00:00Hi, hello, welcome to meet you. Today we are going to discuss about coronary circulation.
00:06Coronary circulation is the circulation of blood in the blood cells of the bone.
00:11Now let's see the truth diagram. This is the superior vena cava and this is the inferior vena cava.
00:18The aorta and this is the pulmonary arteries.
00:27Coronary arteries arise from left and right sinuses of aortic bone, distal to the aortic bone.
00:34Within 2.5 cm of its origin, the left main coronary artery divides into the left anterior descending artery
00:46and the left circumflex artery which runs posterior to the heart shown in the dotted lines.
00:55And then let's draw the right coronary artery on the right side of the heart that supplies blood to the
01:02sinusoidal bone
01:05through a small branch called the nodal branch.
01:18The right coronary artery uses a small branch on the anterior side of called right marginal branch.
01:26The right coronary artery runs posterior to the heart and forms posterior descending artery
01:31that supplies blood to the atrioventricular bone.
01:40And these are the partitions.
01:43We divide the heart into 4 chambers.
01:46Now let's start with the left coronary artery branches.
01:51Now let's start with the right coronary artery.
01:57Now let's start with the right coronary artery.
02:00Now let's start with the right coronary artery.
02:01Now let's start with the right coronary artery.
02:03Now let's start with the right coronary artery.
02:05Now let's start with the right coronary artery.
02:10Now let's start with the right coronary artery.
02:11Now let's start with the right coronary artery.
02:13Now let's start with the right coronary artery.
02:20which gives branches to supply to the anterior part of septum and the anterior, later and apical
02:27walls of left ventricular. The left circumference artery that runs posterior to atrioventricular
02:36group which gives marginal branches that supply to the lateral, posterior and anterior parts
02:41of the left ventricular. Now let's discuss about right coronary artery. This is the s-a-node
02:53and the a-b-node. The co-s-a-m-as-de-hadi. Right atrium, left atrium, right ventricular
03:10and the left ventricular. The right coronary artery that runs in right atrioventricular
03:22group giving branches that supply to the right atrium, right ventricular and inferior posterior
03:28parts of the ventricular. The posterior descending artery runs in posterior interventricular
03:40septum. Do you know what physiological changes happen if there is an occlusion of the coronary
03:45arteries? Let's discuss about it now. There is a proximal occlusion of right coronary artery.
03:53It often results in sinus brady artery and may also cause AV flaws. And if there is an
04:02abrupt occlusion of right coronary artery due to coronary thrombosis, results in infraction
04:07of inferior part of left ventricular and often in the right ventricular. If there is an abrupt
04:12occlusion of left anterior descending artery or left circumflex artery causes infraction in
04:17corresponding regions of the left. Occlusion of left main coronary artery is usually fatal.
