خامل و بیدشتشنے میں سکتا ہوں گا now let us take a look at the full course of the right corner Aadri and then we shall mention the branches and the full distribution the right corner Aadri initially it runs in the right anterior atribentricular groove or the right anterior cornering groove it is partially hidden under the right oracle for a short distance and then it comes this was all covered by fat which we have removed and then it goes to the back now it is in the posterior coronary groove and here it is known as rpca in right posterior coronary artery then when it reaches the crux of the heart the crux of the heart is the junction between the posterior interventricular groove and the posterior coronary groove when it reaches the crux of the heart it makes an almost 90 degrees bend and then now it is known as the posterior descending artery and here it terminates in the posterior interventricular groove without anastomousing with the anterior interventricular artery which i shall mention a little later if you take a close look you find that the posterior descending artery is quite tortuous here this tortuosity is a feature of the main coronary arteries because the heart is in constant motion and this tortuosity compensates for the mobility of the heart so this is the full course of the coronary artery the main coronary artery right posterior coronary artery and the posterior descending artery now let's take a look at the branches we can see it gives a branch to the right atrium and we can see that here this anterior branch to the right atrium and in 60 percent of the population the right atrial branch gives a branch to the sinoatrial lobe that is the essay nodal branch we also see it is giving multiple branches to the right ventricle and we can see them all the way here this is one branch this is another branch this branch that we see here the one which is running the longest distance this is the right marginal artery this runs along the right margin of the heart and it continues onto the inferior margin of the heart so this is the one which supplies the right ventricle this is the right ventricle when i turn the heart now we are in the right posterior coronary artery again we can see it is giving branches to the right atrium and it gives branches to the diaphragmatic or the inferior surface of the heart which is formed mostly by the left ventricle we notice these are the branches i'm going to lift up and we can see this branch this branch these are all branches of the right posterior coronary artery to the left ventricle and the posterior descending artery which runs in the posterior ventricular groove this supplies the posterior one third of the interventricular septum it also supplies the atrial ventricular bundle of his deep inside that branch we can see carefully is going inside so this is the full supply of the right coronary artery in this particular instance i've lifted up the right posterior coronary artery to see the فل اکسٹینٹ of the branches on them diaphragmatic or the inferior surface of the heart this is the right coronary angiogram to show the distribution of the right coronary artery this particular cadaver it looks like during life has sustained a diaphragmatic or inferior wallish chemia and that's why if you notice this portion of the diaphragmatic surface the appearance and the texture and the feel is considerably different this appears to be five roast so i would say that this area had undergone infarction necrosis and it has been replaced by five roast issue that's why the appearance is also quite different and neither was it covered by the usual fatty layer that we can see here so this is the right coronary artery now i'm going to shift again back and i'm turning the heart this is the left coronary artery that i have lifted up here and we can see it clearly here this is coming from the left coronary osteum the left coronary artery also initially it runs in the anterior part of the left atrial ventricular او the coronary groove and here also it is partially undercover of the left oracle and immediately thereafter it divides into two main branches and we can see the two main branches this is one branch and this is another branch this is the circumflex artery and this is the left anterior descending artery also known as the anterior intraventricular artery so let's take the lad first left anterior descending artery the anterior descending artery runs in the anterior intraventricular groove and like میںشن earlier we can see that it is tortuous it goes all the way across the apex and it goes a little bit onto the posterior intraventricular groove and we can see that here but it does not anastomous with the posterior descending artery that's an important point to remember as it descends down it gives septal branches which supply anterior two thirds of the intraventricular septal it also gives branches to the atrial ventricular bundle of his just like the posterior descending artery and more important it gives these following branches we can see one here we can see one here these are known as diagonal arteries or the d1 d2 there can be d3 this supplies the left ventricle so the left anterior descending artery is a major supplier of the left ventricle and a little bit of the right ventricle then we have the circumflex artery the circumflex artery it runs around and goes to the posterior coronary groove on the left side that is why it is called circumflex artery this is the circumflex artery and as it goes round you can see it is giving this branch here this is referred to as the obtuse marginal or the left marginal artery there can be more than one in which case we call them obtuse marginal one obtuse marginal two here we can see only obtuse marginal one and then the circumflex artery continues and it goes to the posterior coronary groove and we can see it is now giving multiple branches to the left ventricle and it is disappearing the circumflex artery also supplies the atrial ventricular bundle of his 80 percent of the population the av known is supplied by the right coronary artery in 20 percent of the population the av known is supplied by the left coronary artery this is the coronary angiogram to show the left main coronary artery and the lad and the beginning of the circumflex and this is the digital subtraction angiogram also to show the left coronary artery circumflex is shown in by arrow and the lad so these are the main branches that you can see supplying the heart again to repeat right coronary artery left main coronary artery left anterior descending circumflex let's quickly mention the incidence of coronary occlusion the lad is the most common site of coronary occlusion left anterior descending the second most common site is the right coronary artery the third most common site is the circumflex artery the fourth most common site is the left main coronary artery this is the left main coronary artery the fifth most common site for that i'll turn the heart the fifth most مصطرح پرمجانت کیا ہے اور دوسری مصطرح برے کا مالی ترجم کیا ہے۔ لہذا یہ ایک روشی ایک بہت بہت لیہ کیا ہے ، فیزان کے خروجہ م
