Background Radial access is associated with improved outcomes following percutaneous
coronary intervention (PCI); however, its role in complex, high‐risk percutaneous coronary
intervention (CHiP) remains poorly studied. Methods We studied retrospectively all
registered patients's records from the British Cardiovascular Intervention Society dataset and
compared the baseline characteristics, trends and outcomes of CHiP procedures performed
electively between January 2006 and December 2017 according to the access site. Results …

Background Limited data are available on complex high-risk percutaneous coronary
intervention (CHiP) trends and outcomes in nonsurgical centres (NSCs), particularly in
health care systems where most centres are NSCs. Methods Using data from a national
registry, we studied the characteristics and outcomes of CHiP procedures performed for
stable angina from 2006 to 2017 according to the presence or absence of on-site surgical
cover. Multivariate regression analyses and propensity score matching were used to …
