Gentler Fake Heart to be Tested in 2018

Existing replacement heart pumps apparently have a bit of a problem, in that they're bulky and their aggressive pumping action can damage the blood by being too rough with it. Hence a smaller one that goes a bit easy on the blood coming up for a trial in 2018. Read More >>

This Heart in a Jar Could Make Heart Transplants Safer

What looks like a prop from a steampunk movie is actually a partially decellularised heart in a bioreactor. And this heart has the potential to save the lives of heart attack patients, and, one day, people who need heart transplants too. Read More >>

Scientists Just Grew Human Heart Tissue That Beats With Total Autonomy

Coming fresh on the heels of the news that scientists are successfully 3D printing live, working, mini human kidneys, a new report in Nature is giving another burst of hope to the future of organ transplants. For the very first time, a research team has been able to grow human heart tissue that beats totally autonomously in its petri dish home. Read More >>

Researchers Use Circuit Printer to Make Functional Heart Muscle

Growing replacement organs in a lab and transplanting them is science-fiction dream-turned-very-possible-reality, but so far it's been limited to simple tissues. Yesterday, MIT researchers published findings on their successful attempts to build functional heart tissue, using a modified machine originally meant to build integrated circuits. Read More >>

The World’s Newest Artificial Heart Is Half Cow, Half Machine

Using cow parts to save ailing human hearts isn't anything new—you could even be sitting next to one of our more bovine brethren right now and think nothing of it. But the newest cow-to-heart integration takes a bit of a deeper dive into science fiction land. Soon, a French medical company will begin testing a "bioprosthetic" heart on actual human patients that is part cow, part synthetic, and loaded with software. Read More >>
