Abstract		Background. Closed and open mitral commissurotomy and valve replacement used to be the only methods of treatment for the patients with severe mitral stenosis. Recently catheter balloon valvuloplasty has been performed in these patients. Although its clinical application as now widely adopted, its indications and potential complications are not yet thornughly defined. In our patient group, valvuloplasty was performed by double balloon technique and single balloon technique. Materials and methods. 26 patients with severe mitral stenosis underwent percutaneous mitral valvuloplasty. Retrograde transarterial approach with double balloon technique was performed in 11 patients and single balloon technique with transseptal approach in 15. Hemodynamic parameters (PCW, MG, PT and CO) and echocardiographyc (MVA) were compared before and after the procedure. Statistical analysis was made. The long-term observation of clinical state and measurements were performed in 15 patients. Results. Valvuloplasty resulted in significant decrease in PCW from 24.3 +- 5.2 mmHg to 14.5 +- 4.2 mmHg (p less th. 0.0001), mitral gradient (MG) from 15.7 = 4.1 mmHg to 6.9 +- 3.1 mmHg (p less th. 0.0001). Mitral valve area (MVA) increased from 1.00-0.02cm to 1.80.03 cm2 (p less th. 0.0001). In two cases the procedure was unsuccessful. Mitral regurgitation occurred in one patient with calcific valve and the other developed pulmonary oedema. Mitral replacement was necessary. Follow-up of 15 patients revealed slight reduction of MVA in all patients. In 3 patients, replacement of mitral valve was performed after 16 months. Twelve patients are still in good haemodynamic and clinical conditions (after 36 months). Conclusions. Valvuloplasty achieves immediate hemodynamic and clinical improvement. Inproperly selected patients, the longterm results are good. Both methods are successful as to the hemodynamic results and complication rate.(trunc.)
