We describe a case of percutaneous balloon valvoplasty of a stenotic Ionescu-Shiley mitral bioprosthesis with the help of an original emboli-protecting device. The procedure reduced diastolic gradient from 29 to 9 mmHg. The calculated area of the orifice increased from 0.7 to 1.7 cm2. At 10 months follow-up examination there was no change of hemodynamic parameters.
