title: [Minimally invasive video-assisted operations for heart disease].
abstract: BACKGROUND
  Minimally invasive surgical access for the treatment of mitral and tricuspid valves has become an alternative method to the conventional approach via median sternotomy. The aim of this paper is to evaluate our experience and results with minimally invasive approach in cardiac surgery at our institution.
  
  
  METHODS
  A total of 52 patients underwent minimally invasive cardiac surgery between November 2011 and March 2013. Right lateral minithoracotomy and femoral vessels cannulation for cardiopulmonary bypass was used. Follow-up data was collected in a prospective database and analysed retrospectively.
  
  
  RESULTS
  The mean age of patients was 60.9 ± 11.6 years (female patients accounted for 63.5%). The procedures performed included mitral valve repair in 44 (85%) patients and tricuspid valve repair in 25 (48%). Atrial septal defect closure was performed in 8 (15%) patients and cryoablation of atrial fibrillation in 26 (50%) patients. There were 75% combined procedures. The median duration of the operation was 235 (155-315) minutes. The median length of cardiopulmonary bypass and crossclamp time was 139 (89-225) and 92 (51-168) minutes, respectively. The median duration of postoperative hospital stay was 12.5 (6-34) days. Hospital and 30-day mortality was 0%. At follow-up (121.3 ± 32.72 days), two patients (3.8%) required reoperation (1 for right haemothorax, 1 for aortic valve insufficiency).
  
  
  CONCLUSIONS
  Minimally invasive access has been adopted as a routine method for the therapy of valve disease. The minithoracotomy approach is a safe and feasible technique with comparable mortality and in-hospital morbidity.
