Location:
defined by the following structures within the right atrium: (1) The ostium of the coronary sinus, posteriorly; (2) the anterior-septal leaflet commissure; and (3) the tendon of Todaro (a tendinous structure connecting the valve of the inferior vena cava ostium to the central fibrous body), posteriorly.

Importance in cardiovascular diseases:
used as an anatomical landmark for location of the atrioventricular node during electrophysiology procedures such as pacing or ablation.
