We performed percutaneous transluminal balloon valvoplasty in a 53-year-old woman with severe valvar pulmonary stenosis. Peak systolic gradient across the pulmonary valve reduced from 112 mm Hg before valvoplasty to 47 mm Hg immediately after dilatation, which further fell to 30 mm Hg six months after valvoplasty with virtual disappearance of gradient at one year follow up. Patients of isolated valvar pulmonary stenosis presenting in late adult life can be adequately and safely treated with balloon valvoplasty, without recourse to surgery with excellent immediate and long-term results.
我们对一名患有严重肺动脉瓣狭窄的53岁女性进行了经皮腔内球囊瓣膜成形术。肺动脉瓣跨瓣收缩期峰值压差从瓣膜成形术前的112毫米汞柱降至扩张后即刻的47毫米汞柱，瓣膜成形术后6个月进一步降至30毫米汞柱，在1年随访时压差几乎消失。成年晚期出现的孤立性肺动脉瓣狭窄患者可通过球囊瓣膜成形术得到充分且安全的治疗，无需进行手术，近期和远期效果均极佳。
