It extends between the coronary sulcus, and the apex of the heart; [1] upon reaching the diaphragmatic surface of the heart, it ends at the notch of cardiac apex. [3] It contains the anterior interventricular branch of the left coronary artery, and great cardiac vein. [1] [2]
The great cardiac vein (left coronary vein) is a vein of the heart.It begins at the apex of the heart and ascends along the anterior interventricular sulcus [1] before joining the oblique vein of the left atrium to form the coronary sinus [2] upon the posterior surface of the heart.
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 ...
The anterior interventricular sulcus and posterior interventricular sulcus extend from the base of the ventricular portion to a notch, the notch of cardiac apex, (or incisura apicis cordis) on the acute margin of the heart just to the right of the apex.
The interventricular 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. The lower part of the septum, which is the major part, is thick and muscular, and its much smaller upper part is thin and membraneous.
Interventricular groove may refer to: Anterior interventricular sulcus , one of two grooves that separates the ventricles of the heart, near the left margin Posterior interventricular sulcus , one of the two grooves that separates the ventricles of the heart, near the right margin
At the superior end, the ligamentum attaches to the aorta—at the final part of the aortic arch (the isthmus of aorta) or the first part of the descending aorta. [2] On the other, inferior end, the ligamentum is attached to the top of the left pulmonary artery.
The coronary sinus runs transversely in the left atrioventricular groove (coronary sulcus) on the posterior aspect of the heart. [5] The sinus, before entering the right atrium, is considerably dilated - nearly to the size of the end of the little finger.
