Abstract： 目的经导管置入CardioSEAL封堵器治疗二孔型房间隔缺损(ASD),并对其疗效进行初步评价.方法共12例,术前行经食管超声心动图(TEE)检查,示11例为单一二孔型ASD,1例为多发性ASD;ASD平均直径为(13.14±3.48)mm(8～20 mm).所有病例均在透视及TEE监视下经导管置入CardioSEAL封堵器封堵ASD,术后24h、1个月、3个月及1年分别行经胸超声心动图(TTE)、心电图(ECG)及X线检查评价疗效.结果 11例封堵器置入获得成功.封堵器置入成功者术后即刻TEE,显示3例存在少量残余分流;术后1个月TTE显示仅1例存在少量残余分流,1例存在二尖瓣少量返流,但未见左房、室增大.术后3个月及1年随访,除上述1例仍存在残余分流外,其余10例ASD完全闭合者未见封堵器移位及ASD再通.结论经导管置入CardioSEAL封堵器治疗ASD是一种有效的非手术方法,操作简便,技术成功率高,近、中期疗效可靠,尤其适合于某些特殊解剖类型ASD的介入治疗,其临床应用的中、远期疗效尚需继续观察.
