Core Insights - A 5-year-old child weighing 13 kg has successfully received a third-generation magnetic levitation biventricular artificial heart, setting a new record for the smallest age and lightest weight for such a procedure globally [1][2] - The surgery, lasting 9 hours, was a collaboration between Nanjing Children's Hospital and Tianjin TEDA International Cardiovascular Hospital, overcoming challenges related to the small thoracic cavity and balancing blood flow between the left and right hearts [1] - The child was diagnosed with a rare restrictive cardiomyopathy three years ago, with a significant deterioration in health leading to the decision for the artificial heart implantation due to the extreme scarcity of heart donors for young children [1] Technological Advancements - The development of the pediatric magnetic levitation ventricular assist device was based on the child's imaging data, resulting in a device weighing approximately 70 grams, designed specifically for low-weight patients [2] - This device features low hemolysis and high compatibility, addressing blood flow balance issues and reducing thrombus risk, significantly enhancing suitability for young, low-weight patients [2] - The transition from "external dependence" to "internal adaptation" allows more young patients with end-stage heart failure to access third-generation magnetic levitation artificial hearts, similar to adults [2]
