查询词典 mitral

The heart has been sectioned to reveal the mitral valve as seen from above in the left atrium.

此心脏已经被切割成两半，在左心的上方可见二尖瓣。

On examination, he has a resting tachycardia and eidence of left entricular dilatation with a displaced apex beat and possible secondary mitral regurgitation.

体检发现有静息时心动过速与左心室扩大依据，心尖搏动偏移，可能有二尖瓣返流。

On examination, he has a resting tachycardia and evidence of left ventricular dilatation with a di laced apex beat and po ible secondary mitral regurgitation.

体检发现有静息时心动过速与左心室扩大依据，心尖搏动偏移，可能有二尖瓣返流。

Objective To examine whether transesophageal echocardiography is better than transthoracic echocardiography in the detection of partially ruptured mitral chordae tendineae.

目的 比较经胸超声心动图及经食管超声心动图对二尖瓣腱索部分断裂的诊断价值，探讨TEE对该病的探测方法及其声像学特征。

Just like the mitral valve, the leaflets have thin chordae tendineae that attach the leaflet margins to the papillary muscles of the ventricular wall below.

与二尖瓣一样，瓣叶有薄博的键索连接着瓣叶边缘与心室壁上的乳头肌。

Here are flat, pale tan, spreading vegetations over the mitral valve surface and even on the chordae tendineae.

小疣状赘生物呈串珠状沿着心脏瓣膜的闭锁缘排列。

Methods Thirty patients with chronic mitral regurgitation were c lassified into three groups. Twelve patients underwent conventional MVR, 10 patients had MVR with preservation of posterior chordae tendin eae only, and 8 patients had MVR with preservation of both anterior and posterior chordae tendineae.

根据MVR的不同方式，将30例慢性二尖瓣反流患者分为3组：A组为传统的MVR即完全切除瓣叶及其腱索患者12例，B组为完全切除前叶及其腱索仅保留后叶及其腱索的MVR患者10例，C组为切除部分前叶但保留前叶腱索和后叶及其腱索的MVR患者8例。

However, mechanical prosthetic valve has poor biocompatibility, and biological valve is easy to degrade and to be damaged. People have studied a new material to make valve. Giant molecule materials-made no-stent bio-mitral valve with chordae tendineae is similar to normal valve.

生物瓣具有血流动力学性能优秀，不需终生抗凝等优点，但机械瓣的生物相容性较差、生物瓣易退化损坏等问题，使人们开始对新的瓣膜制作材料进行研究，使用高分子材料制成的无支架带腱索生物二尖瓣与自然瓣膜相似，可维持人体二尖瓣生理功能、左室几何形状和血流动力学。

In all,10 patients were cured after mean follow-up 15.3±12.8 months.The causes of RFCA failure were demonstrated in surgical operation.In 3 patients without structural heart disease,ablation catheters were not located in distinct target sites during ablation of 2 left posteroseptal pathways and 1 right posterior wall pathway.In 2 cases of Ebstein?s anomaly,ablations were failed by serious tricuspid regurgitation and AP at epicardium.In one case with rhumatic valvular disease,ablation catheter did not achieve mitral annulus because of pathologic changes.Other 4 cases with congenital heart disease were associated with anotomical anomaly and serious hemodynamic disturbance.

s畸形合并房间隔缺损，1例为重度三尖瓣返流使消融电极不能稳定贴靠靶点，另1例为AP靠近心外膜面而致RFCA失败；1例风湿性心脏病联合瓣膜病因瓣膜及瓣下结构病理改变致RFCA失败；1例重度二尖瓣返流RFCA失败与病人不能耐受RFCA与AP定位于24区消融导管难以抵达有关；先天性心脏病大房间隔缺损、重度主动脉关闭不全及矫正性大动脉转位右旋心伴三尖瓣返流各1例，RFCA失败与解剖畸形、心内大分流等血液动力学障碍有关。

Results In univariate analysis, atrial fibrillation, huge left atrium, long course of left-sided valve diease, degradation of left heart function （LVEF 〈0.50）, tricuspid rheumatic pathological change, enlarged right atrium and single mitral valvar disease were significant risk factors of TR devdopment.

结果单因素分析显示心房纤颤、巨大左房、左心瓣膜病病程长、左心功能低下（LVEF〈0.50）、右房增大（≥50mm）、三尖瓣风湿性病变及单纯二尖瓣病变是继发性TR进行性加重的危险因素；多因素分析显示心房纤颤、巨大左房、左心瓣膜病病程长及三尖瓣风湿性病变是继发性TR进行性加重的危险因素；远期随访显示，B组心功能改善明显优于A组，TR程度明显低于A组，C组术后无1例发生TR。

And Pharaoh spoke to Joseph, saying, Your father and your brothers have come to you.

47：5 法老对约瑟说，你父亲和你弟兄们到你这里来了。

Additionally, the approximate flattening of surface strip using lines linking midpoints on perpendicular lines between geodesic curves and the unconditional extreme value method are discussed.

提出了用测地线方程、曲面上两点间短程线来计算膜结构曲面测地线的方法，同时，采用测地线间垂线的中点连线和用无约束极值法进行空间条状曲面近似展开的分析。
