Mitral valve repair: Residual MR matters
In the early days of transcatheter mitral valve repair, the goal was a successful procedure that reduced mitral regurgitation (MR) to less than 3+; residual MR grade 2+ was considered acceptable.1,2
Compelling new data on more than 5400 patients show that residual MR grades 0–1+ are significantly associated with superior patient outcomes when compared with residual MR 2+, including reduced mortality and rehospitalisation.3–8
Lower MR grades are
within your clasp
More Opportunity, Lower MR Grades
A unique central spacer is designed to block
more jet and minimise MR
Independent Leaflet Grasping
Independent actuation and distinct clasp
design allow leaflet capture precision while
respecting native anatomy
Device Elongation
Device elongation feature optimises subvalvular manoeuvrability when you need it

Study design & baseline parameters1
| Study Design: Multicenter, multinational, prospective, single-arm study | |
|---|---|
| Total patients: 109 | FMR: 67% | DMR: 33% |
| NYHA Class III/IV: 57.4% | MR severity ≥3+: 100% |
| Mean age: 75.5 years | PISA EROA: 0.38 ± 0.16 cm2 |
| Regurgitant volume: 57.2 ± 20.6 ml | Mean vena contracta width, A-P: 6.3 ± 1.4 mm |
Significant MR reduction: 82% of patients with MR 0-1+ at 1 year
High Survival Rate at 12 months
