hi let's talk about the cardiac veins in this video we'll really focus on the greater system
so we won't be discussing the febsion veins we'll we'll talk about the the veins that are
quite superficial and very evident from a gross perspective
and let's begin with the great cardiac vein you can see a little bit of the great cardiac
vein let me just change colors here to really honor our venus brothers and sisters
here you can see it ascending up typically it's more superficial
than the anterior interventricular branch but it's occupying that same niche of the
generalized region of the anterior interventricular sulcus so it will be a
sulcus body with the anterior interventricular branch now as we wrap around into the coronary
sulcus now we're on the posterior inferior portion of the heart so this is the diaphragmatic surface
there we can see the the base of the heart there here is the opening for the inferior vena cava
here's our coronary sulcus there let's see what we can see so to speak so let me erase
all of this and coming around that corner where we left off in the coronary sulcus
is that great cardiac vein and it's emptying into this very large dilated vessel called the
coronary sinus the coronary sinus lives in the coronary sulcus and it is the collecting
vein of the greater system before it heads into the right atrium so in the
posterior interventricular sulcus which we can see coming up here we have a middle cardiac vein
so the grate is coming around there the middle comes around there we're going to have a small
come around that way but we're going to have to
approach that from a different perspective the small cardiac vein is going to be in
association with the right marginal branch we can see that snaking along there
helping to drain the right ventricle
and while we're at this orientation we can also see some of my favorite cardiac veins
they're my favorite cardiac veins because they really buck the system the greater system that is
because most greater system veins are going to drain into the coronary
sinus these anterior cardiac veins
help to drain the right ventricle and they are going to independently enter into the right atrium
and there can generally be between three to five anterior cardiac veins and as you dissect
typically you know i recommend dissecting in the direction of vasculature
but as you dissect through the epicardium at least at this
coronary sulcus here i'd recommend dissecting in this direction so that you can first find
these anterior cardiac veins and preserve them before you dig out the right coronary artery
so these are the cardiac veins named so because they drain the myocardium or the heart of blood
we've discussed the coronary sinus and the great middle and small cardiac veins which drain into it
as well as the anterior cardiac veins which do not drain into it thank you very much for your time
