Coronary vessel anatomy. The anatomy of the veins of the heart is very variable but generally it is formed by the following veins. Circumflex cx the cx lies in the left av groove between the left atrium and left. There are two coronary arteries the right coronary artery and the left coronary artery which emerge from the ascending aort from the right and left aortic sinuses respectively.

Coronary arterial dominance is defined by the vessel which gives rise to the posterior descending artery pda which supplies the myocardium of the inferior 13 rd of the interventricular septum. There are two coronary arteries the right coronary artery rca and left coronary artery lca which originate from their respective sinuses of valsalvathe rca from the right sinus of valsalva and the lca from the left sinus of valsalva. Left anterior descending lad the lad travels in the anterior interventricular groove.

The right sinus of valsalva is located anteriorly and the left sinus of valsalva posteriorly and to the left. Coronary arteries are named as such due to the way they encircle the heart much like a crown. The right coronary artery rca originates in the right sinus of valsalva and runs in the right ventricular side of the atrioventricular groove.

The main coronary arteries may be considered to be located in two planes. The left main coronary artery supplies blood to the left side of the heart muscle the left ventricle and left atrium. Most hearts 80 85 are right dominant where the pda is supplied by the rca.

The coronary circulation refers to the vessels that supply and drain the heart. Normal coronary artery anatomy. Most of the blood of the coronary veins returns through the coronary sinus.

The coronary arteries originate as the right and left main coronary arteries which exit the ascending aorta just above the aortic valve coronary ostia. The coronary artery giving off the posterior interventricular. Left main coronary artery lmca.
