Blood supply of the heart

[@Sleduuschaya]

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 KZbin To the point, only the information is spoken and (again) is clearly shown. Thank you. Very useful, very impressive.

[@omarkousa9904]

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!

[@akram.jaffar]

Thank you Omar for your nice words and best wishes in your fellowship. You are such a hardworking and ambitious man.

[@fahmikemal4728]

Coronary circulation kept me confused & you've now cleared it. Jajakallah kheyr from Ethiopia.

[@akram.jaffar]

Thank you!

[@Silverwing_99]

Simply outstanding - best CV-coronary tutorial i have ever had. 10/10 Thanks

[@akram.jaffar]

@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).

[@mhak-10]

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.

[@akram.jaffar]

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.

[@tommyswenson_]

Excellent coronary blood supply video. Thank you, dr. Jaffar.

[@shehata999]

Danke schön, Dr. Jaffar.

[@Sleduuschaya]

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.

[@LittlePurpleBook]

Great and simple explanation! Very helpful for reviewing heart anatomy! Many thanks, Professor!

[@akram.jaffar]

@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.

[@lutalobossa9102]

Fantastic video. Thank you very much.

[@drsaimakhan3621]

Thanks really loads sir.. May God Bless u for such a great help to students like us..

[@laxu49]

Keep doing this please. Thank you so much

[@KMacFNP]

Thank you Dr Jaffar. It gave me a more in depth understanding about the coronary circulation.

[@souvikd17nov]

Thank you so much for making anatomy easy and interesting.

[@MXMGamer]

This is really good. A very useful review for my exam next week يعطيك العافية دكتور أكرم! :)

[@aziz506x]

This was clear and useful ... Thanks a lot

[@JoaosLab]

Great diagrams and clear explanation. This video helped me review this topic.Thank you so much, Dr Jaffar!

[@akram.jaffar]

@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.

[@ravindranathkamath1577]

Thank You Very Much Sir!!!!.... U have thought much better than my teacher .... Hats Off To You....😊😊😊😊

[@egyptempire2030]

Danke schön , Dr. Jaffar

[@noorjaddou8034]

[@akram.jaffar]

+Noor Jaddou Good to hear that it is helpful for doctors as well :-)

[@ixoralily]

thank you..it helps A LOT....this is awesome video...thanks again...

[@digambarpanchal1859]

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😊

[@akram.jaffar]

Best of luck!

[@HarrySingh9478]

Excellent, very informative and beautifully narrated

[@lincolndlp9731]

Highly instructive.

[@maliram5637]

[@angelawilks3641]

Great have an exam in two days and this really helped

[@lovelyg628]

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.)

[@tintswalomakaringe3770]

Thank you so much sir; your video goes very well with my class notes. It as if you wrote the notes I am reading!

[@akram.jaffar]

+Tintswalo Makaringe what a coincidence! Best wishes

[@MrTrimetrin2]

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.

[@bomhayhay]

شكرا د . اكرم جعفر ...Thank u D.

[@DrHumairaKaySath]

sir aap drawing k liye kon sa software use kerty hein ? your videos are v good

[@EvesAdam]

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???

+Dhwani nagda thank you!

[@SarahSmith-bs4nl]

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?

[@sandraf425]

I was wondering the same!!! I think they are switched lol

[@hameedniazi]

Just depends on whether you look at section from above or below.

[@nicolamaraldo]

excellent. thank you.

[@RT060789]

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

[@mohammedkhalaf2114]

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?

[@akram.jaffar]

The coronary sinus is located posteriorly; you are correct, I should have made it dotted. Thank you for your interest in the channel.

[@hameedniazi]

Thank you sir , that was awesome

[@sandwitht6264]

[@kackieedgcumbe8477]

thanks a lot

[@MrTrimetrin2]

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.
