肺动脉瓣球囊成形术的临床应用

CLINICAL APPLICATION OF BALLOON VALVULOPLASTY FOR CONGENITAL PULMONARY VALVE STENOSIS

用肺动脉瓣球囊成形术治疗１７例先天性肺动脉瓣狭窄患者。结果表明，术后平均右心室收缩压由１３．０５±５．４９ｋＰａ降至４．８８±１．８４ｋＰａ（Ｐ＜０．０１）；收缩期最大跨肺动脉瓣压由１０．３９±５．７５ｋＰａ降至２．３３±１．６９ｋＰａ（Ｐ＜０．０１）。４例术后１７～３２月经导管复查，基本维持球囊成形术后的状态。

Seventeen patients with congenital pulmonary valve stenosis were treated by balloonvalvuloplasty,The procedures were well tolerated by the patients and the results were suc-cessful.After the operation,the mean right ventricular systolic pressure was decreased from13.05±5.84kPa to 4.88± 1.84kPa(P<0. 01)and the mean pulmonary valvular peak-to-peak systolic gradient was decreased from 10.39±5.75kPa to 2.33±1.69kPa(P<0.01) Four patients were followed up for 17 to 32 months after the operation,the reassessmentresults showed that the therapeutic effects were well maintained.Thus,balloon valvuloplas-ty is a safe and effective method for the treatment of congenital pulmonary valve stenosis.
