Robotic Totally Endoscopic Repair of Barlow's Mitral Valve

This video shows a mitral valve repair for a 52-year-old woman with severe, symptomatic mitral regurgitation secondary to a Barlow's valve. Her left ventricle and left atrium are both enlarged. What is unique is that the procedure was performed with what the authors believe are the smallest chest incisions used by any surgical team in the world to date for mitral valve repair, a 12 mm working port and four 8 mm robotic ports. Two things made this feasible: a completely catheter-based approach to myocardial protection and cardiopulmonary bypass, and the unique dexterity of the robotic instruments and camera.
