Abstract: Objective To evaluate the efficacy and safety of the improved percutaneous balloon mitral valvuloplasty (PBMV) in elderly patients with mitral stenosis. Methods Elderly patients with severe mitral stenosis received an improved PBMV which included a modified way of atrial septal puncture and technique across the mitral valve. The left atrial pressrue (LAP), mean pulmonary pressure (MPA), mean gradient across the mitral value (MPG) and mitral valve area (MVA) were recorded and compared before and after the operation. Long term follow up were made. Results After operation, the LAP decreased [(25.3±6.7) mm Hg vs.(16.4±5.8) mm Hg,1 mm Hg=0.133 Kpa], MPG decreased [(17.6±6.7) mm Hg vs.(6.8±2.9) mm Hg], MPA decreased [(38.6±12.1) mm Hg vs. (29.2±9.8) mm Hg], MVA increased [(1.05±0.22)cm2 vs.(1.61±0.38)cm2] and the New York heart association heart function classification improved. The follow-up result showed that the effect of PBMV was constant. Conclusions Improved PBMV may be an effective and safe measure for patients with mitral stenosis.
