Pulmonic valvuloplasty is a well-established method for the treatment of valvular pulmonic stenosis in people and dogs. In dogs, pulmonic valvuloplasty has been restricted to a single balloon; however, the simultaneous use of two balloons is common in pediatric cardiology. The use of two balloons provides an alternative to the use of a single large balloon in small dogs with a pulmonic anulus size that requires a large dilation catheter and large diameter introducer. Moreover, double balloon valvuloplasty permits dilation in large dogs with large pulmonic anulus sizes for which standard dilation catheters are not available. This report outlines the materials required, describes the technique, gives the advantages and disadvantages encountered when performing percutaneous double balloon valvuloplasty and provides some 'tips' for a successful outcome.
肺动脉瓣成形术是治疗人和犬类瓣膜性肺动脉狭窄的一种成熟方法。在犬类中，肺动脉瓣成形术一直局限于使用单个球囊；然而，在儿科心脏病学中同时使用两个球囊很常见。对于肺动脉瓣环尺寸较小、需要使用大尺寸扩张导管和大直径导入器的小型犬，使用两个球囊提供了一种替代使用单个大球囊的方法。此外，双球囊瓣膜成形术允许对肺动脉瓣环尺寸较大、没有标准扩张导管可用的大型犬进行扩张。本报告概述了所需材料，描述了技术，介绍了进行经皮双球囊瓣膜成形术时遇到的优缺点，并提供了一些取得成功结果的“小贴士”。
