Guidezilla™ guide extension catheter I for transradial coronary intervention.

Area of Science:

• Cardiology
• Interventional Cardiology
• Vascular Medicine

Background:

• Percutaneous coronary intervention (PCI) is a primary treatment for coronary artery diseases (CAD).
• Transradial coronary intervention (TRI) is increasingly preferred for its benefits.
• Evaluating novel devices like the Guidezilla™ guide extension catheter I (GGEC I) is crucial for optimizing TRI procedures.

Purpose of the Study:

• To assess the effectiveness and safety of the GGEC I in TRI.
• To identify indications for GGEC I use in complex coronary interventions.
• To determine if SYNTAX score stratification impacts GGEC I performance in TRI.

Main Methods:

• A case series of 221 patients with CAD undergoing TRI using GGEC I.
• Data collected on patient demographics, lesion characteristics, procedural details, and outcomes.
• Analysis of indications for GGEC I use, including heavy calcification and extreme tortuosity.

Main Results:

• The study included 221 patients with a high prevalence of complex lesions (triple-vessel, chronic total occlusion, type C).
• GGEC I was primarily used for heavy calcification (67%) and extreme tortuosity (12.2%).
• The overall success rate was 94.1% with a mean operation time of 58 minutes. No significant difference in outcomes was observed across SYNTAX score strata. Two cases of subacute thrombosis were reported perioperatively, during hospitalization, and at 1-month follow-up.

Conclusions:

• The GGEC I demonstrates potential advantages for transradial coronary intervention.
• Its effectiveness is not significantly influenced by the complexity of coronary artery disease as indicated by SYNTAX score.
• Careful patient selection and procedural technique are essential for optimal outcomes.
