I was fascinated to read about the baby boy who survived 120 days on an artificial heart. What an incredible device. Now here comes another news story. Same device, but this time it's about a Canadian teen. Fifteen-year-old Melissa Mills spent 146 days connected to her artificial heart. During that time she and her family were waiting for a transplant opportunity. Like the UK baby, however, her heart healed itself and she's now doing just fine - no surgery required! "For sure it's a miracle," one heart specialist was quoted as saying.

Even a few years ago, it would have been considered just about impossible for someone like Melissa to survive without a heart transplant. Indeed, it was not altogether certain Melissa would survive her illness, and her parents were told to prepare for that possibility. This particular device, also called a "Berlin Heart," is what's made the difference in both this and the UK baby case.

The Berlin Heart was designed especially for children, with the intention of keeping sick children alive during long and harrowing waits for heart transplants. However, cardiologists have been delighted to find that hooking a child up to the Berlin Heart not only keeps the child alive, but also gives the heart a chance to rest and repair itself. Heart cured. Wow.
