1 Atrioventricular valve incompetence in 3 patients.

2 Results The right atrioventricular valve can be divided into rough region, transparent region and basin region.

3 Methods: The hearts of 171 Chinese adults were measured valve regions of the right atrioventricular valve.

4 The distension of the coronary sinus will appear as a transverse line (roughly parallel to the atrioventricular valve) in the lower aspect of the left atrium.

5 They can produce a "ball valve" effect by intermittently occluding the atrioventricular valve orifice.

6 The conduction system in the avian heart is specialized and contains a recurrent bundle branch that innervates the right atrioventricular valve.

7 Objective To offer anatomic parameters for diagnosing and treating the diseases about right atrioventricular valve.

8 All cases were confirmed with echocardiography and featured changes including characteristic aortic valve and(or) atrioventricular valve degenerative changes.

9 Methods The hearts of 171 Chinese adults were measured for the forms of the valve regions of the right atrioventricular valve.
