Randomized Comparison Between Radial and Femoral Large-Bore Access for Complex Percutaneous Coronary Intervention

ABSTRACT

OBJECTIVES - The aim of this study was to investigate whether transradial (TR) percutaneous coronary intervention (PCI) is superior to transfemoral (TF) PCI in complex coronary lesions with large-bore guiding catheters with respect to clinically relevant access siterelated bleeding or vascular complications.

 

BACKGROUND - The femoral artery is currently the most applied access site for PCI of complex coronary lesions, especially when large-bore guiding catheters are required. With downsizing of TR equipment, TR PCI may be increasingly applied in these patients and might be a safer alternative compared with the TF approach.

 

METHODS - An international prospective multicenter trial was conducted, randomizing 388 patients with planned PCI for complex coronary lesions, including chronic total occlusion, left main, heavy calcification, or complex bifurcation, to either 7-F TR access (TRA) or 7-F TF access (TFA). The primary endpoint was defined as access siterelated clinically significant bleeding or vascular complications requiring intervention at discharge. The secondary endpoint was procedural success.

 

RESULTS - The primary endpoint event rate was 3.6% for TRA and 19.1% for TFA (p < 0.001). The crossover rate from radial to femoral access was 3.6% and from femoral to radial access was 2.6% (p = 0.558). The procedural success rate was 89.2% for TFA and 86.0% for TRA (p = 0.285). There was no difference between TFA and TRA with regard to procedural duration, contrast volume, or radiation dose.

 

CONCLUSIONS - In patients undergoing PCI of complex coronary lesions with large-bore access, radial compared with femoral access is associated with a significant reduction in clinically relevant access-site bleeding or vascular complications, without affecting procedural success.
