Percutaneous transluminal coronary angioplasty (PTCA) of lesions in a right coronary artery with a "shepherd's crook" configuration may pose procedural difficulties due to inadequate guiding catheter back-up support. We evaluated the utility of a new shape of guiding catheter, previously evaluated for PTCA of lesions in the left coronary artery, in five cases with this particular right coronary artery anatomy. Factors responsible for success in these cases relate to the catheter's shape and construction.
对于具有“牧羊人之钩”形态的右冠状动脉病变进行经皮腔内冠状动脉成形术（PTCA）时，由于引导导管的支撑不足可能会带来操作困难。我们评估了一种新型引导导管的效用，该导管此前已在左冠状动脉病变的PTCA中进行过评估，此次用于5例具有这种特殊右冠状动脉解剖结构的病例。这些病例成功的相关因素与导管的形状和构造有关。
