采用经食管三维超声心动图对房间隔进行形态学观察.结果显示:正常人的房间隔结构连续完整,房间隔缺损者能观察并确定缺损的位置、大小、形态与类型;房间隔膨胀瘤者可见房间隔似一“袋”状结构,突向右房.认为:三维重建后的房间隔显示清晰、直观、立体感强,有助于对房间隔缺损的空间、位置等的精确判断,能为心外科医生在术前提供可靠的信息. Atrial septum was observed by transesophageal echocardiography. The results showed that the atrial septum of normal people was continuous and intact, the location, size, shape and type of defect were observed and confirmed by atrial septal defect. Can be seen atrial septum resembles a “bag” -like structure, protruding to the right room that: three-dimensional reconstruction of the atrial septum display clear, intuitive, strong three-dimensional, contribute to the atrial septal defect space, the location of accurate judgments, Provide reliable information for cardiac surgeons before surgery.
