About

This first-in-human study evaluates the safety and performance of the Vesalius Transcatheter Mitral Valve Repair (TMVr) System in patients with degenerative mitral regurgitation. The study will enroll patients who are at high or prohibitive risk for conventional surgical repair or replacement of the mitral valve. Participants will receive implantation of the Vesalius TMVr System and will be followed to assess clinical outcomes, device performance, and any adverse events.

Full description

This first-in-human study is designed to evaluate the safety and performance of the Vesalius Transcatheter Mitral Valve Repair (TMVr) System in patients with symptomatic, severe or moderate-to-severe degenerative mitral regurgitation who are at elevated surgical risk. The study will enroll up to five patients in Canada to assess procedural feasibility, technical performance, and short-term clinical outcomes following device implantation. Endpoints are based on Mitral Valve Academic Research Consortium (MVARC) definitions, including measures of procedural and device success, freedom from major adverse events, and technical achievement of device deployment. Safety, functional, and hemodynamic parameters will be monitored at predefined intervals, and follow-up will include assessment of valve function, adverse events, and device performance. This study will provide preliminary data to support the further development and evaluation of the Vesalius TMVr System.
