Physically-coherent Extraction of Mitral Valve Chordae

International audienceSurgical repair of the mitral valve is challenging as it is difficult to anticipate the outcome of any modification of the valve structure, particularly the tendinous chordae. Recent works on computer-based models of mitral valve behavior rely on manual extraction of the complex valve geometry, which is tedious and requires a high level of expertise. On the contrary, we propose a method to segment the chordae with little human supervision. The effectiveness of our approach is shown by comparing our segmen-tation to the manual delineation via the simulation of the closed valve state
