您要查找的是不是:
- pulmonary valve gradient 肺動脈瓣(壓力)階差
- Sometimes the pulmonary valve is completely obstructed (pulmonary atresia). 有時候肺動脈瓣完全阻塞(肺動脈瓣閉鎖)。
- On its own, pulmonary valve insufficiency is seldom severe enough to require treatment. 就其本身而言,肺動脈瓣閉鎖不全很少嚴重到需要治療
- Objective:To discuss the surgical treatment of tetralogy of Fallot with absent pulmonary valve (TOF/APV). 目的:探討法樂四聯症合併肺動脈瓣缺如(TOF/APV)的外科治療方法。
- This patient received operation of pulmonary valve replacement, infundibulectomy and ASD closure. 病人接受肺動脈瓣置換手術並漏斗部刮除,及心房中隔缺損修補手術。
- 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. 右心室和肺動脈內徑隨進藏時間增加呈逐漸增寬趨勢,肺動脈瓣、三尖瓣峰值流速明顯增快。
- 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例合併PS者,跨肺動脈瓣壓差由術前48 mmHg、54 mmHg下降到術后7 mm-Hg1、0 mmHg。
- Among them,8 patients with pulmonary valvular stenosis,1 patient with mutiple stenosis of pulmonary valve,ring and trunk. 結果:全組無死亡病例,術后合併嚴重低心排8例,急性腎功能衰竭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. 什麼是'肺動脈狹窄-減少了血液供應緊張的肺因為心臟瓣膜的心臟和肺部'?
- The right ventricular cineangiogram was done before and immediately following dilation to measure the diameter of pulmonary valve annulus and observe the infundibular spazm. 術前、術后定期行經胸超聲心動圖檢查,估測最大跨肺動脈瓣壓力階差,並觀察肺動脈瓣形態及其反流情況。
- 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. 右心室和肺動脈內徑隨進藏時間增加呈逐漸增寬趨勢,肺動脈瓣、三尖瓣峰值流速明顯增快。
- 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:經皮肺動脈瓣置換技術對於右心室流出道功能障礙的患者作為非手術治療在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. 這些結構可以防止心室瓣的外翻,就像一把強風中雨傘,當心室收縮的時候心室的壓力就會增加。
- 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. 單純心內修復5例,右室流出道肺動脈瓣下加寬21例,跨肺動脈瓣環加寬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. 結論體外循環下治療小兒重度肺動脈瓣狹窄具較高安全性;
- 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名法洛四聯症病人分成兩個組,A組病人肺動脈功能發育良好,B組病人肺動脈發育不良。
- congenital stenosis of pulmonary valve 先天性肺動脈瓣狹窄
- Congenital absence of pulmonary valve 先天性肺動脈瓣缺失
- Congenital atresia of pulmonary valve 先天性肺動脈瓣閉鎖
- Congenital insufficiency of pulmonary valve 先天性肺動脈瓣閉鎖不全
