Girl's Heart Regenerates With Artificial Assist 184
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."

As one in three children recover from myocarditis on their own, the medics decided to wait and see if Jack's own heart could grow strong enough to work on its own without the need for a transplant.

presumablely her heart just needed a reduction in workload to allow it to heal, so they used this neat gadget to temporarily assist it until it was fully functional again.

I think that you are being a bit harsh there.
Survival figures vary - overall in the USA the five-year survival [americanheart.org] 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.

The second sentence in the article:
"Melissa Mills arrived at Edmonton's Stollery Children's Hospital last year after a sudden illness made her critically ill and a candidate for a heart transplant."
It wouldn't be slashdot if people didn't ask questions that were answered by the article

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.

A couple of them died from the effects of the surgery. Some others lasted long enough to finally get a transplant. But in several others their own livers managed to regenerate to the point where a transplant was no longer needed.
This led to a bigger study at 20 US research centers. The results were that artificial liver reduced mortality by 44 percent:

I really feel bad for you, OP. And that's like the understatement of the year.
Needless to say, the lesson here to any americans should be, If you're having a serious heart condition, GO TO CANADA.

"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: [hhmi.org]

Furthermore, with a transplant, she would be required to take anti-rejection medication for life and would suffer many more illnesses as a result.
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.
