Balloon valvuloplasty was used to treat congenital pulmonary valve stenosis in 13 patients, 11 with isolated pulmonary stenosis, one associated with complex univentricular heart and tricuspid atresia, and one associated with tetralogy of Fallot. A balloon catheter was introduced through the pulmonary valve over a guidewire positioned in the distal pulmonary artery and inflated for 15 seconds on two or three occasions to 3 to 5 atmospheres and rapidly deflated. Marked improvement in pressure gradients was achieved in eight of the 11 patients with isolated pulmonary valve stenosis and symptoms disappeared in the only patient in this group who was symptomatic. The two patients with complex congenital malformations improved clinically. The procedure was without complication and satisfactory results have been maintained from two to twelve months later. The procedure offers effective treatment. We believe that pulmonary balloon valvuloplasty should be the initial treatment for isolated severe and moderate pulmonary valve stenosis.
采用球囊瓣膜成形术治疗13例先天性肺动脉瓣狭窄患者，其中11例为单纯肺动脉狭窄，1例合并复杂单心室心脏和三尖瓣闭锁，1例合并法洛四联症。通过位于肺动脉远端的导丝将球囊导管经肺动脉瓣插入，并两到三次充气至3至5个大气压，持续15秒，然后迅速放气。11例单纯肺动脉瓣狭窄患者中有8例压力阶差明显改善，该组中唯一有症状的患者症状消失。2例合并复杂先天性畸形的患者临床症状改善。该手术无并发症，术后两到十二个月效果满意。该手术提供了有效的治疗方法。我们认为，肺动脉球囊瓣膜成形术应作为单纯中重度肺动脉瓣狭窄的初始治疗方法。
