1 Evaluation of a new left atrial retractor for minimally invasive mitral valve surgery 
Olivier Jegaden, MD, Thomas Sassard, MD, Abdel Shafy, MD, Mouhcine Madani, MD, Fadi Farhat, MD, PhD  The Journal of Thoracic and Cardiovascular Surgery  Volume 141, Issue 1, Pages (January 2011) DOI: /j.jtcvs Copyright © 2011 The American Association for Thoracic Surgery Terms and Conditions

2 Figure 1 The MitraXs (St Jude Medical Inc, Minneapolis, Minn) is a self-supporting atrial retractor. A, In deployed position with 1 overmoduled pivoting rivet that makes its conical shape self-expanding and auto-adjusting. B, In rolled and compressed position, with triangular tab protruding out of the cylinder, which makes introduction into the left atrium easy.

3 Figure 2 Intraoperative view. A, The mitral valve is nicely exposed without distortion, allowing easy and accurate analysis of the lesion. The left atrial muscle is homogeneously unfolded, providing space for suturing. B, The mitral valve is visualized in its entirety with a large working space, making en bloc valve resection possible. Note the asanguineous operative field with the vent back. The MitraXs device may prevent tissue fragments from falling into the pulmonary veins.

4 Figure 3 Intraoperative view. A, The MitraXs device is voluntarily centered on the posterior leaflet to make sliding plasty easier. Note the occluded area on anterior annulus that is accessible by sliding and repositioning. B, The MitraXs device is voluntarily pushed inside the mitral annulus to improve the exposure of papillary muscles for artificial chordae implantation.
