Intraoperative measurements on the mitral apparatus using optical tracking: a feasibility study |
Abstract | ||
|---|---|---|
Mitral valve reconstruction is a widespread surgical method to repair incompetent mitral valves. During reconstructive surgery the judgement of mitral valve geometry and subvalvular apparatus is mandatory in order to choose for the appropriate repair strategy. To date, intraoperative analysis of mitral valve is merely based on visual assessment and inaccurate sizer devices, which do not allow for any accurate and standardized measurement of the complex three-dimensional anatomy. We propose a new intraoperative computer-assisted method for mitral valve measurements using a pointing instrument together with an optical tracking system. Sixteen anatomical points were defined on the mitral apparatus. The feasibility and the reproducibility of the measurements have been tested on a rapid prototyping (RP) heart model and a freshly exercised porcine heart. Four heart surgeons repeated the measurements three times on each heart. Morphologically important distances between the measured points are calculated. We achieved an interexpert variability mean of 2.28 +/- 1.13 mm for the 3D-printed heart and 2.45 +/- 0.75 mm for the porcine heart. The overall time to perform a complete measurement is 1-2 minutes, which makes the method viable for virtual annuloplasty during an intervention. |
