Great cardiac vein

(Science: anatomy, vein) Begins at the apex of the heart (where it anastomoses with the middle cardiac vein), runs first with the anterior interventricular artery as it ascends the anterior interventricular groove, then turns to the left as it approaches or reaches the coronary groove to run with the circumflex branch of the left coronary artery; it merges with the oblique vein of the left atrium to form the coronary sinus.

Synonym: vena cordis magna, left coronary vein, vena cardiaca magna.
