Pulmonary incompetence
...少见为特发性或马凡综合征的肺动脉扩张。肺动脉瓣原发性损害所致者较少见，如感染性心内膜炎、肺动脉瓣狭窄或法乐四联征术后、类癌综合征和风心病。肺动脉瓣关闭不全(pulmonary incompetence)引起右室容量过度负荷，如无肺动脉高压，可耐受多年；如有肺动脉高压，则加速右室衰竭发生。

结果示右房径路组术后右心室收缩功能优于右室径路组，术后心律失常及肺动脉瓣关闭不全发生率明显为低。
Results:the contractile function of right ventricle was better in transatrial approach group. The incidences of arrhythmia and pulmonary regurgitation were lower.

结论二尖瓣置换术后远期三尖瓣功能性关闭不全与三尖瓣环扩大、右心功能损害和严重肺动脉高压有关，三尖瓣环扩大是其重要的原因。
Conclusion tricuspid annular dilatation, right heart impairment and severe pulmonary hypertension are responsible for the development of late tricuspid regurgitation after mitral valve replacement.

肺动脉瓣关闭不全
肺动脉瓣关闭不全（pulmonary incompetence），是指肺动脉瓣受到器质性或功能性损害，致右室舒张时血液从肺动脉通过肺动脉瓣反流入右心室造成的血流动力学障碍。肺动脉瓣关闭不全常伴发于其他心血管疾病，尤其是肺动脉高压者更易发生，单独的先天性肺动脉瓣关闭不全很少见。
