Sheathless radial approach in contemporary coronary rotational atherectomy: data from two high-volume centers

Abstract

Aim: To analyze the feasibility and procedural outcome of percutaneous coronary intervention (PCI) using rotational atherectomy (RA), performed via transradial sheathless guiding catheter, as compared to a standard radial and femoral vascular approach.

Methods: All consecutive patients undergoing RA at two high-volume PCI centers from May 2011 to May 2023 were included. Comparisons were made between the two transradial approaches and between the three types of vascular access.

Results: Two hundred twenty-three patients were enrolled. Baseline characteristics were similar, with the exception of gender. We observed, in percentages, fewer cases of failure for sheathless than standard transradial attempts (7.5% vs. 11.5%, respectively), whereas all trans-femoral attempts were successful. Transfemoral procedures were longer and more frequently performed under mechanical circulatory support. There was no difference in procedural success between the three vascular approaches. A trend towards a higher rate of vascular and bleeding complications was found in the femoral group.

Conclusion: Sheathless transradial vascular access is a viable option when performing RA during complex PCI procedures, tending to result in fewer failures than the standard transradial approach and reduced bleeding and vascular complications compared to the femoral method.
