And you can go inside the heart itself and repair the valves from the inside.

And the fact that pig heart valves have lots of these on them is the reason that you can't transplant a pig heart valve into a person easily.

This is actually a heart valve, which we engineered.

He can go inside, push inside of the heart, and really feel how the valves are moving.

And what happens is this can be implanted into a human heart without open heart surgery.

This is actually a heart valve that we've engineered, and you can see here, we have the structure of the heart valve and we've seeded that with cells, and then we exercise it.

Six weeks, these folds are now beginning with the papilla on the inside of the heart actually being able to pull down each one of those valves in your heart until you get a mature heart and then basically the development of the entire human body.

So this is actually a Dutch company, so I called them up, and I asked, Can I borrow a heart valve from you?

So, the most beautiful thing I found at least what I think is the most beautiful in the book, is this heart valve.

And the way you engineer this heart valve is the same strategy.

And once it's in the right spot, they remove the outer shell, and the heart valve, well, it gets this shape and at that moment it starts beating, instantly.

So one of the pioneers, for example, is Dr. Anthony Atala, and he has been working on layering cells to create body parts bladders, valves, kidneys.

The low tech bit is that it's literally a pig's heart valve mounted in the high tech bit, which is a memory metal casing.

Great and then I didn't hear from them for weeks, so I called, and I asked, What's going on with the heart valve?

Tal Golesworthy How I repaired my own heart

This was the only modality that can see the inner lining of the heart.

I had so many surgeries to put my neck back together, to repair my heart a few times.

But I said we can't get rid of it, because all the people who tried to transplant heart valves found out you can't get rid of that immunity.

There are materials that do this. Here are the heart patches.

Stem cells may be used to deliver growth factors to repair damaged heart muscle or be differentiated into heart muscle cells to restore heart function.

So you see the leaflets opening and closing of this heart valve that's currently being used experimentally to try to get it to further studies.

Anti clotting drug ticagrelor slashes the risk of repeat attacks for people with heart disease.

We take the scaffold, we seed it with cells, and you can now see here, the valve leaflets opening and closing.

It is dangerous for patients to recover from heart attacks at home.

Even trips to the dentist require that you take antibiotics, in case you get an internal infection on the valve.

Should they recover in a specialized cardiac unit in hospital, or should they recover at home?

This is a 21 year old Palestinian woman undergoing hymenoplasty.

They power how a cell replicates. They power our hearts.

The Government replied in June 1994 that he had died of a heart attack.

Heart disease, stroke, diabetes, spinal cord injury, muscular dystrophy, retinal eye diseases are any of these conditions relevant, personally, to you?

Stem cells may be used as building blocks to repair damaged scaffolds within our body, or to provide new liver cells to repair damaged liver.

Some 140,000 people have a heart attack in England every year, and a quarter of these go on to have another attack or a stroke.

International Centre for the Study of the Preservation and the Restoration of Cultural Property (ICCROM)

Again, fairly more complex organs, but by far, the most complex solid organs are actually the vascularized, highly vascularized, a lot of blood vessel supply, organs such as the heart, the liver, the kidneys.

He wanted to test out the question of, where is it that patients should recover from heart attacks?

Heart failure?

Heart diseases.

A heart attack?

Bum heart.

And if you had an injured organ, if you had a heart attack and we wanted to repair that injured area, do you want those robust, plentiful stem cells on the top?

Costa Rica, despite its rice industry failure, has also had some success with such policies. When the medical device industry was blocked from producing lucrative products like heart valves, owing to the lack of specialized firms to provide sterilization services, the government used incentives to attract such companies.

Heart healthy dinner is a very important part of restorative seafood.

Likewise, if you have the artificial valve option, you're committed to antibiotic therapy whenever you have any intrusive medical treatment at all.

We're doing this at the Cedars Sinai Heart Institute in the Women's Heart Center.
