11 godz. temu · The primary function of the middle cardiac vein is to drain deoxygenated blood from the posterior portions of the left and right ventricles. The posterior interventricular groove, where the middle cardiac vein is located, corresponds to the myocardial tissues of both ventricles, particularly the areas involved in pumping blood through the heart.
18 sty 2024 · Its main function is to supply the diaphragmatic (inferior) surface of the myocardium and interventricular sulcus of the heart. The inferior interventricular artery can arise from either the left or right coronary artery.
1 lis 2009 · The operator typically uses counterclockwise torque to cannulate the CS. Once the CS has been cannulated, clockwise torque needs to be applied to turn the sheath or guiding catheter towards a ventricular vein. Often the posterior vein will be cannulated in this rotation and can be used.
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.
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.
The posterior interventricular vein is also known as the inferior interventricular vein and the middle cardiac vein. The posterior interventricular vein arises at the left ventricular apex and travels in the posterior interventricular groove with the posterior descending artery and drains into the coronary sinus . 11 It drains a portion of the ...
