title: Predictors of surgery after percutaneous mitral valvuloplasty.
abstract: BACKGROUND
  Percutaneous mitral valvuloplasty (PMV) is a minimally invasive treatment option for selected patients with mitral stenosis (MS). In general, the procedure is well-tolerated with a high success rate. However, relatively little is known about the predictors of surgical intervention after PMV.
  
  
  METHODS
  A retrospective analysis was performed on 243 patients undergoing PMV at a single institution over a 14 year period.
  
  
  RESULTS
  Fifty (21%) of 243 patients, comprising 44 women and 6 men and aged 55 +/- 14 years, underwent cardiac surgery at a median interval of 6 months (range, 0 to 130) after PMV. Nine (18%) underwent a procedure within 15 days, and 41 (82%) had a procedure more than 15 days after the valvuloplasty. After PMV, surgery-free survival was 85% at 1 year, 83% at 2 years, 81% at 3 years, 80% at 4 years, and 80% at 5 years.
  
  
  CONCLUSIONS
  The need for surgery after PMV is not uncommon. Independent predictors of surgery after PMV included severity of mitral regurgitation (p < 0.003) and a higher echo score (p < 0.039).
