In 5 cases with multiple ASD, 4 cases implanted only one occluder to close multiple ASD holes. Another case, in which the distance between each ASD holes were 9 mm, was closed by implanting two occluders (20 mm, 16 mm occluder, respectively).

• 5例多孔ASD,有4例置入1个封堵器直接封堵多个缺损孔,1例(两个缺损孔之间距离为9mm)分别用20mm和16mm两个封堵器封堵。
