title: [Surgical intervention in patients undergoing a procedure for mitral valvoplasty by balloon catheterization].
abstract: OBJECTIVE
  To study the characteristics of patients undergoing catheter-balloon mitral valvoplasty (CBVM) procedure who needed surgical intervention after CBMV.
  
  
  METHODS
  One hundred and five patients submitted a CBMV were divided in to Group I (GI) of eighteen surgical patients and Group II (GII) of eighty-seven non-surgical patients. The following parameters were analyzed. 1) age; 2) sex; 3) mitral valve area (MVA) and mean transvalvular gradient (G) by echodopplercardiography (2D); 4) Character of CBMV; 6) Relation of time between CBMV and Surgery with surgical indication; 7) Surgical findings; 8) Surgical procedure and 9) Post-operative evolution.
  
  
  RESULTS
  Mean age of 34 (17-56) years old in GI and 33 (15-69) years old in GII; 2) Similar distribution of men and women in GI and GII; 3) Similar MVA and G in GI and GII; 4) 100% of elective character in GI and 94% in GII; 5) Transseptal via in 17 (94%) of GI and 87 (83%) of GII, retrograde arterial via in 1 (5.5%) of GI and in another (1%) of GII; 6) immediate: cardiac tamponade (28%); until 30 days: unsuccessful CBMV (39%); mitral insufficiency (MI) post-CBMV (11%), cardiac tamponade (5.5%), between 30 and 60 days: MI post-CBMV (22%), Mitral restenosis post-CBVM (5.5%); 7) Mitral stenosis (72%), MI post-CBVM (22%), hemopericardium (6%); 8) Mitral Commissurotomy (7), Mitral bioprosthesis implant (5), Commissurotomy plus Atrioseptoplasty (1), Mitral plasty (1), Pericardium drainage (1); 9) One (5.5%) death in immediate post-operative of the MI correction, 17 (94%) in functional class I/II (NYHA) 14.3 (8-27) months after surgery.
  
  
  CONCLUSIONS
  Age, Sex, VMA G and Urgency character were not discriminative factors in the formation of GI and GII. The procedures for CBVM didn't interfere with post-operative prognosis.
