Key result
An interactive surgical simulator for mitral valve repair achieved sub-millimeter accuracy and was successfully used by a cardiac surgeon to repair three virtual pathological valves.
An interactive surgical simulator for mitral valve repair achieved sub-millimeter accuracy and was successfully used to virtually repair pathological valves, potentially aiding surgical planning and training.
Does not support clinical adoption; leaves open validation for mitral valve training and planning.
Surgical repair of the mitral valve is a difficult procedure that is often avoided in favor of less effective valve replacement because of the associated technical challenges facing non-expert surgeons. In the interest of increasing the rate of valve repair, an accurate, interactive surgical simulator for mitral valve repair was developed. With a haptic interface, users can interact with a mechanical model during simulation to aid in the development of a surgical plan and then virtually implement the procedure to assess its efficacy. Sub-millimeter accuracy was achieved in a validation study, and the system was successfully used by a cardiac surgeon to repair three virtual pathological valves.

Tenenholtz et al. (2011) studied Mitral valve pathology. Interactive, patient-specific surgical simulator was evaluated on Simulator accuracy and successful virtual repair. An interactive surgical simulator for mitral valve repair achieved sub-millimeter accuracy and was successfully used by a cardiac surgeon to repair three virtual pathological valves.
