I found this article and was quite impressed with the science. If it works, it might offer an alternative to OHS and valve replacement for many?

I have duplicated the newpaper article below. It also has contact details for the European medical centre that seems to be offering this treatment.

Worth looking into? Has anyone else come across this?


------------------------------------------------------------------------


"In a pioneering procedure, stem cells are being used to grow new blood vessels to cure the problem forever.
Barbro Lowed, 61, a retired air stewardess from London, was one of the first to undergo the treatment, as she tells BOUDICCA FOX-LEONARD. THE PATIENT Barbro Lowed's pioneering treatment in Germany may have saved her life
One morning I woke up feeling really tired - I couldn't understand it because I'd had a good night's sleep. Then over the next few weeks I started to feel breathless - it was a struggle even walking upstairs, which was odd as I've always been so fit and healthy.
After about two months of this, my feet suddenly swelled up overnight - I couldn't even get my shoes on - and my throat felt really tight. My husband was extremely worried, so he insisted on taking me to the Chelsea & Westminster Hospital, which is nearby.
I couldn't believe it when, a few hours later after undergoing tests, doctors said I had heart failure; I thought it was something 80-year-olds got.
The doctors said my heart wasn't pumping blood around my body fast enough. They couldn't say why this had happened, but one of the valves was damaged, which meant my heart was struggling so I wasn't getting enough oxygen.
The bottom line was I'd need surgery to replace my heart valve with a plastic one.
Unless it was repaired, my heart would steadily worsen, until it couldn't function any more. Even though I needed the operation straight away, the NHS waiting list was two years, which really worried me.
After six months, with no sign of an operation date, I was getting desperate. I felt dizzy and lethargic all the time and couldn't even walk to the local shops without struggling for breath.
Then I read an article in the Daily Mail about a man who'd had his heart failure cured in Germany using stem cells. The stem cells had been taken from his bone marrow and implanted in his heart. Because stem cells can turn into almost any type of cell in the body, they'd turned into new blood vessels and restored his heart.
No one was performing the procedure in the UK, but when I searched on the internet I found four doctors in Germany doing it. I wrote to all of them, and a month later Professor Andreas Zeiher wrote back. He said I could take part in a pioneering stem cell transplant programme to repair the damaged valves.
He explained that the procedure would involve taking stem cells from my hip and injecting them into the heart valve - the whole process would take three days.
I knew straight away I wanted to have it done, although it was expensive - £7,000. But I would have done anything to feel normal again.

What also appealed was that the procedure didn't involve major open heart surgery, which would have been necessary to have the valve replaced in the UK.
I flew to Frankfurt for the operation in February 2005. First, I had various tests, including an echocardiogram (an ultrasound of the heart). These confirmed I had weak valves. Professor Zeiher thought the damage had been caused by an infection a couple of years before, when I'd had two teeth removed.
The stem cell technology allowed doctors to give Barbro a new lease on life
I hadn't noticed any symptoms, but it was a relief to learn what had caused the heart failure in the first place. My NHS doctor had been vague, saying I must have had a heart attack, even though I knew I hadn't.
I had the operation the next day. First, the stem cells were extracted using a eedle; this took about five minutes. Then I waited for five hours while the cells were cleaned and processed.


For the actual transplant, I was given a local anaesthetic in my leg. The doctors then inserted a tiny camera through an artery and sent it up the heart to locate my faulty heart valve. I was able to watch the whole thing on the TVs in the operating theatre; it was fascinating.
Then the stem cells were inserted through a hollow tube - a catheter - also via my leg.
Then I had to lie still for five hours to allow the puncture in my thigh to seal. I was allowed to fly home the next day with instructions to carry on as normal, but not to overdo it. After about six weeks, I noticed my breathing had improved. Professor Zeiher recommended a second injection to improve it further. He said most people need three jabs to get the heart fully functioning again.
This one made a real difference - my breathing continued to improve and five months later I was able to go for walks without sweating and becoming breathless. I felt fantastic.
Two months later I went for a heart scan with a London doctor Professor Zeiher had referred me to. It showed my heart valve had repaired itself, which was amazing. A further scan last year showed it is still functioning normally.
Now I feel better than ever and I walk every day. The stem cell treatment might have been expensive, but was worth it; I have my life back.

THE SURGEONAndreas Zeiher, Professor of Medicine and Chairman of the Department of Medicine at the Johann Wolfgang Goethe-Universitat in Frankfurt.

He says... Most people with heart failure manage with drugs such as beta-blockers, although around a third need open-heart surgery to carry out valve transplants or insert pacemakers because the problem is usually caused by damage to the valves or the heart muscle. But there are now other revolutionary ways to treat heart failure. The most exciting is with stem cell transplants.
Although bone marrow stem cell transplants have been around for more than 30 years, they have traditionally been used to treat conditions relating specifically to bone marrow, such as leukaemia, where it is no longer able to produce normal blood cells.
Using stem cells to repair other organs is something we have been researching only over the past seven years. But although it's considered a pioneering treatment, we're already starting to see positive results with cardiac patients.

Stem cells have this extraordinary ability to turn into other cells. They help the heart heal by encouraging the formation of new blood vessels, which brings more oxygen and nutrients to the heart muscle.
And as far as we know, unlike drug treatments, stem cell transplants have no undesirable side-effects. The process is also less risky than conventional open-heart surgery, as it doesn't involve a general anaesthetic, which is always a concern with a heart failure patient.
And while there are keyhole techniques available to replace faulty heart valves, it's better to try to cure the problem altogether. Transplanting the cells is a simple procedure lasting about 15 minutes.
First, we harvest the stem cells from the bone marrow under local anaesthetic - the easiest place from which to do this is the hip bone. I puncture the skin with a 2mm diameter needle and then insert a syringe to collect 50ml of bone marrow.
This is sent to the laboratory and the stem cells are extracted. We then inject them into the blood vessels that supply the heart with oxygen. We don't know exactly how it works, but typically, four to six weeks after the stem cells are injected, the heart grows in strength and as such starts to pump better. This means blood flow improves and more oxygen is pumped around the body, making breathing easier.
Most patients need three injections over the space of a year, but Barbro was lucky that she made a major improvement after the second.
Unfortunately, this procedure is available at only one specialist clinic in the UK, St Bartholomew's Hospital in London, but I hope it will soon become more widely available, as it is such a major advance.
Barbro was one of the first people in the world to have the procedure and she's a great example of what it can do.

Skeptical. Very.

This wouldn't improve stenosis or regurgitation ("insufficiency") with calcification, which most commonly have. The calcification itself becomes the issue over time.

Just as a matter of practicality, I can't imagine how it gets "injected" into the leaflets of a beating heart, even from a catheter. If it were just released, it would simply flow away with the blood.

She doesn't say which valve, but somehow I'm thinking if there's any possibility of this working, it must be the mitral valve.

It's also a closed loop. If the story is accurate, she is sent to a particular doctor in London for an echo that tells her she's better. Note that heart failure waxes and wanes over time, so her feeling somewhat better is not necessarily telling.

I hope it's true. I think it's not, at least not as described above. We've gotten plausible articles from Europe and the US about miracle cures and wonderful new artificial valves which require no warfarin in the past. No further word from any of them.

Best wishes,
 
Interesting. I googled the surgeon's name and found many links, including the actual link to the newspaper below.

http://www.dailymail.co.uk/health/a...aulty-heart-valve-rebuilt-stem-cells-hip.html

I believed the stem cell therapy used to strengthen heart muscles is real and promising. Several sources cited that the injected cells can turn into new heart muscle cells or blood vessels. But I believe the heart valve is a different kind of tissue and I too wonder how stem cells can be delivered to the damaged valve. Is she improved from heart
failure because of her heart valve truly revived or just her heart muscle ? Perhaps someone could write to the surgeon for clarification ?

From my research I found Dr.Andreas Zeiher of University of Frankfurt in many news, seminars, papers, so I think he is real and active in this field.

Note that two years ago there is a report that heart valve can be grown from stem cells but that's outside human body. See http://news.bbc.co.uk/2/hi/health/6517645.stm
Wondering how far they are progressing now.

All the Best,

Fascinating. I'm certainly not sure I'd have been brave enough to try this, so I'm glad there are people out there willing to be guinea pigs! Eventually, maybe there will be some true benefit. Wondering if the "fix" was permanent, or just a temporary stay until the subject needed open heart surgery.

Thanks for sharing. It's good to have all the news put into the forum.

There has been some informally verified work done with improving heart muscle function with stem cells delivered by catheter. I don't have a problem with that aspect of it. However, I do not see anything that makes this valve claim plausible here except a probable misconception on the part of the young lady as to what was actually improved. I do not believe the heart valve was fixed directly: I don't believe it could practically be physically injected in use.

So, if there was valve leakage and that leakage went away, it could have been caused by a greatly enlarged heart muscle returning to a smaller, more normal size, so the valve once again seated properly.

This would not reverse calcification, make a bicuspid valve into a three-leafed valve, or repair torn leaflets or stretched mitral chordae. There is no discerned biological imperative or blueprint to do so.

If it improved myxomatous tissue in and around valves by filling in more normal tissue, that would be completely new and wonderful. I don't think that's what happened here.

Best wishes,

Please tell me if I am wrong but I thought that adult stem cells were
fairly useless for healing different body tissues,I thought only fetal stem
cells could do this level of healing since they could grow into any tissue,
including cardiac ...? Maybe I'm mixed up or behind in information--all too
possible:rolleyes:

Actually almost evey advacement made in this area is with adult stem cells. Everything from growing new blatters for children to new heart valves and and the possibility to "grow new hearts" from pig hearts. The advantage of adult stem cells that come from your own body is that there is no chance of rejection. They are being used to cure athritis and trials are on going in TX where they are injected into heart and cure congestive heart failure. Embro stem cells can be rejected and or grow out of control where adult stem cells are self limiting.

All that being said the OP might work if there was no narrowing and calsification. However the only research I have seen is where adult stem cells are placed on a "scaffold" and they grow a new heart valve in a lab and place it in the body the traditional way. This will be your own heart vavle and should last a life time.

With all the fanfare I know of no major advancement that has been made with embronic stem cells.
 
Regenerative Medicine

Regenerative Medicine

My wife had me watch a TV show recently that covered this concept - I believe it was classified as regenerative medicine.

Dr. Oz, who I believe is also a cardiologist was EXTREMELY excited about these advancements.

I walked away from this feeling that there was some merit in this technique and that it won't be long before additional facts may be understood enabling this to potentially be an alternative to some surgeries.

I continue to watch this space, but don't think it'll be ready here in the US by the time I have my surgery in in August.:(

Thanks John, I think the word that got stuck was "self limiting" - I probably
misconstrued this as being negative when in fact it is actually more of a
help than hindrance in this case -Dina
 
Verification of Barbro Lowed's story in the Daily Mail

OK, I have an interest to declare. I am Barbro's husband. My daughter said she had seen Barbro's name on the web so I had a look and found this site amongst others.

The Daily Mail is a little folksy in its reporting and she never actually said that she thought that heart failures were only suffered by eighty year olds but this is a true story. Disbelievers can contact Professor Zeiher who is a genuine, highly reputable and qualified cardiac surgeon in Frankfurt. Since the newspaper articles in the Mail and the 'Dagens Nyheter' in Sweden on 21st Sept '06, Prof Zeiher has had enquiries and actually treated over thirty people with stem cells as a direct result of Barbro's story.

Barbro had severe congestive heart failure. Coronary artery disease was ruled out following coronary angiography and the cause of the problem was identified as dilated cardiomyopathy with considerable mitral valve regurgitation. She did not have valve calcification which one blog writer said was a common problem. Bone marrow progenitor cells were injected into the muscles of the weakest (left) valve by the catheterization described. Three months later the same therapy was performed on the right hand valve muscles. She has had regular check ups with her specialist heart doctors at the Heart hospital in London ever since, has been feeling well and has considerably reduced the medication originally prescribed. She now only takes 3mg of betablocker, 5mg of ramipril and 75mg of aspirin every day. On 24th Oct '05 she had a defibrillator (ICD) implanted which has in all the time since only once caused a noticeable intervention. The principal reason why she had it fitted was to so that every three months her heart could be monitored as she is technically a research subject.

I am not a medical person at all but I do keep coming across newspaper mention of stem cell treatment for many different medical problems and so do think that stem cell therapy is a genuinely promising way forward for a very wide range of ailments including treatment of livers and MS and I would not be surprised if certain cancers could eventually be included. Research is being carried out in a number of countries and now including the USA.

A part of the problem in my view is that the general public appear to be suffering from the mistaken belief that all stem cells come from embryos and then are perhaps sometimes subjected to objections from various groups implying deliberately having children for the specific purpose of using their embryonic stem cells. We all have stem cells within our own bodies which have regenerative capabilities and, importantly, since they are of our own body, there is no danger of their being rejected. However, since embryonic stem cells are in fact the purist, I think it could actually be a good idea, costs permitting, to bank one's own embryonic stem cells for future use.

Finally, I would just like to say that Barbro's condition has improved so much that she now lives a normal life and, whilst this therapy may not suit all cases, I would urge people, if the heart failure is not too far advanced, to take advice from a range of qualified specialists but at least to consider it as a serious alternative to surgery.
