Mitral transcatheter edge-to-edge repair vs. isolated mitral surgery for severe mitral regurgitation: a French nationwide study
Main finding · CV deathResult — go to the resultHazard ratio 0.685 95% CI 0.563–0.832Authors' conclusion
Our results suggest that TEER for severe mitral regurgitation was associated with lower cardiovascular mortality than mitral surgery at long-term follow-up. Pacemaker implantation and stroke were less frequently observed after TEER.

Further findings
| Outcome | HR (95% CI) | P value | |
|---|---|---|---|
| Non-CV death · 3-year follow-upMore frequent after TEER | 1.562 (1.238–1.971) | P = 0.0002 | |
| All-cause death · 3-year follow-up | 0.967 (0.835–1.118) | P = 0.65 | |
| 0.512Hazard ratio (log scale) |
Pacemaker implantation, stroke · 3-year follow-up
- Significantly lower incidence with TEER
Recurrent pulmonary oedema, cardiac arrest · 3-year follow-up
- More frequent after TEER
Endocarditis, major bleeding, AF, MI · 3-year follow-up
- No significant differences between the two groups
