Koch triangle
The Koch triangle is the area of the right atrium of the heart in which the atrioventricular node (AV node) is located.
Form the boundaries of this zone
- the confluence of the coronary sinus ( Ostium sinus coronarii )
- the edge of the ventricular septum-side tricuspid ( cuspis septalis ) and
- the Todaro tendon (an extension of the valve of the confluence of the inferior vena cava into the right atrium ( Valvula venae cavae inferioris ) in the direction of the cardiac skeleton ).
