Percutaneous balloon valvuloplasty(PBV) was successfully performed in 8 mitral stenosis patients for recent 3 months, Five patients have aortic insufficiencies also and two patients have mitral regurgitations below grade II/IV. All patients showed sinus rhythm on EKG and had no mitral valvuar calcification on echocardiography and fluoroscopy. PBV resulted in an increase in mitral valve area from 1.22$pm$0.22 to 2.57$pm$ 0.86 cm2 a decrease in mean left atrial pressure from 23.4$pm$9.4 to 6.8$pm$3.1 mmHg. There were no significant compli-cations except 2 cases of newly appeared and mildly aggrevated mitral regurgitation. We cations except 2 cases of newly appeared and mildly aggrevated mitral regurgitation. We believe that PBV will become a treatment modality of choice replacing surgical commissu-rotomy or valve replacement in a group of mitral stenosis patients. because of its effectiveness and safety.
