Three hundred patients were examined to determine the value of the caudocranial right anterior oblique view (RAO) in revealing or improving visualization of lesions in the proximal and mid-left anterior descending artery (LAD), the origins of the septal and diagonal arteries, and the distal branches of the right coronary artery (RCA). The proximal and mid-LAD were shown to greater advantage in 80% of cases, the diagonal arteries in nearly 75%, the septal vessels in more than 90%, and the posterior descending and posterolateral branches of the distal RCA in more than 80%; in addition, the cranial RAO view revealed previously unsuspected lesions in 7% of the proximal and mid-LAD arteries and 26% of the septal vessels. In addition to superior visualization, this view gives satisfactory exposure even in extremely large patients and may also be helpful in coronary angioplasty.
对300例患者进行检查，以确定头足位右前斜位（RAO）在显示或改善左前降支近端和中段（LAD）、间隔支和对角支动脉起源以及右冠状动脉（RCA）远端分支病变的可视化方面的价值。在80%的病例中，LAD近端和中段显示效果更佳，近75%的病例中对角支动脉显示效果更佳，超过90%的病例中间隔血管显示效果更佳，超过80%的病例中RCA远端的后降支和后外侧分支显示效果更佳；此外，头位RAO视图在7%的LAD近端和中段动脉以及26%的间隔血管中发现了之前未被怀疑的病变。除了具有更好的可视化效果外，该视图即使在体型极大的患者中也能提供令人满意的暴露，并且在冠状动脉血管成形术中可能也有帮助。
