肺动脉瓣关闭不全，多见于肺动脉瓣环扩大和肺动脉高压引起肺动脉主干扩张导致的功能性关闭不全，较少见于特发性肺动脉扩张、马凡氏综合征、肺动脉瓣脱垂，也是法洛四联症根治术后一种常见的远期并发症。肺动脉瓣关闭不全导致右心室扩张、右心功能不全、致死性心律失常等直接影响患者的生存质量和远期生存率。目前主要是治疗原发病及其所致的右心衰竭、心律失常等；对于引起右心室容量负荷进行性加重及反复右心衰竭的重度器质性肺动脉瓣关闭不全患者需要进行肺动脉瓣置换术。经皮肺动脉瓣置换术随着瓣膜、支架、传送系统、手术路径等改良，取得了一定进展，现就肺动脉瓣关闭不全经皮肺动脉瓣置换术进展做一综述。

Pulmonary valve regurgitation is common seen in pulmonary valve ring expansion and pulmonary hypertension and less seen in idiopathic pulmonary expansion, Marfan syndrome, and pulmonary valve prolapse.This is also a common long-term complications after tet-ralogy of Fallot radical correction.Pulmonary valve regurgitation may lead to right ventricular dilatation, right ventricular dysfunction and fatal arrhythmias.All of this have direct impact on the quality of life and long-term survival in patients.At present, the treatment of the primary disease and right heart failure and arrhythmia is important.But the patients with right ventricular volume overload,progressive right heart fail-ure and severe organic pulmonary valve regurgitation need pulmonary valve replacement surgery.Percutaneous pulmonary valve replacement surgery has been relatively mature, and the technology has made great progress with improved valves, stents, delivery systems and surgical path.The progress of percutaneous pulmonary valve replacement surgery is reviewed in this article.
