title: [Direct observation of the effect of mitral valvuloplasty on beating heart].
abstract: OBJECTIVE
  To summarize the method and experience of direct observation of the effect of mitral valvuloplasty on beating heart.
  
  
  METHODS
  Twelve patients with mitral regurgitation underwent mitral valvuloplasty. When the heart was beating slowly before releasing the aorta, the morphology and function of the mitral valve were evaluated by direct observation. If the results were unsatisfactory, further techniques were used to reach the goal.
  
  
  RESULTS
  During the operation 2 patients needed further techniques to make the mitral valve work well. No operative death and only 1 complication (low cardiac output syndrome) occurred. After 1 month follow-up later, mild regurgitation was found in 5 patients, moderate regurgitation in 1 and no obvious regurgitation in 6.
  
  
  CONCLUSIONS
  Evaluating the effect of mitral valvuloplasty by direct observation on beating heart is practicable.
