本研究旨在评价3.0T对比剂增强全心冠状动脉MRA（CMRA）显示心脏静脉解剖的价值。在心脏起搏治疗（CRT）中，左心室（LV）起搏是通过将LV电极导线定位在冠状窦（CS）的一个支流中来实现的。静脉解剖结构的植入前知识可能有助于确定CRT的经静脉LV电极导线置入是否可行。回顾性分析了51例在3.0T条件下进行对比增强的全心脏CMRA的图像。使用心电图触发、导航器门控、反转恢复准备、分段梯度回波序列进行数据采集。使用32元件心脏线圈进行数据采集。使用4分量表对心静脉的可见性进行视觉分级（1：差-4：优）。配对Student t检验用于评价前后和上下方向CS口直径的差异。最后对48例有三种解剖变异的受试者的心脏静脉进行了评价。CS口上下径（1.13 ± 0.26）cm大于前后径（0.82 ± 0.19）cm（P < 0.05）。冠状窦、后室间静脉、左心室后静脉、左缘静脉和前室间静脉的平均可见性评分分别为4.0 ± 0.0、3.4 ± 0.5、3.4 ± 0.5、3.0 ± 0.8和3.3 ± 0.5。因此，3.0T的对比增强全心CMRA可以显示正常和变异的心脏静脉解剖结构。
This study was designed to evaluate the value of contrast-enhanced whole-heart coronary MRA (CMRA) at 3.0T in depicting the cardiac venous anatomy. In cardiac resynchronization therapy (CRT), left ventricular (LV) pacing is achieved by positioning the LV lead in one of the tributaries of the coronary sinus (CS). Pre-implantation knowledge of the venous anatomy may help determine whether transvenous LV lead placement for CRT is feasible. Images of 51 subjects undergoing contrast-enhanced whole-heart CMRA at 3.0T were retrospectively analyzed. Data acquisition was performed using electrocardiography-triggered, navigator-gated, inversion-recovery prepared, segmented gradient-echo sequence. A 32-element cardiac coil was used for data acquisition. The visibility of the cardiac veins was graded visually using a 4-point scale (1: poor–4: excellent). The paired Student t test was used to evaluate differences in diameters of the ostium of the CS in anteroposterior and superoinferior direction. The cardiac veins were finally evaluated in 48 subjects with three anatomic variations. The diameter of the CS ostium in the superoinferior direction (1.13 ± 0.26 cm) was larger than in the anteroposterior direction (0.82 ± 0.19 cm) (P < 0.05). The mean visibility score of CS, posterior interventricular vein, posterior vein of the left ventricle, left marginal vein, and anterior interventricular vein was 4.0 ± 0.0, 3.4 ± 0.5, 3.4 ± 0.5, 3.0 ± 0.8, and 3.3 ± 0.5, respectively. In conclusion, contrast-enhanced whole-heart CMRA at 3.0T can depict the normal and variant cardiac venous anatomy.
