Abstract: Percutaneous balloon pulmonary valvuloplasty (PBPV) has become the first choice for the treatment of pulmonary valve stenosis (PS). PBPV is used not only in the independent way to relieve Milo-Ⅰ amp; Ⅱ type of PS as an alteration of surgery, but also in the combination way with surgical treatment to some multiple or complex congenital heart defect,where it plays a part as a pre-operative appeasement or a co-operative procedure, even a supplementary expedience to some failed surgery post-operatively. In this paper, the anatomic classification of PS, the usage of ultrasounic examination, the indication and contraindication, the method and skill during operation, and the effect evaluation of PBPV are reviewed.
