目的探讨二尖瓣口血流频谱和瓣环的组织多普勒频谱与左室平均舒张压的关系。
Objective To determine the relationship between left atrial diameter and mitral valve area or left atrial mean pressure in patients with rheumatic pure mitral stenosis.
二尖瓣口血流频谱测值一般反映了左室舒张功能状态,但对几例出现的“伪正常”频谱表现难以明确评价。
Mitral valve flow spectrum commonly reflect the state of left ventricular diastolic function, but several cases with pseudonormalization spectrum can't be clearly assessed.
将m型取样线置于二尖瓣口左室流入道至心尖获取彩色左室舒张期血流传播图测量fpv。
Color m mode Doppler echocardiography studies were obtained from mitral valve orifice toward the apex: the rate of flow propagation velocity (FPV) from apical 4 chamber views.
结果:在观察到二尖瓣口左房侧负向血流的同时,在其左房的相对面可测到前向性血流。
RESULTS: the reverse flow were detected at the mitral valve orifice of left atrium, at the opposite of which in left atrium the front flow were also detected.
结果表明,M型彩色多普勒血流会聚法与二维彩色多普勒血流会聚法在检测二尖瓣狭窄瓣口面积方面基本可靠,但两者的准确性无显著差异。
It was concluded that M-mode and two-dimensional color Doppler flow convergence region could be used to quantificate the area of mitral stenosis accurately.
