Abstract 15008: Novel Sheathless Guiding Catheter Equipped With Peel-Off External Dilator for Percutaneous Coronary Intervention With Distal Radial Approach - A Multicenter Study

Abstract

Objectives: Hyperion Sheathless guiding catheter (Asahi Intecc) is a novel guiding system for percutaneous coronary intervention (PCI) which is equipped with peel-off type outer dilator to facilitate smooth insertion of catheter tip. The aim of this study was to access feasibility and efficacy of this system for the patients who underwent PCI through distal radial artery. Methods: A total of 179 patients underwent PCI using a 6-Fr Hyperion sheathless guiding catheter in 2 hospitals. Of those, 168 patients including 27 patients with ST elevation myocardial infarction were treated with distal radial approach. Procedural success, bleeding complication and radial occlusion examined using Doppler ultrasound at discharge was accessed. Results: Mean age of the patients was 72.1 +/- 11.3 years and 114 patients were male. Procedural success was 100 % with no patient requiring conversion to conventional radial access. Doppler ultrasound examination of the distal radial artery at 1-day follow-up was available in all patients, with 2 patients (1.2%) was found to have radial artery occlusion. One patient presented forearm hematoma equivalent to EASY hematoma classification I and 4 patients showed dorsum hematoma. Conclusions: The current study illustrated that the use of the Hyperion Sheathless guiding catheter for distal radial PCI was feasible and associated with a low rate of procedure-related complications even in the patients with ST-elevation myocardial infarction.
