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.
13 lip 2023 · The distal segment of the right coronary artery continues to curve across the acute cardiac margin in the diaphragmatic atrioventricular groove. At the cardiac crux, the vessel then turns to travel down the interventricular groove and is now referred to as the posterior interventricular or posterior descending artery. It may persist as a ...
1 lis 2009 · The middle cardiac and posterior veins, as well as various atrial veins including the vein of Marshall are other consistent tributaries. In this review, we discuss the gross, developmental radiographic anatomy of the important cardiac venous system to improve understanding amongst interventional electrophysiologists.
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 paź 2024 · Located between the left and right ventricles are two shallower sulci: the anterior interventricular sulcus is visible on the anterior surface of the heart (Figure \(\PageIndex{8.A}\)), whereas the posterior interventricular sulcus is visible on the posterior surface of the heart (Figure \(\PageIndex{8.B}\)).
On the posterior surface of the heart, the right coronary artery gives rise to the posterior interventricular artery, also known as the posterior descending artery. It runs along the posterior portion of the interventricular sulcus toward the apex of the heart, giving rise to branches that supply the interventricular septum and portions of both ...
