Core Tip
Core Tip: Transradial intervention (TRI) has been widely used due to its advantages compared with the transfemoral approach. In TRI, poor back-up support may result in failure of the balloon or stent to reach the targeted lesion. A rapid exchange guide extension catheter provides convenient and efficient back-up support in the TRI procedures. The findings of our study revealed the efficacy and safety of the rapid exchange extension catheter for the balloon and stent delivery in the treatment of type B2/C nonocclusive coronary lesions. The rapid exchange extension catheter technique is a useful approach for complex coronary lesions via the radial access.
