查询词典 valvular

Objective:To study the association between mitral valvular filling energy and energy efficiency under different conditions and valvular work efficiency.

目的：研究二尖瓣口充盈能量和能量效率与瓣口工作效率之间的关系。

We chose 15 cases of valvular heart disease mitral stenosis with pulmonary hypertension undergoing mitral valvular replacement.

选择15例风心病合并肺动脉高压行择期瓣膜置换术的患者，在体外循环前、后吸入40 ppm nO气体。

These women, ages 61, 72 and 74 years, receiving long-term pergolide therapy for Parkinson's disease or restless legs syndrome, had valvular abnormalities strikingly similar to those induced by fenfluramine, ergot derivatives, or carcinoid. All three had severe, unexplained tricuspid regurgitation; two had predominantly right-sided congestive heart failure; and two had moderate aortic and mitral valve regurgitation. Histology revealed surface fibroproliferative lesions with preserved underlying valve architecture. Carcinoid was excluded, and none of the patients had taken anorectic drugs or ergots other than pergolide.

这3位妇女年龄分别为61、72及74岁，都长期服用pergolide来治疗帕金森氏症或睡眠脚动症，而且也都有不明原因的严重三尖瓣闭锁不全，就像因fenfluramine、麦角衍生物，或类癌肿瘤所引起的瓣膜异常情形一样；其中2位主要有右心衰竭，2位有中度的主动脉及二尖瓣的闭锁不全，组织学检查显现表面有纤维增生性的损伤，但瓣膜的结构仍然还在；类癌是被排除在外的，而且这3位妇女除了pergolide之外，都不曾服用过厌食剂或麦角类药物。

The most valuable role that CMR plays in patients with valvular heart disease is in determination of left and right ventricular function with a lesser role for precise identification of valve anatomy such as identification of bicuspid aortic valves, vegetations, etc.

CMR在瓣膜性心脏病患者中发挥的最有价值的作用就是测定左，右心室功能，较有价值的作用就是精确鉴定瓣膜的解剖，如二叶主动脉瓣、赘生物等。

Capsule valvular, rarely opening in calyptra fashion.

蒴果瓣裂，很少用帽状体方式打开。

However, we are starting to see an increase in the treatment of valvular heart disease in the catheterization laboratory.

相比之下，可以看到在导管室中治疗瓣膜疾病的患者人数增加。

The percutaneous balloon mitral valvuloplasty was performed in the patient with single thickened tendinous cordae.The valvular closed commissurotomy was performed in the patient with thickened non-calcified tendinous cordae.The ATC stereoscopic images that revealed by dynamic 3-D reconstruction technique could be not acquired in two-dimensional image technique.

结果：本组瓣膜病患者，有两组腱索增粗并钙化者及腱索稀疏与断裂者均行瓣膜置换术，仅单组腱索增粗者行瓣膜球囊扩张术，两组腱索增粗而无钙化者行瓣膜闭式分离术，动态三维重建技术展示了二维显像所不能获得的房室瓣腱索的立体图像。

Now what we finally came up with is that it is still the most robust and the best way to evaluate valvular stenosis by reporting a composite of peak transvalvular velocity, mean gradient and continuity equation valve area.

我们最终得到的结果是，跨瓣峰流速、平均梯度和瓣膜面积的复合指标仍然是最稳定和有效的评价瓣膜狭窄的方法。

Background— Fetuin-A is a multifunctional hepatic secretory protein that inhibits dystrophic vascular and valvular calcification.

背景---胎球蛋白A是具有多功能由肝脏分泌的蛋白质，它抑制了营养不良性血管和心瓣膜钙化的发生，较低的胎球蛋白A血清浓度和肾终末期疾病患者的心瓣膜钙化是相联系的。

The initial association between the development of valvular heart disease and drugs stems from observations made during the use of methysergide and ergotamine for migraine prophylaxis in the 1960s.

心脏瓣膜病的发生与药物之间的联系，最初在20世纪60年代应用美西麦角和麦角胺预防偏头痛发作时观察注意到。

A major factor in deviation from optimal performance of the activated sludge secondary clarifier is the presence of density currents,resulting from the density difference and temperature difference.

异重流的形成是影响活性污泥系统二沉池水力学性能的主要因素，形成异重流的主要原因包括沉淀池内不均匀的污泥分布和温度分布。

You always nip it in the bud.

你总是有办法解决的。
