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.
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. [1]
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. It is located on the diaphragmatic surface of ...
Interventricular groove may refer to: . Anterior interventricular sulcus, one of two grooves that separates the ventricles of the heart, near the left margin; Posterior interventricular sulcus, one of the two grooves that separates the ventricles of the heart, near the right margin
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.
In relation to the rib cage, the coronary sulcus spans from the medial side of the 3rd left costal cartilage, to the middle of the right 6th costal cartilage. [1] Epicardial fat tends to be concentrated along the coronary sulcus. [4] [5] There are two coronary sulci in the heart, including left and right coronary sulci.
Interventricular sulcus may refer to: Posterior interventricular sulcus , one of the two grooves that separates the ventricles of the heart, near the right margin Anterior interventricular sulcus , one of two grooves that separates the ventricles of the heart, never the left margin
