Transcatheter vs. Surgical Repair for Degenerative Mitral Valve Disease

Official title: Transcatheter vs. Surgical Treatment of Degenerative Mitral Regurgitation: A Comparative Study of Clinical Outcomes, Patient Experiences, and Mechanistic Insights With Multimodality Imaging

Run by Cedars-Sinai Medical Center · NCT07605715 · Data updated 2026-11-12

This study compares TEER, a catheter-based repair, with traditional surgical mitral repair in people aged 60 and older with degenerative mitral valve disease to see which approach works better in the long run.

Is this trial a fit for you?

Likely a good fit

Adults over 60 with degenerative mitral regurgitation who have not had prior mitral interventions and who are eligible for either TEER or surgical repair.

Probably not a fit

Patients with prior mitral interventions or contraindications to the procedures may not benefit from the study conclusions.

What this trial studies

This is an ambispective cohort study that combines prospective and retrospective data to compare long-term outcomes after transcatheter edge-to-edge repair (TEER) versus surgical repair for degenerative mitral regurgitation. Researchers will collect clinical, procedural, and follow-up information, with advanced imaging like cardiac MRI to identify predictors of left ventricular dysfunction and other outcomes. Patient-reported recovery and quality of life will be measured using validated tools. The study aims to refine care for higher surgical-risk patients by identifying which treatment approach offers better durability and recovery.

Why it matters

Potential benefit: If TEER shows comparable or superior long-term outcomes, it could offer a less invasive option for older patients or those at higher surgical risk.

How similar studies have gone: Prior studies in this field have shown meaningful insights for TEER versus surgery, but long-term comparative data in degenerative disease remain limited, making this observational work valuable.
