Virtual 5-French intra-aortic pumping using a Glidesheath Slender and 6-French intra-aortic balloon catheter.

Objectives: The aim of this study was to evaluate the feasibility and safety of the 6-Fr Glidesheath Slender, which has equivalent outer size to the conventional 5-Fr sheath, for use with the 6-Fr intra-aortic balloon pump (IABP) catheter.

Methods: Between May 2014 and March 2015, 24 patients with acute coronary syndrome underwent percutaneous coronary intervention using a 6-Fr IABP catheter through a 6-Fr Glidesheath Slender for support. The adverse events, including access site complications, kinking of the sheath during the procedure, and any evidence of balloon pump failure, were retrospectively investigated.

Results: Insertion of the IABP catheter through either the femoral or brachial artery was successful in all patients. The mean support time was 32.4±22.0h. No major hemorrhagic event or severe limb ischemia was observed. Kinking of the shaft occurred during insertion in one patient; however, the subsequent balloon pumping was well maintained and did not require exchange of the sheath or IABP catheter. No kind of IABP failure was observed.

Conclusion: Although this sheath was originally designed to allow radial access, our results suggest that the use of the Glidesheath Slender is feasible for insertion of the 6-Fr IABP catheter through the brachial and femoral arteries, and may reduce vascular complications in patients who undergo percutaneous coronary intervention.
