超声心动图对房间隔缺损介入治疗后随诊观察

目的：评价超声心动图对继发孔型房间隔缺损（ASD）介入治疗的近期及远期疗效。方法：继发孔型ASD患者778例，男276例，女502例；男：女=1：1．8，年龄2-74岁，平均（29．6±9．6）岁；其中中央型765例，多发孔型13例，合并畸形91例。使用仪器：东芝6000型，Philips IE33彩色超声诊断仪（TIE）及1500型食道超声心动图（TEE）。探头频率分别为2．5MHz和5MHz。介入术后复查TTE，主要记录各心腔内径，包括右室流出道（RVOT）及右室内径（RV）。观察闭合器的位置、有无残余分流、瓣膜反流及心包积液和心功能状态。出院后1个月、3个月、半年及1年，TTE随诊。TTE选择切面为心尖四腔心及胸骨旁四腔心，剑突下四腔心及两房心切面，大动脉短轴及剑突下短轴切面。结果：超声检出介入手术并发症发生率2．3％。其中闭合器脱落5例，脑梗死2例，心包积液5例，残余分流4例，肺动静脉瘘1例。结论：超声对ASD介入治疗近期和远期疗效的判定有临床意义。

Follow-up study of echocardiography afar interventional therapy of atrial septal defects

Objective： To assess the follow-up outcome of echocardiography in patients who had interventional therapy of atrial septal defects （ASD）. Methods： Of the 778 patients with ASD secundum, 276 were men and 502 women, male：female is 1：1.8, age ranged from 2 to 74 years old, mean age （29.6±9.6）years old. All of the 778 ASD patients, 765 patients had central type and single ASD, 13 patients had multiple ASD. In addition, 91 patients accompanied with other malformations. Toshiba Type 6000, Philips IE33 color Doppler ultrasonography and Type 1500 esophagus color Doppler ultrasonography were used. The frequency of detecting probe was 2.5MHz and 5MHz. All the patients after interventional therapy were checked by rITE and inner diameters of the heart chamber were recorded, especially the inner diameter of RVOT and RV. In addition, the closer＇s position, residual shunt, valvular regurgitation and cardiac status were observed. Follow-up evaluation was performed in 778 patients by TTE at 1, 3, 6 and 12 months after discharged. The section of TIE was apex cordis and parasternal 4-chamber plane, subappendix 4-chamber and 2-atrium plane, main artery and subappendix short-axis plane. Results： The incidence rate of interventional operation＇s complication was 2.3%, including 5 patients had closer shedding, 2 patients had brain infarction, 5 patients had pericardial effusion, 4 patients had residual shunt and 1 patient had pulmonary arteriovenous fistula. Conclusion： TIE had clinical value in follow-up examination for patients who had ASD interventional therapy.
