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.
They can be known as subsinosal interventricular groove or paraconal interventricular groove respectively. It is located on the diaphragmatic surface of the heart [1] [2] near the right margin. [2] It extends between the coronary sulcus and the (notch of [2]) apex of the heart. It contains the posterior interventricular artery and middle ...
Interventricular sulcus may refer to: Posterior interventricular sulcus, one of the two grooves that separates the ventricles of the heart, near the right margin;
It follows the anterior interventricular sulcus around the pulmonary trunk. Along the way it gives rise to numerous smaller branches that interconnect with the branches of the posterior interventricular artery, forming anastomoses. An anastomosis is an area where vessels unite to form interconnections that normally allow blood to circulate to a ...
The two sulci meet in the 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.

The interventricular septum is the stout wall separating the ventricles, the lower chambers of the heart, from one another. The ventricular septum is directed obliquely backward to the right and curved with the convexity toward the right ventricle; its margins correspond with the anterior and posterior interventricular sulci.
Widow maker is an alternative name for the anterior interventricular branch of the left coronary artery. [9] [3] The name widow maker may also apply to the left coronary artery [10] or severe occlusions to that artery. [11] [12] This term is used because the left main coronary and/or the left anterior descending supply blood to large areas of ...
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.
