冠心病(Coronary Artery Disease)超声心动图 冠状动脉粥样硬化性心脏病,简称冠心病,是由于冠状动脉内膜粥样硬化病变,使管腔狭窄、闭塞,使该动脉供应的室壁出现运动减弱、消失,甚至矛盾运动。超声心动图对判断心肌缺血及心肌梗死部位和显示心肌梗死后的并发症,有一定的...
冠状动脉旁路移植术(CABG术),是一种用自体动脉或静脉作为移植物来旁通部分或完全被动脉粥样硬化斑块所阻碍的冠状动脉的一种方法。CABG术是目前最常见的主要外科手术方式之一,在美国每年约进行400000次手术。尽管人口老龄化和越来越多的证据来支持该手术...

冠状动脉扩张(coronary artery ectasis,CAE)是一种少见但容易识别的解剖形态学异常,通常是指心外膜下冠状动脉的局限性或弥漫性扩张,超过邻近正常节段的1.5倍,不同文献定义有所不同。CAE可单发或多发,可为囊状(瘤体横径大于长径)或梭形(瘤体横径小于长...

For over four decades, coronary artery surgery has been shown to relieve angina and extend life expectancy in patients with severe coronary artery disease and to date it remains the gold standard method for coronary revascularization especially in patients with the most severe disease. Pioneered聽in ...
