pulmonary valve knife 肺动脉瓣刀
Sometimes the pulmonary valve is completely obstructed (pulmonary atresia). 有时候肺动脉瓣完全阻塞（肺动脉瓣闭锁）。
On its own, pulmonary valve insufficiency is seldom severe enough to require treatment. 就其本身而言,肺动脉瓣闭锁不全很少严重到需要治疗
Objective:To discuss the surgical treatment of tetralogy of Fallot with absent pulmonary valve (TOF/APV). 目的：探讨法乐四联症合并肺动脉瓣缺如(TOF/APV)的外科治疗方法。
This patient received operation of pulmonary valve replacement, infundibulectomy and ASD closure. 病人接受肺动脉瓣置换手术并漏斗部刮除，及心房中隔缺损修补手术。
The bore of right ventricle and pulmonary artery widned gradually with increasing time in Tibet. The peak velocity of tricuspid valve and pulmonary valve increased obviously. 右心室和肺动脉内径随进藏时间增加呈逐渐增宽趋势,肺动脉瓣、三尖瓣峰值流速明显增快。
In 2 patients with ASD and PS,the systolic pressure across the pulmonary valve decreased from 48mmHg and 54mmHg to 7mmHg and 10mmHg after intervention. 2例合并PS者,跨肺动脉瓣压差由术前48 mmHg、54 mmHg下降到术后7 mm-Hg1、0 mmHg。
Among them,8 patients with pulmonary valvular stenosis,1 patient with mutiple stenosis of pulmonary valve,ring and trunk. 结果:全组无死亡病例,术后合并严重低心排8例,急性肾功能衰竭1例。
Pulmonary valve stenosis is a medical condition in which outflow of blood from the right ventricle of the heart is obstructed at the level of the pulmonic valve. 什么是'肺动脉狭窄-减少了血液供应紧张的肺因为心脏瓣膜的心脏和肺部'?
The right ventricular cineangiogram was done before and immediately following dilation to measure the diameter of pulmonary valve annulus and observe the infundibular spazm. 术前、术后定期行经胸超声心动图检查，估测最大跨肺动脉瓣压力阶差，并观察肺动脉瓣形态及其反流情况。
The bore of right ventricle and pulmonary artery widned gradually with increasing time in Tibet.The peak velocity of tricuspid valve and pulmonary valve increased obviously. 右心室和肺动脉内径随进藏时间增加呈逐渐增宽趋势,肺动脉瓣、三尖瓣峰值流速明显增快。
Background: Percutaneous pulmonary valve implantation was introduced in the year 2000 as a nonsurgical treatment for patients with right ventricular outflow tract dysfunction. 背景：经皮肺动脉瓣置换技术对于右心室流出道功能障碍的患者作为非手术治疗在2000年被引入。
The pulmonary valve (also called the pulmonary semilunar valve) lies at the base of the pulmonary trunk, where it prevents the backflow of ejected blood into the right ventricle. 这些结构可以防止心室瓣的外翻,就像一把强风中雨伞,当心室收缩的时候心室的压力就会增加。
The simple intracar-diac repairment was done in 5 cases,enlargement of right ventricular outflow tractbelow pulmonary valve in 21 cases and enlargement of right ventricular outflowtract across the pulmonary valve ring in 17 cases. 单纯心内修复5例,右室流出道肺动脉瓣下加宽21例,跨肺动脉瓣环加宽17例。
Conclusion Surgical treatment with cardiopulmonary bypass is safer and more effective for some cases of severe pulmonary valve stenosis than percutaneous balloon pulmonary valvuloplasty. 结论体外循环下治疗小儿重度肺动脉瓣狭窄具较高安全性；
Methods 30 TOF patients were divided into group A (pulmonary valves function well) and group B(pulmonary valves exhibit a poor function). 方法30名法洛四联症病人分成两个组,A组病人肺动脉功能发育良好,B组病人肺动脉发育不良。
congenital stenosis of pulmonary valve 先天性肺动脉瓣狭窄
Congenital absence of pulmonary valve 先天性肺动脉瓣缺失
Congenital atresia of pulmonary valve 先天性肺动脉瓣闭锁
Congenital insufficiency of pulmonary valve 先天性肺动脉瓣闭锁不全
