Transcatheter vs. Surgical Treatment of Degenerative Mitral Regurgitation (DMR)
Transcatheter vs. Surgical Treatment of Degenerative Mitral Regurgitation: A Comparative Study of Clinical Outcomes, Patient Experiences, and Mechanistic Insights With Multimodality Imaging
The goal of this observational study is to compare the outcomes of transcatheter edge-to-edge repair (TEER) versus surgical mitral valve repair for degenerative mitral regurgitation (DMR) over the long term. The study aims to:
- Evaluate the effectiveness and safety of TEER versus surgery in patients with DMR over long term.
- Investigate the predictors of left ventricular dysfunction and clinical outcomes using advanced imaging techniques, such as cardiac MRI
- Assess patient-reported recovery and quality of life outcomes using validated tools.
The study focuses on improving care strategies for patients with DMR, particularly those at higher surgical risk, by identifying optimal treatment approaches and predictors of recovery.

Suunnittelun yksityiskohdat
Kohortit ja interventiot
Ryhmä/Kohortti |
|---|
|
Surgical mitral repair
This cohort includes patients who underwent surgical mitral valve repair for severe degenerative mitral regurgitation (DMR).
The intervention involves standard surgical techniques to repair the mitral valve, aiming to restore its physiological function and reduce mitral regurgitation.
|
|
Transcatheter mitral edge-to-edge repair
This cohort includes patients who underwent transcatheter edge-to-edge repair (TEER) for severe degenerative mitral regurgitation (DMR).
The intervention involves a minimally invasive transcatheter procedure using a device to approximate the mitral valve leaflets, reducing regurgitation.
