[Totally robotic mitral valve surgery in 60 cases].

摘要

OBJECTIVE: To evaluate the safety and efficacy of robotic mitral valve surgery using da Vinci S system. METHODS: We conducted a retrospective review of 60 robotic mitral surgeries from March 2007 to December 2010. Of the 60 patients, 44 underwent mitral valve repair and 16 received mitral valve replacement. The surgical approach was through 4 right chest ports with femoral and internal jugular vein cannulations. Transesophageal echocardiography was used intraoperatively to estimate the surgical results. RESULTS: None of the cases required a conversion to a median sternotomy. The mean cardiopulmonary bypass and cardiac arrest time was 132.2∓29.6 min and 88.1∓22.3 min for robotic mitral valve repair, and was 137.1∓21.9 min and 99.3∓17.4 min for robotic mitral valve replacement. Echocardiographic follow-up of all the patients revealed 3 cases of slight regurgitation in mitral valve repair group. CONCLUSION: In selected patients with mitral valve disease, robotic mitral surgery can be performed safely.
