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.
对两名患有严重非发育异常性肺动脉瓣狭窄的成年患者进行了经皮双球囊瓣膜切开术。通过分别置于右股静脉和左股静脉的两个14F鞘管插入球囊，干预耐受性良好且成功，右心室压力和肺动脉跨瓣压差显著降低（分别从113和147 mmHg降至10和12 mmHg）。患者在24小时内出院，无需入住重症监护病房。本文介绍了该手术的适应症、技术要点，以及双球囊相对于单球囊和外科瓣膜切开术的潜在优势。
