Latest research on mitral regurgitation
- #VisualAbstract Transcatheter Edge-to-Edge Repair was Non-inferior to Mitral-Valve Surgery for Secondary Mitral Regurgitation
- Use of fluoroquinolones and may increase the risk of aortic and mitral regurgitation
- #VisualAbstract: Transcatheter repair of mitral regurgitation secondary to cardiomyopathy is safe and effective
- Transcatheter repair of mitral regurgitation secondary to cardiomyopathy is safe and effective
- Transcatheter mitral valve repair may be a reasonable option in high-surgical-risk patients with degenerative mitral regurgitation
