Ultrasonic examination showed that the central part of aortic valve without coronal valve showed strong echo of crest, the local thickening of valve lobe, the enhancement of echo, the attachment point was not clear, and the leaves on both sides of crest like strong echo were not separated when opening. "O" sign appeared at the opening of the valve (fig. 1A), and "X" sign at the opening of the valve when it was closed.
