Mitral Valve Transcatheter Edge-to-Edge Repair: 1-Year Outcomes From the MiCLASP Study
Authors' conclusion
One-year outcomes of this large cohort from the MiCLASP study demonstrate continued safety and effectiveness of M-TEER with the PASCAL system in a post-market setting.
Study context
- Population
- Patients with symptomatic, clinically significant mitral regurgitation (MR)59% functional MR, 30% degenerative MR
- Participants

- Outcome
- Safety: 30-day composite major adverse event rate (clinical events committee-adjudicated); effectiveness: MR severity at discharge vs baseline (echocardiographic core laboratory)
- Follow-up
- 30 days; discharge
