Percutaneous mitral ballon vavuloplasty(PMV) using the double-ballon technique was performal in a 48 year old female patient with recurrent mitral stenosis 16 years after surgical open mitral commissurotomy. PMV resulted in an increase in mitral valve area by Gorlin's method from 0.9 to 2.2 cm2, a decrease in mean mitral diastolic pressure gradient from 30 to 17 mmHg, and an increase in cardiac output from 4.7 to 5.5 L/min. There was no evidene of significant left to right shunt through the atrial septal punture site PMV. After PMV minimal grade 1 mitral regurgutation developed. Mitral ballon valvuloplasty can be performed effectively and safely in selected patients with restenosis after surgical commissurotomy.
