Treatment of coronary chronic total occlusion by transradial approach: Current trends and expert recommendations
Abstract
The aim of this review is to highlight the technical details and the scientific data on percutaneous coronary interventions (PCIs) in chronic total occlusion (CTO) performed by transradial approach (TRA). Transfemoral approach (TFA) is commonly regarded as the standard for CTO PCI, but there is a growing number of CTO recanalization procedures performed by TRA. We discuss the relevant technical details to approach a CTO by transradial access, especially the compatibility of various CTO recanalization techniques with specific guiding catheter sizes. Randomized prospective trials in this field are lacking and only data from observational studies are available. We can conclude that transradial access for CTO PCI is feasible and could be very useful in selected patients. In our opinion, transradial access in CTO PCIs should be limited to operators and centers highly experienced in CTO recanaliza¬tion and in TRA.
