What this trial studies

This observational registry aims to evaluate the 5-year outcomes of patients with degenerative mitral valve disease who have been treated using the NeoChord Artificial Chordae Delivery System, Model DS1000. The study will include both prospective and retrospective enrollment and will not require any additional invasive procedures beyond those typically associated with standard mitral valve repair. It is designed to gather real-world data on the effectiveness and safety of this treatment in a multicenter setting.

Who should consider this trial

Good fit: Ideal candidates are individuals with Grade III Moderate or Grade IV Severe degenerative or mixed disease mitral valve regurgitation who have undergone the procedure since December 31, 2016.

Not a fit: Patients with heavily calcified valves, active bacterial endocarditis, or complex mechanisms of mitral regurgitation may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide valuable insights into the long-term effectiveness of the NeoChord system for patients with mitral valve disease.

How similar studies have performed: Other studies involving similar approaches to mitral valve repair have shown promising results, indicating potential for success in this registry.
