1 to give out leaflets to people -- 散发，发放（传单或广告）
The leaflets are attached to the axis along their entire base.
In such patients, the interventricular defect is usually small, and shunting is limited by tendinous cords tethering the bridging leaflets.
The degree of dysplasia was least in the valves with two leaflets and highest in those with four leaflets.
Both the superior and the inferior bridging leaflets showed partial attachment to the inferior edge of the atrial septum.
The classification is based on the severity of the displacement of the septal and posteroinferior leaflets, with four grades of increasing severity.
There is continuity of the leaflets of the aortic and pulmonary valves because of absence of the outlet septum.
The left junction is dominated by thefibrouscontinuity between one of the leaflets of the mitral valve and those of the aortic valve.
The tricuspid valve had thickening and tethering of its leaflets without downward displacement.
