right ڈرنری ڈری now let's take a look at the left ڈرنری ڈری again let's go back to the beginning this is the interior of the aortic opening this is the left ڈرنری ڈرنری ڈرنری and there's an osteum there and arising from that osteum is the left main ڈرنری ڈری انشانی the left main ڈرنری ڈری also runs in the left part of the ڈری ڈرنری ڈرنری ڈرنری ڈرنری and it is in undercover of the left ڈرنری for a short distance and immediately thereafter it divides into two main branches this is one brain branch this is known as the anterior ڈرنری ڈرنری ڈرنری and the other main branch is this one this is the circumflex ڈرنری so let's take them one by one the anterior ڈرنری ڈرنری ڈرنری it's also referred to as the left anterior descending artery ڈرنری ڈرنری ڈرنری in clinical parlance this runs in the anterior part of the inter ventricular group and this is a major supply of the left ventricle and it also supplies part of the right ventricle it supplies the anterior two thirds of the inter ventricular septum and it also supplies the av bundle of his and it also supplies the right and the left bundles the conduction system and then it makes a curve just adjacent to the apex of the heart and it goes and it starts traveling up in the posterior ڈرنری ڈرنری ڈرنری and it stops short of the posterior descending artery but it is not anastomals anterior descending artery as it is descending down it gives rise to a number of branches which run diagonally like this in this case we can see only one branch this is referred to as the diagonal branch in other cases there'll be more than one in which case we refer refer to them as diagonal one d1 d2 etc this also supplies the left ventricle and if you notice the course of the anterior inter ventricular artery or the left anterior descending artery you notice that it is tortures this is a very common feature of arteries anyway in the human body where there is movement of the structures and in this case because the ventricular wall is in موشنہ all the time tortuosity is essential now let's take a look at the other branch this is the circumflex artery the circumflex artery it also runs in the anterior part of the coronary groove and then it winds around that is the reason why it's got circumflex and it goes runs in the posterior part of the a coronary groove and then it supplies the bulk of the left ventricle in this position we can see the branches which are going to the left ventricle it also gives a branch to the ab bundle of his so therefore the ab bundle of his receives branch from the posterior descending artery anterior descending artery as well as from the circumflex artery now this circumflex artery in an ideal situation gives rise to a branch which runs on the left margin of the heart but in this case we notice that the left marginal artery is arising separately it is not arising from the circumflex and we can see that there are two one of them is arising from here from the lad and the other one is also arising from the near the lad at its bifurcation into the circumflex and these are the left marginal artery and these are the ones which are supplying the left margin of the heart which is formed mostly by the left ventricle coming back to the left marginal artery which we have noticed in this case is dividing into two branches here and here and it's also supplying separately part of the left ventricle this is also in clinical parlance refer to as the obtuse marginal and again depending on the number of them they are referred to as om1 om2 so in this case we can see that there is one om1 om2 and om3 so again to summarize the distribution of the left coronary artery the left coronary artery supplies the left atrium most of the left ventricle it supplies the anterior two-thirds of the interventricular septum it supplies the ab bundle it supplies the right and the left bundles and it also supplies the region of the apex of the heart now let's come quickly to the venous drainage we will remember free principal veins we'll start from the anti-interventricular groove it is not visible here but running with the lad left anterior descending artery there'll be a vein running up here and that is known as the anterior intraventricular vein this vein as it runs up it reaches the coronary groove and then it becomes known as and we can see part of it here because known as the great cardiac vein and we can see part of the great cardiac vein here gcv this great cardiac vein it runs with the circumflex artery and this other part of the great cardiac vein now here there's an important anatomical fact the great cardiac vein and the circumflex both of them run in the coronary groove but one is a vein other is an artery and the blood flow in both of them are in the same direction which is a unique situation in the human body here the great cardiac vein then continues to run in the posterior part of the coronary groove and then in the posterior part of the coronary groove it receives a vein from the left atrium which is not visible here because it was very small and frable and that is known as the oblique vein of left atrium which is a remnant of the left superior venaqeva and once that left oblique vein of left atrium opens into the great cardiac vein in this region then the rest of it becomes known as the coronary sinus and this is the largest venus drainage of the heart and we have lifted up the coronary sinus here and now let's take a look at the tributaries which open into the great cardiac vein and coronary sinus collectively so let's start from the left margin of the heart we can see this tributary which accompanies the left marginal artery which i mentioned earlier this is the left marginal vein so this is the left marginal vein which opens into the great cardiac vein the oblique vein of left atrium i have already mentioned then we have this vein this is draining on the posterior surface of the left ventricle this is the left posterior ventricular vein and this is also opening into the coronary sinus then we have this vein running in the posterior intraventricular groove along with the posterior descending artery and this is referred to as the middle cardiac vein and finally we have this vein here which opens into the coronary sinus near its termination this is the small cardiac vein the other end of the small cardiac vein a remnant of that is visible here i have cannulated the coronary sinus in the posterior coronary groove and we can see that the other end of the probe has come into the right atrium so this is the opening of the coronary sinus the coronary sinus opens into the right atrium just behind the fassovelis very close to the inter arterial septum and in this region if you see closely you see some filamentous structures those are the remnants of the valves of the coronary sinus and it is also referred to as the thebisian valve and additionally we incidentally we can also see remnant of the valve in around the opening of the inferior vena keva okay so this is the opening and in the region of the opening of the coronary sinus is the location of the atrium ventricular node so this is the complete venus drainage and just to complete the story there are numerous other veins small veins which are not visible here which are referred to as the anterior cardiac veins and the venae cordus minimae which open mostly into the right atrium directly so this is the venus drainage and the arterial drainage of the heart thank you very much for watching dr sanjayas signing out if you have any
