Robotic system used in first-of-its-kind heart valve surgery in Hong Kong

Surgeons in Hong Kong have performed the world's first robotic-assisted tricuspid valve replacement on a human, marking a significant milestone in cardiac technology, researchers announced.

The procedure took place March 27 at the Prince of Wales Hospital. Using a specialized robotic system, a surgical team successfully implanted a replacement valve into a patient suffering from severe tricuspid regurgitation. This condition occurs when the heart's tricuspid valve fails to close tightly, allowing blood to leak backward from the right ventricle into the right atrium. Because the blood flows in the wrong direction, the heart is forced to work harder, which can eventually lead to right-sided heart failure.

To treat the condition, doctors often use a minimally invasive method called transcatheter replacement, which involves threading a new valve through the blood vessels using a thin, flexible tube called a catheter. However, this approach requires extreme precision. The new robotic platform, developed by the Institute of Automation of the Chinese Academy of Sciences and Jenscare Scientific Co, is designed to improve these outcomes by eliminating natural hand tremors, improving the accuracy of the implant, and potentially shortening the overall procedure time.

The system integrates high-precision motion control with "active safety constraints," which act like digital guardrails to keep surgical instruments within safe zones. It also features intelligent navigation to help guide the team through the heart's complex anatomy.

Beyond patient benefits, the platform improves safety for medical staff. Because the system allows the lead surgeon to operate the robot from a remote console, they can remain at a distance from the X-ray equipment used to visualize the heart during the procedure. This significantly reduces the surgeon's exposure to radiation and lowers occupational health risks. The institute noted that these remote capabilities could eventually allow specialists to collaborate on or perform surgeries across different regions.

Postoperative evaluations show the patient is recovering well. The Institute of Automation stated that the successful surgery marks a major step in moving this technology from the research and development phase into clinical application, laying the groundwork for wider use of robotic assistance in complex heart interventions.
