[Percutaneous mitral commissurotomy by a domestic balloon catheter in 215 patients and a follow-up study of 41 cases].
Between June, 1987 and June 1990, percutaneous balloon catheter mitral commissurotomy (PBMC) was performed in 215 patients (mean age 37.1 +/- 10.1 years) with rheumatic mitral stenosis by domestic balloon catheter and were successful in 213 patients (99%). After PBMC, there was a significant improvement in mitral gradient (2.58 +/- 0.93 kPa to 0.66 +/- 0.31 kPa, P less than 0.001), mean left atrial pressure (3.18 +/- 0.94 kPa to 1.26 +/- 0.55 kPa, P less than 0.001), mitral valve area (1.14 +/- 0.22 cm2 to 2.27 +/- 0.42 cm2, P less than 0.001) and left atrial dimension (46 +/- 5 mm to 36 +/- 4 mm, P less than 0.001). Severe mitral regurgitation was noted in two patients (0.9%) and pericardial tamponade in one patient (0.5%). No death was occurred. 41 patients from the first 160 ones were followed up for a mean of 25 +/- 6 months (12-36 months). Mitral valve area remained stable in all but one with restenosis. In addition, the experience on prevention and cure for complications of PBMC were discussed.
