First Experience Using the Sheathless Hyperion Guiding Catheter System Designed for Direct Insertion

Area of Science:

• Cardiology
• Interventional Cardiology
• Vascular Access

Background:

• Transradial percutaneous coronary intervention (PCI) aims to minimize radial artery trauma.
• Sheathless guiding catheters offer potential advantages over traditional systems.
• The sheathless Hyperion guide catheter (SHGC) system is a novel device for transradial access.

Purpose of the Study:

• To evaluate the first clinical experience with the sheathless Hyperion guide catheter (SHGC) system.
• To assess the safety and efficacy of the SHGC for transradial PCI.
• To determine the feasibility of performing complex PCI using the SHGC.

Main Methods:

• A prospective evaluation of consecutive patients undergoing PCI with radial access and the SHGC.
• Data collected from June 2020 to June 2021, with no exclusion criteria.
• Successful insertion of the SHGC in all attempted radial arteries (128/128).

Main Results:

• The study included 120 patients; SHGC insertion was successful in all cases.
• Coronary artery engagement was achieved in 98.4% of cases, treating 150 complex lesions.
• High rates of angiographic success (99.2%) with low rates of periprocedural myocardial infarction (4.2%) and no major complications.

Conclusions:

• The SHGC system allows for safe and effective direct insertion in transradial procedures.
• The SHGC facilitates complex PCI transradially with a high success rate.
• This represents a promising advancement in transradial interventional cardiology.
