title: [Clinical experience of 60 patients underwent three-dimensional video assisted thoracoscopic mitral valvuloplasty].
abstract: OBJECTIVE
  To summarize the clinical experience of 60 patients underwent three-dimensional video assisted thoracoscopic mitral valvuloplasty.
  
  
  METHODS
  Sixty patients were enrolled retrospectively from March 2014 to January 2016 in Department of Cardiacvascular Surgery, Guangdong Cardiovascular Institute. They underwent three-dimensional video assisted thoracoscopic mitral valvuloplasty. There were 37 male and 23 female patients. The range of age was 15 to 78 years (the median age was 47 years). The techniques of mitral valvuloplasty included chordae tendineae transplantation (53 patients), annuloplasty (58 patients), posterior leaflet resection (13 patients), anterior leaflet resection (2 patients), commissure resection (1 patient). Their information from charts were collected. The follow-up time was lasting 3 to 25 months by telephone or outpatient department interview. The data was analyzed via paired t test or Wilcoxon signed-rank test.
  
  
  RESULTS
  Conversions to mitral valve replacement were performed for two patients. No patients underwent thoracotomy. The operation time was (213±37) minutes, cardiopulmonary bypass time was (129±31) minutes, aortic cross clamping time was (81±21) minutes. Postoperative hospital stay was (7±3) days. During follow-up period, there were no re-operation and no death. Mitral regurgitation level and New York Heart Association class were both improved (Z=-6.286, P=0.000, Z=-6.237, P=0.000), respectively. Besides, there was also no new atrial fibrillation patients.
  
  
  CONCLUSIONS
  Not only does three-dimensional video assisted thoracoscopic mitral valvuloplasty maintain the advantages of 2-Dimensional thoracoscopy, but also have the similar view of median thoracotomy. This technique showed promising clinical value in the future.
