【摘要】 目的:评价双源螺旋CT对慢性心力衰竭患者显影冠状静脉系统的应用价值。方法:35例患者,年龄(65.4±8.8)岁,60%男性,分为2组:A组先后行双源螺旋CT扫描及冠状静脉逆行造影(retrograde coronary venography,RCV),B组先后行冠状动脉顺向型心脏静脉造影(coronaryvenography,CVG)及RCV。结果:所有患者冠状静脉窦、心大静脉(GCV)及心中静脉(MCV)的显示率为100%;左室后静脉(LVPV)在A组65%患者显影,而B组66.7%患者显影;MDCT与RCV相关系数为0.944,CVG与RCV的相关系数为0.42。结论:双源螺旋CT可以无创评价冠状静脉系统,提示可能在心脏再同步化治疗(CRT)中具有一定价值。更多还原

【Abstract】 Objective: To evaluate the value of double source multidetector computed tomography(MDCT) in visualization of cardiac veins in patients with chronic heart failure. Methods: Thirty-five patients with chronic heart failure(aged 65.4±8.8,21 males and 14 females) were enrolled in the study.In Group A,MDCT and retrograde coronary venography(RCV)were performed consecutively;in Group B anterograde visualization of the coronary venous and RCV were performed. Results: Coronary sinus,GCV and MCV of all individuals were identified in MDCT.LVPV was observed in 65% patients of Group A,and 66.7% patients of Group B.The correlation coefficient between MDCT and RCV was 0.944,and that between CVG and RCV was 0.42. Conclusions: Non-invasive evaluation of cardiac veins with double source CT is feasible and may be used in cardiac resynchronization therapy.更多还原
