- This session describes the blood supply of the heart based on sketches that trace the course, branches, and tributaries of the coronary arteries and cardiac veins.
00:05 Sketching the outline of the heart
01:29 Right coronary artery
05:25 Left coronary artery
06:02 Anterior interventricular artery (LAD)
07:55 Circumflex artery
08:27 Coronary dominance
09:24 Blood supply of the conducting system of the heart
10:27 Venous drainage of the heart
After watching this video it is expected that you will be able to:
• Identify the origin of right and left coronary arteries from aortic sinuses.
• Identify and describe the course of the right coronary artery and its common branches:
- SA nodal artery.
- Acute marginal artery
- Posterior interventricular artery
- Atrial and ventricular branches.
- AV nodal artery
• Relate the clinical nomenclature of coronary arteries to the anatomical terms.
• Map the area of supply of the right coronary artery
• Identify and describe the course of the left coronary artery and its main branches:
- Anterior interventricular artery.
- Circumflex artery.
• Enumerate the branches of anterior interventricular and circumflex arteries.
• Map the area of supply of the left coronary artery
• Identify the sites of anastomosis of coronary arteries.
• Explain the dominance of coronary circulation.
• Outline the blood supply of the conducting system of the heart.
• Describe the blood supply of the interventricular septum.
• Outline the veins on the surface of the heart and relate them to the accompanying coronary arteries.
• Describe the location, formation and opening of the coronary sinus.
• Identify the tributaries of the coronary sinus.
• Identify the oblique vein of the left atrium.
• Enumerate and locate veins draining the myocardium other than the coronary sinus: smallest cardiac veins and anterior cardiac veins.

I saw this video 10-years ago when I was in my second year at the university, and here I am back again to watch it during my first year of cardiology fellowship! Thank you very much, Dr. Akram, for everything you did for us during medical school!
Thank you Omar for your nice words and best wishes in your fellowship. You are such a hardworking and ambitious man.
Coronary circulation kept me confused & you've now cleared it. Jajakallah kheyr from Ethiopia.
Thank you!
Watching this now during my first year of Cardiology fellowship! Thank you so much for all what you did during med school and what you continue to do now. Would ve loved it if you included Ramus Intermedius in your video.
Thank you for your interest and your compliments. You are right, I only dealt with variations of the branching of coronaries and not their origin.
Great and simple explanation! Very helpful for reviewing heart anatomy! Many thanks, Professor!
Great diagrams and clear explanation. This video helped me review this topic.Thank you so much, Dr Jaffar!
thank you dr. Akram :-) very helpful for quick review
+Noor Jaddou Good to hear that it is helpful for doctors as well :-)
This is really good. A very useful review for my exam next week
يعطيك العافية دكتور أكرم! :)
thank you Dr Jaffar, just to make a point, there are no 2 posterior sinuses and one anterior. the aortic valve has one posterior sinus/cusp and two anterior sinuses. the right coronary artery arises from the right sinus and the left coronary artery from the left sinus.
Thank you so much sir; your video goes very well with my class notes. It as if you wrote the notes I am reading!
+Tintswalo Makaringe what a coincidence! Best wishes
@MrTrimetrin2 Thank you for your note. I really appreciate your interest in the subject. The basis for naming cusps of the aortic and pulmonary valves can be confusing. Some textbooks are using the embryological nomenclature and are referring to right, left and posterior cusps in respect to the aortic valve cusps/sinuses (Moore KL et al. (2013): Clinically Orientated Anatomy. 7th Ed. Lippincott, Williams & Wilkins. Philadelphia. p153).
no, dominance refers to the artery from which the posterior descending artery originates and not the vessel supplies the greater absolute myocardial muscle mass or the AV node. a right dominant system occurs in about 80% of patients, with a left dominant system in 10-15% and co-dominant system in approximately 5% of patients. left dominance also occurs slighty more frequently in males and in patients with a bicuspid aortic valve.
Thank you sir , that was awesome

Superb
Thank you!

RCA does not supply a) right atrium b) part of left atrium c) post 2/3 of interventricular septum
c
@MrTrimetrin2 However, other anatomy textbooks are referring to one anterior and two posterior aortic cusps in the way I referred to them in the video (Sinnatamby CS (1999): Last’s anatomy, regional and applied. 10th Ed. Churchill Livingstone. p197). This is based on the location of the cusp/sinus postnatally.
The narration is wonderful - no "ummm's", no "OK?'s", no "do you understand's" and other "parasite words" or fillers. No unnecessary pointer flailing as is often in the presentations on RUclips To the point, only the information is spoken and (again) is clearly shown.
Thank you. Very useful, very impressive.
Fantastic video. Thank you very much.
My LAD is twisted and partially blocked. I am 68.
@adamwhitee Regarding the blood supply of the conductive system, kindly watch from 9:25; the AV-node, in 80% of the cases is supplied by the right coronary artery at the inferior surface of the heart. In 20% of the cases the AV-node receives its blood supply from the circumflex of the left coronary artery. LAD does not supply the AV node, but provides blood supply to the AV bundle.
Thanks really loads sir.. May God Bless u for such a great help to students like us..
This was clear and useful ... Thanks a lot
sir aap drawing k liye kon sa software use kerty hein ? your videos are v good
Keep doing this please. Thank you so much
Excellent coronary blood supply video. Thank you, dr. Jaffar.
WELL EXPLAINED ...THANK YOU SOMUCH SIR
Thank you so much for making anatomy easy and interesting.
Excellent, very informative and beautifully narrated
THAT AWESOME FEELING WHEN YOU UNDERSTAND A COMPLEX TOPIC LECTURE VERY WELL AND ARE ABLE TO RETAIN IT ,,,,,,,,,,,I AM GETTING THE SAME :D..........(THAT TOO ANATOMY WHICH IS SO VOLATILE AND YOU NEED SO MUCH OF PRACTICE.)
ThnX 4 the upload jst one question though, which vessel would perfuse the AV-node the branch arising from the right c.artery or the branch from the LAD???
Very useful and beautiful thank a lot sir
Thank you doctor.but why do you make the coronary sinus with deep coloured line.lsn't it in the posterior part of interventricular groove?
The coronary sinus is located posteriorly; you are correct, I should have made it dotted. Thank you for your interest in the channel.
Hi, on your picture showing the transverse cut on the heart (RV and LV) aren't the Anterior Interventricular and Posterior Interventricular switched. Shouldn't the AV on left show the Posterior Internventricular "on top" of the picture and the LV Anterior show up the on "bottom" of the picture?
I was wondering the same!!! I think they are switched lol
Just depends on whether you look at section from above or below.
Thank You Very Much Sir!!!!.... U have thought much better than my teacher ....
Hats Off To You....😊😊😊😊
Simply outstanding - best CV-coronary tutorial i have ever had.
10/10
Thanks
thankyou so much sir....could you plzz upload more videos..i secured highest marks in first semester..just because of your videos...very informative..thyroid was supereb....alla hafis
well done Akram many thanks
Great video sir! I saw this video in my 1st yr MBBS while learning anatomy. Now again watching this video to revise my cardiology in my final yr MD😊
Best of luck!
Wow. Bravo! Very thorough, very clear, great representation form different planes of view.
Venous drainage is presented - FINALLY! - which is hard to find in this detail anywhere online! Most of the attention (in other sources) is paid to the arteries - I am very glad I stumbled upon your presentation.
that was a superb lecture sir
+Dr.ramesh mada thanks!
This is the best.
Thank you Dr Jaffar. It gave me a more in depth understanding about the coronary circulation.
Great have an exam in two days and this really helped
