title: [Clinical analysis of robotic mitral valve repair].
abstract: OBJECTIVE
  To determine the safety and efficacy of robotic mitral valve repair using da Vinci S Surgical system. Method From January 2007 to April 2011, over 400 cases of robotic cardiac surgery have been performed, in which 60 patients with isolated mitral valve insufficiency underwent robotic mitral valve repair, including 42 male and 18 female patients with a mean age of (44 ± 13) years (ranging from 14 to 70 years). Forty-eight patients were in NYHA class I-II and 12 patients in class III. Fourteen patients were concomitant with atrial fibrillation. Surgery approach was achieved through 4 right chest ports with femoral perfusion and Chitwood aortic occlusion. Antegrade cold blood cardioplegia was administered directly via chest for myocardial protection. The transesophageal echocardiography was used intraoperatively to estimate the surgical results.
  
  
  RESULTS
  All patients had successful valve repair including quadrangular resections, sliding plasties and chordal replacement. There was no conversion to median sternotomy. The mean cardiopulmonary bypass and arrested heart time were (132 ± 30) min and (88 ± 22) min. One patient had hemolysis after operation, and required mitral valve replacement. Echocardiographic follow-up revealed trace to mild regurgitation in 2 patients with a mean of (16 ± 9) months.
  
  
  CONCLUSIONS
  Robotic mitral valve repair is safe and efficacious in the patients with isolated mitral valve insufficiency.
