Introduction Although recently published evidence favours transradial access (TRA) when using large-bore guiding catheters for percutaneous coronary intervention (PCI) of complex coronary lesions, the femoral artery will still be used in a considerate proportion of patients undergoing complex PCI, especially in PCI of chronic total occlusions (CTO). Ultrasound-guided puncture of the femoral artery may reduce clinically relevant access site complications, but robust evidence is lacking up to date.

Methods and analysis A total of 542 patients undergoing complex PCI, defined as PCI of CTO, complex bifurcation, heavy calcified lesion or left main, in which the 7-F or 8-F transfemoral access is required, will be randomised to ultrasound-guided puncture or fluoroscopy-guided puncture. The primary outcome is the incidence of the composite end-point of clinically relevant access site related bleeding and/or vascular complications requiring intervention. Access site complications and major adverse cardiovascular events up to 1 month will also be compared between both groups.

Ethics and dissemination Ethical approval for the study was granted by the local Ethics Committee (‘Medisch Ethische Toetsing Commissie Isala Zwolle’) for all Dutch sites, ‘Comité Medische Ethiek Ziekenhuis Oost-Limburg’ for Hospital Oost-Limburg, ‘Comité d’éthique CHU-Charleroi—ISPPC’ for Centre Hospilatier Universitaire de Charleroi and ‘Ethik Kommission de Ärztekammer Nordrhein’ for Elisabeth-Krankenhaus). The trial outcomes will be published in peer-reviewed journals of the concerned literature. The ultrasound guided transfemoral access in complex large bore PCI trial has been administered in the database, reference number: NCT03846752.

Registration details identifier: NCT03846752.
