The SimuForm ring is elevating mitral repair — its flexible anterior part accommodates anterior motion, while the semi-rigid posterior part enables remodeling.

SimuForm rings are not fixed into a saddle shape — they are flattened to an "O" shape to accommodate diastolic filing dynamics.
Results from a single-center, retrospective analysis show that the SimuForm platform7:
Cumulative incidence of reoperation
Degree of mitral valve regurgitation
Watch Professor Lange's presentation on the SimuForm platform's clinical performance at the EACTS 2021 annual meeting.
Place sutures along the entire flexible ring while fully accessing anatomy.
Easily identify the two cut towers on the holder, which enables quick release of the ring.
Allows for low-force, single-cut release, and remains securely attached during suturing.
Provides visual reference of annular plane when performing chordal repair.
