Anatomical observation of the region and forms of right atrioventricular valves of Chinese adults' hearts

Objective To offer anatomic parameters for diagnosing and treating the diseases about right atrioventricular valve.Methods The hearts of 171 Chinese adults were measured for the forms of the valve regions of the right atrioventricular valve.Results The right atrioventricular valve can be divided into rough region,transparent region and basin region.The types of the valve are triangle,semi-ellipse,half of the circular shape,rectangle and trapezium.The height of the double anterior valve is the highest,while the septalis valve is the lowest.As the chordae tendineae of the anterior valve's transparent region and basin region of ventricle is the least,it's the most flexible of the right atrioventricular valve.Contrary,the chordae tendineae of the septalis valve and the posterior-septalis valve of ventricle is more,shorter and smaller and therefore it's the least flexible,which is easier to stick to the interventricular septum when diseases happen.Conclusion More attention should be paid attention to the anatomical traits of valves during operation.
