【摘要】 目的探讨定量组织速度成像(QTVI)对冠脉搭桥术患者疗效评价的价值。方法运用QTVI检测11例冠心病患者冠脉搭桥术术前、术后前降支对应室壁的收缩期峰值速度、舒张早期峰值速度、舒张晚期峰值速度(Vs、Ve、Va)。结果冠脉搭桥术后患者的前壁基部、前间隔基部、前间隔中部的Vs分别为(3.40±1.21)cm/min,P<0.05、(2.99±1.05)cm/min,P<0.05、(2.01±0.61)cm/min,P<0.005。结论QTVI可定量评价冠脉搭桥术患者术前术后室壁运动速度的变化,是评价冠脉搭桥术的疗效的一种简便有效的方法。更多还原

【Abstract】 Objective To know the value of quantitative tissue velocity imaging(QTVI) in detecting the short effect after coronary artery bypass grafting(CABG).Methods The systolic velocity(Vs),early rapid relaxation velocity(Ve) and atrial contraction velocity(Va) in 11 patients with coronary heart disease before or after CABG were detected by QTVI.Results The Vs in anterior wall base after CABG was(3.40±1.21)cm/min,P<0.05.The Vs in anterior septum base after CABG was(2.99±1.05)cm/min,P<0.05.The Vs in anterior septum midst after CABG was(2.01±0.61)cm/min,P<0.005.Conclusion QTVI is able to assess quantitatively the change of the velocity of left ventricular motion before CABG or after CABG.QTVI provides a new accurate method in follow-up of outcomes of CABG.更多还原
