对2例不能确定。结论 RT-3DTEE可提供丰富的影像诊断信息,对特殊类型ASD治疗的风险评估具有重要指导意义。
[Abstract]:Objective to evaluate the value of real-time three-dimensional transesophageal echocardiography RT-3DTEE in the risk assessment of special type atrial septal defect (ASD). 2DTEE) and RT-3DTEE were evaluated before operation. The findings of ASD associated sonogram were observed. Results in 57 cases of special type ASD, the morphology and number of ASD could be clearly displayed by 2DTTE and 2DTEE, while the other 11 cases could only be diagnosed as irregular or two holes. However, RT-3DTEE could visualize the morphology and number of ASD in 57 cases. There was no significant difference in the measurement of left atrial transverse diameter (LATDV), right atrial transverse diameter (Rad), right ventricular end-diastolic diameter (RVD) and left ventricular end-diastolic diameter (LVDDD) by 2DTTET 2DTEE and RT-3DTEE. There were significant differences in 2DTEE and 2DTTERT-3DTEE between 2DTTEE and 2DTTE in measuring the maximum diameter of ASD. There were significant differences between 2DTEE and 2DTTERT-3DTEE and 2DTTE. There was no significant difference in the length of the residual edge between the aortic side and the roof side of the atrium. There were significant differences in the length of the residual edge of the inferior vena cava between the three methods of measuring the length of the remnant edge of the inferior vena cava in ASD (P < 0.05). There were significant differences in the length of the residual edge between the two sides (P < 0.05). 57 cases of ASD were treated by RT-3DTEE. 2DTTE can not be confirmed in 5 cases and 2DTEE in 2 cases. Conclusion RT-3DTEE can provide abundant imaging diagnostic information and has important guiding significance for the risk assessment of special type of ASD therapy.
