我国每年有15万各种类型先天性心脏病的新生儿出生,房间隔缺损(ASD)在先天性心脏病中发病率居首位,其中继发孔型约占总数的95％,而中央型又占继发孔型的76％。既往手术是其治疗的唯一方法、但存在创伤大、疤痕形成和手术意外等情况。经导管封堵房间隔缺损,无需体外循环,手术时间短,痛苦小,康复快,术后处理简单。超声心动图在ASD经心导管封堵治疗中起着极为重要的作用,尤其术前对病例的正确选择和
Every year, 150,000 newborns of various types of congenital heart disease are born in our country. The incidence of atrial septal defect (ASD) is the highest in congenital heart disease, of which the secondary type accounts for about 95% of the total, while the central type Again accounted for 76% of the pass-type. Previous surgery is the only method of treatment, but there are trauma, scar formation and surgical accidents and so on. Transcatheter closure of atrial septal defect, without extracorporeal circulation, short operative time, pain, quick recovery, postoperative treatment is simple. Echocardiography plays a very important role in the ASD transthoracic closure, especially in the preoperative choice of cases and
