Girl's Heart Regenerates With Artificial Assist

Socguy writes with news about a 15-year-old girl who has become the first Canadian to have an artificial heart removed after her own heart healed itself. "Doctors at the Stollery Children's hospital implanted the Berlin Heart, a portable mechanical device that keeps blood pumping in an ailing heart, so she could survive until a transplant became available. But over the next few months, Melissa's overall condition improved dramatically, and her heart muscle regained much of its strength. After 146 days on the Berlin Heart, Melissa underwent surgery to have the device removed."

      I think that you are being a bit harsh there.

      Survival figures vary - overall in the USA the five-year survival rate is 71.2 percent for males and 66.9 percent for females. Its better than that in some units. This person's survival after a transplant would be alot higher than this as young people do better on average than older recipiants.

      Over 2/3 alive at 5 years, and actually pretty similar at 10 years - bearing in mind that most of bad outcomes are in the first year, and that this is all causes of death, including deaths that were unrelated to the transplant.

      The main bad thing about heart transplants is not getting enough hearts.

      Having said this, you will see a significant number of people who do not require transplantation due to spontaneous recovery of function.

      They still require two major operations - the VAD insertion and the VAD removal - so its not exactly a walk in the park.

      And the VAD's such as this can have quite significant complications. The are good but not necessarily the only solution.

If she makes it to the 10 year mark, she'll be 25, and likely at her prime. What's the mortality rate for 20 years? I don't imagine it to be very high, even for children.

      Granted, given her situation, she might have been dead in a year without a transplant, and 10 or 15 years is better than one. But transplants shouldn't be the final answer. Transplants should be more like asprin: a stopgap measure to continue functioning normally until the body finishes healing itself. Unfortunately, transplants are pretty final these days, and no healing can occur afterwards...

      Compared to death or a short bedridden life, a transplant is a great option. However, where feasible, a temporary VAD and recovery of the original heart is much better.

      There is a form of heart transplant where the new heart is connected in parallel with the original. The procedure is more complex but offers better survival should rejection occur. I'm not sure how it does for survival in general vs. a full replacment.

Especially in kids and especially in cases where the heart has been damaged by inflammation. It is a safe bet really - if it heals good, if it does not the patient has a much better chance to survive until a suitable transplant is found.

      It's not that the heart "healed". What happens after a serious injury to the heart (whether a heart attack, viral infection, or anything else), is that the heart becomes weaker and tries to adapt. Things that physicians do to help the heart adapt in the right way (as opposed to the wrong way) include assist devices that will pump the blood forward. These include artificial hearts, left ventricular and biventricular assist devices, and intra-aortic balloon pumps. Other things that help people along are medications that help the heart rest and prevent the maladaptation that the heart will do on it's own if left to it's own means (the maladaptation is known as negative remodelling).

      Given enough time, the heart may beat more effectively. I know a number of people whos hearts are pumping out less than 10 percent of the blood that enters it (normal is to pump out ~60 percent). Some of these people are crippled and await heart transplantation. A few, however, are out chasing the girls (and boys), and you wouldn't have any idea that they had a medical problem until you saw the number of medications that they take to stay well.

    "There are preliminary indications that primitive cells like stem cells exist in the human heart. Stem cells may have the ability to develop into the various cardiac cell types and form new healthy functioning myocardium. If we can prove the existence of cardiac stem cells and make these cells migrate to the region of tissue damage, we could conceivably improve the repair of damaged heart muscle and reduce heart failure," says Anversa.

    Cardiac muscle cells, however, do not reproduce after a certain point:

    Not all cells from multicellular organisms are still able to divide, though. Once the heart is full sized, the heart cells in a human body do not divide anymore. They no longer have that ability. When a person has a heart attack and some heart cells die, the heart is permanently damaged the heart can't just replace those dead cells.

    According to Doris Taylor (Departments of Medicine and Surgery at Duke University Medical Center. She did post-doctoral work in cardiac (heart) molecular biology at Albert Einstein College of Medicine in New York.)

    The heart cannot repair the damaged muscle because its muscle cells cannot reproduce, Doris explains. You are born with all the heart cells you will ever have. Your heart grows because the cells become larger, not because they multiply. However, other muscles do have the ability to repair themselves because they contain cells called myoblasts, which can reproduce.
