冠状动脉狭窄严重度的估计关系到临床治疗方式的决择和预后判断的依据.传统的冠脉造影按直径狭窄百分比分级脱离了解剖与生理联系,低估了弥漫性冠脉血管病变的程度.近年来多种新的交叉性检测技术从静态与动态、平面与立体分析模式加强了冠脉狭窄解剖与功能联系,形成了多方位定量评价冠脉狭窄血动学的新格局.数字化技术和数学模型的建立则增加了各探测手段的效能、精度与速度.
Estimation of the severity of coronary artery stenosis is related to the choice of clinical treatment and the basis for the prognostic judgment.Traditional coronary angiography graded by the percentage of diameter stenosis broke away from the anatomy and physiology and underestimated the extent of diffuse coronary lesions. To a variety of new cross-detection technology from static and dynamic, planar and three-dimensional analysis of the pattern of enhanced coronary stenosis anatomy and function of the formation of a multi-directional quantitative evaluation of coronary artery stenosis new pattern of digital technology and mathematical models The establishment of an increase of the efficiency of the means of detection, accuracy and speed.
