Real-time 3-dimensional echocardiography (RT3DE) to visualize the coronary sinus (CS) was compared with multislice cardiac tomography (MSCT).
In all, 37 consecutive patients undergoing MSCT received RT3DE a few hours later. Group A (n = 22) had normal left ventricular dimension/function, whereas group B (n = 15) had heart failure.
The CS could be visualized in both groups (91% and 93%) with a significantly larger diameter in B. Systolic CS diameter was always larger than diastolic, but patients with heart failure showed significantly less difference (7.6% +/- 4.2% vs 12.2% +/- 6.1%, P < .05). When systolic and diastolic measurements were possible, MSCT and RT3DE agreed (Lin R = -0.09 [95% confidence interval 0.73-0.93]) but less so from the proximal to mid/distal segments (Lin R 0.90, 0.61, 0.41, respectively). Observers learned the procedure in approximately 5 minutes.
The CS can be visualized and quantitatively assessed by RT3DE in an easily learned procedure that agrees with MSCT results, especially in patients with heart failure.
将实时三维超声心动图（RT3DE）用于观察冠状静脉窦（CS）并与多层螺旋CT（MSCT）进行比较。
共有37例连续接受MSCT检查的患者在数小时后接受了RT3DE检查。A组（n = 22）左心室大小/功能正常，而B组（n = 15）有心力衰竭。
两组中CS均能被观察到（分别为91%和93%），B组中CS直径明显更大。CS收缩期直径总是大于舒张期，但心力衰竭患者两者差异明显更小（7.6%±4.2%对12.2%±6.1%，P <.05）。当可以进行收缩期和舒张期测量时，MSCT和RT3DE结果一致（Lin相关系数R = -0.09 [95%置信区间0.73 - 0.93]），但从近端到中/远端节段一致性逐渐降低（Lin相关系数分别为0.90、0.61、0.41）。观察者大约5分钟就能学会该操作。
RT3DE能够通过一种易于掌握的操作来观察和定量评估CS，且结果与MSCT一致，尤其对于心力衰竭患者。
