What this trial studies

This trial evaluates the safety and effectiveness of the NeoChord DS1000 system for repairing degenerative mitral valve disease without the use of cardiopulmonary bypass. Participants will be randomly assigned to receive either the NeoChord device or standard surgical repair techniques. The study aims to determine if the new device offers advantages over traditional methods in terms of patient outcomes and recovery. It focuses on patients with moderate to severe mitral valve regurgitation and specific anatomical criteria.

Who should consider this trial

Good fit: Ideal candidates are individuals with Grade III or IV degenerative mitral valve regurgitation who are suitable for mitral valve repair.

Not a fit: Patients who have had prior mitral valve surgery or require additional cardiac procedures may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to less invasive mitral valve repair options with improved recovery times for patients.

How similar studies have performed: Other studies have explored minimally invasive techniques for mitral valve repair, showing promising results, but this specific device's approach is relatively novel.

Eligibility criteria

Show full inclusion / exclusion criteria
Inclusion Criteria:

* Is a candidate for mitral valve repair with cardiopulmonary bypass
