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.
20 kwi 2023 · Posterior interventricular sulcus – located on the posterior surface of the heart and represents the separation of the left and right ventricle. It contains the posterior interventricular artery and the middle cardiac vein.
18 sty 2024 · The posterior interventricular artery (posterior descending artery, PDA) is a branch of the right coronary artery. It is also commonly referred to as the inferior interventricular artery, a more accurate name given that it is not located on the posterior surface of the heart.
30 paź 2023 · The coronary sinus is located in the posterior portion of the coronary sulcus on the diaphragmatic (inferior) surface of the heart. The sinus serves as the primary collector of cardiac venous blood. Along with the posterior interventricular sulcus, the coronary sulcus makes the crux of the heart or crux cordis.
24 lip 2023 · The posterior interventricular artery runs alongside the middle cardiac vein down the posterior interventricular sulcus and supplies the AV node, the posterior 1/3 of the interventricular septum, the posterior 2/3 walls of the ventricles, and is the only vessel supplying the posteromedial papillary muscle.
17 sty 2024 · A groove that runs lengthwise along the heart, from the base to the apex, divides the right and left ventricles—this is called the interventricular groove, or sulcus. A groove that runs around the base of the heart divides the atria from the ventricles—this is called the atrioventricular groove.
7 lip 2010 · Unlike the anterior interventricular sulcus, its vascularization can demonstrate vast variability since it can be irrigated by branches of all three major arteries (RCA, LCX and LAD). The posterior interventricular artery travels in the PIS.
