🤩 Chinese Doctors Implanted the World's Smallest Artificial Heart in a 7-Year-Old Boy
In Wuhan, China, doctors performed a unique surgery: a seven-year-old boy with severe heart failure was implanted with the world's smallest artificial heart, which operates on a magnetic cushion. The rotating components of the miniature pump do not touch the walls of the mechanism, as the force of a magnetic field suspends them.
🤩 A Revolution in Pediatric Transplantology
In May 2024, the young patient was diagnosed with a life-threatening condition: dilated cardiomyopathy. The disease progressed rapidly, and soon, his heart could no longer pump enough blood on its own. The only solution for him was a transplant. However, finding a suitable donor proved difficult. Doctors decided to use an artificial heart to support the weakened organ temporarily.
The surgery took place in early April 2025. Over five hours, surgeons implanted an artificial heart in the boy that measures just 2.9 cm in diameter and weighs 45 grams.
The day after the surgery, the boy began breathing on his own, and his heart function stabilized and continued to improve. Now, he has a chance to wait for a new heart.
🤩 Why It's Important
The shortage of donor organs for children is a particularly pressing issue: in China alone, around 40,000 children with severe heart failure are hospitalized every year, but fewer than 100 patients receive transplants.
Until now, artificial hearts have primarily been developed for adults, and implanting them in children carries risks of complications. That's why the device created by Wuhan doctors in collaboration with the Shenzhen Core Medical Technology biotech startup represents a true breakthrough.
