Slender Sheath/Guiding Catheter Combination vs. Sheathless Guiding Catheter for Acute Coronary Syndrome: A Propensity-Matched Analysis of the Two Devices

Figure 3

Sheathless transradial percutaneous coronary intervention procedure. (a) A central dilator is introduced into a guiding catheter. (b) A 4-Fr conventional sheath is inserted into the radial artery. (c) Following introduction, the sheath is exchanged for a sheathless guiding catheter connected to a supplied central dilator over a 0.035-inch wire. (d) A silicon-based stopper is linked to the proximal shaft of the sheathless guiding catheter and anchored to a surgical drape using forceps to avoid slippage.
