We present a mass-spring model for simulating mitral valve repair.
- class="label">•
The patient-specific model geometry is based on pre-surgical 3D TEE images.

We use a rest-length estimation algorithm for modeling of the tendinous cords.

A comparison with post-surgical 3D TEE images proves the feasibility of our approach.

Our simulation is faster than comparable state-of-the-art finite-element simulations.
