  2. Coronary sulcus - Wikipedia

    en.wikipedia.org/wiki/Coronary_sulcus

    The coronary sulcus (also called coronary groove, auriculoventricular groove, atrioventricular groove, AV groove) is a groove on the surface of the heart at the base of right auricle that separates the atria from the ventricles.

  3. Anterior interventricular sulcus - Wikipedia

    en.wikipedia.org/wiki/Anterior_interventricular...

    The anterior interventricular sulcus (or anterior longitudinal sulcus) is one of two grooves separating the ventricles of the heart (the other being the posterior interventricular sulcus). They can also be known as paraconal interventricular groove or subsinosal interventricular groove respectively.

  4. Crux cordis - Wikipedia

    en.wikipedia.org/wiki/Crux_cordis

    The crux cordis or crux of the heart (from Latin "crux" meaning "cross") is the area on the lower back side of the heart where the coronary sulcus (the groove separating the atria from the ventricles) and the posterior interventricular sulcus (the groove separating the left from the right ventricle) meet.

  5. Posterior interventricular sulcus - Wikipedia

    en.wikipedia.org/wiki/Posterior_interventricular...

    The posterior interventricular sulcus or posterior longitudinal sulcus is one of the two grooves separating the ventricles of the heart (the other being the anterior interventricular sulcus). They can be known as subsinosal interventricular groove or paraconal interventricular groove respectively.

  8. Posterior descending artery - Wikipedia

    en.wikipedia.org/wiki/Posterior_descending_artery

    In the coronary circulation, the posterior descending artery (PDA), also called the posterior interventricular artery (PIV, PIA, or PIVA), is an artery running in the posterior interventricular sulcus to the apex of the heart where it meets with the left anterior descending artery also known as the anterior interventricular artery.

    Proximal: starting at RCA origin, spanning half the distance to the acute margin [6] [7]; Middle: from proximal segment to the acute margin [6] [7]; Distal: from middle segment to origination point of the posterior interventricular artery, where the posterior interventricular sulcus meets the atrioventricular groove on the base of the heart.
