And let me actually show you where the blood vessels come from. These are called coronary vessels I just write the word coronary here.

It was the icu.

He's dying. Coronary blockage.

They're taking the de oxygenated blood away from the tissue of the heart.

He was not a healthy man. Mr. Rowe had quadruple bypass surgery before his 40th birthday.

Officially, they're characterizing that it was a coronary brought on by systemic shock.

Coronary vessels So, coronary artery and vein.

Or from the point of view of the person whose heart it is, it's on the left.

This right over here is called the left coronary artery or LCA.

So ischemia is deprivation of blood flow and oxygen downstream from this right over there.

Well, what is needed for the earliest possible warning of a heart attack?

Now, that inability to properly pump not just the cell, but the whole heart that is heart failure.

So this is a bypass operation, just like what Al Gore had, with a difference.

At this time this was an N of 20. Now there's an N of about 100.

But this one's kind of cool.

And you can see, it's lumpy bumpy.

If that happens the chances of surgery

And so when people talk about arteries getting blocked or getting clogged, they're talking about the coronary arteries.

That's what we call coronary artery disease, or heart disease.

Well, unfortunately that type of aneurysm is inoperable.

That's not very nice, but, after all, we had to find out what the answer is.

Basically, if you take an extremely sick patient and you give them a bypass, they get a little bit better.

His vitals are spiking.

And then, when the heart is ready to pump it back out, it goes into this artery, and the name of it is the aorta.

The syndrome, the female pattern now is called microvascular coronary dysfunction, or obstruction.

You can also sew bypass vessels directly onto a beating heart without cracking the chest.

Now, to start the journey, it's gonna have to out of the left ventricle and into the largest artery of the body.

It doesn't have any veins.

And the veins actually drain into a spot , directly into the right atrium.

And on the right you actually see a carotid artery that was engineered.

Hudson, run a bypass.

Remove the ties that bind...

Just like a car navigation, right?

Right it's gonna have to go away from the heart. So that's the aorta. The aorta actually has the little arch like that.

Now suppose you live in a certain part of a certain remote place and you have a loved one who has blockages in two coronary arteries and your family doctor refers that loved one to a cardiologist who's batting 200 on angioplasties.

Smelling salts.

If the artery gets nicked, how long do i have?

He is going to save my Maria and the baby with an operation.

And actually it stop there because of my arrows, but you can actually see now deoxygenated blood kind of goes from the right ventricle, through the pulmonary trunk, through the arteries and into the left and right lung.

I'm going to do some surgery here.

But, actually lungs are kind of interesting in the sense that there is a lot of mixing going on.

Remember the heart itself is a muscle. It itself needs oxygen.

And I hesitated there just to make sure I got that because it's taking blood away from the heart.

No lesions. No aneurysms.

MAP's at 55.
