RBC size disparity and the presence of spherocytes (12%, Figure 1). RBC osmotic fragility was increased (hemolysis began at 0.55% NaCl and was complete at 0.50% NaCl).

Transcatheter closure of ASD shown by transthoracic color Doppler echocardiography. The apical four-chamber section showed (A) left to right shunt at the level of atrial septum, (B) the continuous interruption of the atrial septum with a loss of about 14 mm, and (C) the atrial septal occluder was well-positioned without residual shunt (see arrow). (D) X-ray examination of left anterior oblique position after interventional closure showed that the occluder was fixed and the shape was normal (see arrow).

Echocardiography showed that the diameter of ASD was 14 x 10 mm (Figures 2A,B). The whole process of cardiac catheterization was smooth, and a 16-mm ASD occluder was placed through 8F delivery sheath (Figures 2C,D).
