摘　　要：目的探讨合并重度肺动脉高压的房间隔缺损(ASD)介入封堵治疗的可行性。方法应用经胸超声心动图(TTE)术中实时监测,对12例合并重度肺动脉高压的ASD进行介入试封堵,其中男性4例,女性8例,年龄46～75岁(56±5岁),比较手术前后右室舒张末期前后径、右心系统血流动力学指标及肺动脉收缩压的变化。结果 12例合并重度肺动脉高压的房间隔缺损均成功封堵,术后右室舒张末期前后径、右心血流动力学指标及肺动脉收缩压均有明显改变(P<0.05)。结论对于合并重度肺动脉高压的继发孔房间隔缺损,应该采取积极的治疗手段。超声心动图贯穿了介入封堵治疗的全过程,为封堵治疗的成功提供了重要的保障。Objective To evaluate the efficacy and safety of closure atria septal defect（ASD） in the patients with severe pulmonary hypertension（SPH） by using transthoracic echocardiographraphy（TTE）.Methods 12 cases of ASD associated with SPH were selected to attend this trial.They were occluded by using transcatheter occluder.The right ventricular late-diastolic diameter（RVLDD）,tricuspid valve early-diastolic peak velocity（TVEDV）,pulmonary valve systolic peak velocity（PVSPV） and pulmonary artery systolic pressure（PASP） were studied dynamically by TEE in various periods of the whole operation.Results All cases were successful.The RVLDD,TVEDV,PVSPV and PASP decreased significantly than before（P0.05）.Conclusion ASD associated with SPH should be treated by active ways.Transthoracic echocardiography played an important role in successful operation and evaluating the short-term and long-term therapeutic effectiveness.
