Smallest Mechanical Heart"

China: Child Recieves World’s Smallest [Magnetically Levitated] “Artificial Heart”! (28.4.2025)

The device, measuring 2.9 centimetres in diameter and weighing 45 grams, is the smallest and lightest of its kind globally, according to the hospital.

Operating at an optimal speed range of 1,500 to 3,600 revolutions per minute, it establishes a stable blood circulation system within young, low-weight paediatric patients, the hospital said.

This artificial device functions like a high-powered motor, allowing fatigued ventricles to rest while maintaining systemic blood circulation, effectively helping acute heart failure patients through critical periods with both minimally invasive procedures and notable efficacy, CNR reported.
