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 [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.

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 stop

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

However, the mental issues with 'not having a pulse' were almost insurmountable. You are alive, yet you have no pulse. Also, you are used to a constant movement inside your chest--that was also hard to get adjusted too, if they did at all.
However, just as in this story the patient's heart just re-started itself. Happy end

The next challenge, according to Anversa, is to find the source of the dividing myoctyes. "Are these cells a sub-population of known cells that retain the capacity to divide, or are they multiplying cells that originate from stem cells present in the heart?" he asks.
"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]
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.

I'd imagine that if more people had donated money to the church, Jesus would have been able to get to her sooner rather than later. Jesus loves us, but he needs money. So get off of your chair and donate some money now, so her little friend might be saved.

I'm no doctor, but I guess this technology would not be suitable for use in all cases, and that some patients still require more conventional treatment by other means - but hopefully that will keep advancing too. It's amazing to see progress like this being made in medicine and I too hope that it can help many more people.
I extend my sincere condolences for your loss and my best wishes for you.
