AB  - PURPOSE: To study the immediate clinical, echocardiographic and hemodynamic 
      results of 200 patients who underwent percutaneous mitral balloon valvotomy (PMV) 
      with double balloon technique. METHODS: Two hundred patients were submitted to 
      PVM for treatment of congestive heart failure secondary to severe mitral 
      stenosis, between August 1987 to July 1991. Their mean age was 35.2 years, and 
      86.5% were female patients: 81% of them was in functional class, New York Heart 
      Association (NYHA) III or IV; 4% was in atrial fibrilation and 4% had previous 
      surgical commissurotomy. RESULTS: PMV was successfully performed in 89% of the 
      patients. The mitral valve area, by pressure half time method, increased from 
      0.91 +/- 0.27 to 2.10 +/- 0.47 cm2, p < 0.001; the mean mitral gradient decreased 
      from 20.86 +/- 6.16 to 4.26 +/- 3.13 mmHg, p < 0.001; the left atrium and mean 
      pulmonary artery pressure decreased from 22.3 +/- 7.1 to 11.9 +/- 8.3 and 36.47 
      +/- 12.93 to 24.56 +/- 9.98 mmHg, p < 0.001, respectively. Complications related 
      to transeptal technique occurred in 12 patients, which resulted in cardiac 
      tamponade in 5 and death in 1. In 19 patients the punction of the atrial septum 
      could not be performed. Mitral regurgitation (MR) immediately after PMV appeared 
      1+ or more grade in 50 patients, increased in 8 patients and remained unchanged 
      in 11 patients. Ten patients needed mitral valve replacement in the first 48h 
      after PMV, for treatment of severe MR. CONCLUSIONS: PMV produces excellent 
      immediate results and can be considered an alternative to surgery for the relief 
      of mitral stenosis.
