Active Surveillance and Safety/Efficacy Evaluation of Innovative Devices for Structural Heart Disease Intervention (ASSEE-SHD)

26. september 2026 oppdatert av: Lijun Fu, Shanghai Jiao Tong University School of Medicine

Establishment of Active Surveillance and Safety and Efficacy Evaluation Indicators for Innovative Devices Used in Interventional Treatment of Structural Heart Disease

This study aims to establish an active surveillance system to evaluate the safety and effectiveness of innovative medical devices used in the interventional treatment of structural heart disease. The devices of interest include a biodegradable patent foramen ovale (PFO) closure device and a transcatheter mitral valve edge-to-edge repair system. Clinical information from patients receiving these devices during routine clinical care will be collected and analyzed. The findings will help evaluate the safety and effectiveness of these devices and support the development of appropriate clinical evaluation indicators and long-term monitoring strategies.
