经皮球囊肺动脉瓣成形术治疗效果和远期随访

The immediate results and long-term follow-up after percutaneous balloon pulmonary valvulo-plasty

为评价经皮球囊肺动脉瓣成形术治疗单纯性肺动脉瓣狭窄患儿的近期和远期效果及影响疗效的因素 ,对经皮球囊肺动脉瓣成形术治疗的167例单纯性肺动脉瓣狭窄患儿进行随访 ,随访时间为术后 (0.6±0.3)年～(8.6±1.5)年 ,以超声心动图测得的右心室与肺动脉之间的跨瓣压差为随访指标。结果显示 ,167例中163例获得成功(成功率为97.6%) ,获成功者术前跨瓣压差为 (87.6±37.4)mmHg,术后立即降为 (35.9±18.5)mmHg,术后2年内跨瓣压差进一步下降 ,5年和8年随访结果表明其远期效果稳定。提示经皮球囊肺动脉瓣成形术安全可靠 ,术后即刻和远期效果好 。

To evaluate the immediate and long-term results of patients after percutaneous balloon pul-monary valvuloplasty treatment of isolated valvar pulmonary stenosis,and to determine its influencing fac-tors,167patients with isolated valvar pulmonary stenosis underwent percutaneous balloon pulmonary valvu-loplasty were involved in our study.A follow-up for0.6±0.3to8.6±1.5years was obtained,and transvalvular pressure gradient from the right ventricle to the pulmonary artery was measured with Doppler echocardiography as the index of follow-up.The results showed that percutaneous balloon pulmonary valvu-loplasty was successful in163of167patients,and overall success rate was97.6%.After pulmonary valvulo-plasty,the transvalvular pressure gradient fell immediately from87.6±37.4mmHg to35.9±18.5mmHg.During two years follow-up,transvalvular gradient decreased continuously.The children still have been keeping in stable condition in long term following-up for five and eight years.Pulmonary balloon valvuloplasty is a safe and an effective treatment with excellent immediate and long-term results,no serious complications can be noted in any patient.
