[Pulmonary valvotomy in adults. The double balloon technic--apropos of 2 cases].

Percutaneous double balloon valvotomy was performed in two adult patients with severe non dysplasic pulmonary valvular stenosis. The balloons were introduced through two 14F sheaths placed in the right and left femural veins, the intervention was well tolerated and succeeded with a marked decrease in right ventricular pressure and in pulmonary transvalvular gradient (113 and 147 mmHg to 10 and 12 mmHg respectively). The patients were discharged within 24 hours, without the need of Intensive Care admission. Indications for the procedure and technical aspects are presented, as well as the potential advantages of two balloons over one balloon and surgical valvotomy.
