Guide extension, unmissable tool in the armamentarium of modern interventional cardiology. A comprehensive review

Area of Science:

• Interventional Cardiology
• Medical Devices
• Vascular Interventions

Background:

• Aging populations are increasing the prevalence of complex coronary lesions requiring percutaneous coronary intervention (PCI).
• Despite advancements, challenging lesion anatomies continue to pose difficulties for procedural success in PCI.
• Guide-extensions (GE) are specialized catheters designed to aid device delivery in complex scenarios.

Purpose of the Study:

• To provide a comprehensive review of the applications of GE devices in PCI.
• To specifically focus on the GuideLiner™ (GL), the most commonly used GE device.
• To outline the limitations and provide practical tips for the successful utilization of GE catheters.

Main Methods:

• Literature review of studies and case reports involving GE devices in PCI.
• Analysis of the technical aspects and clinical outcomes associated with GE use.
• Compilation of expert insights on the application and troubleshooting of GE catheters.

Main Results:

• GE devices, particularly the GuideLiner™ (GL), offer versatile solutions for complex PCI scenarios.
• Successful device delivery is enhanced by the coaxial support provided by GE.
• The review identifies various applications, limitations, and practical techniques for optimizing GE usage.

Conclusions:

• Guide-extensions (GE) are valuable tools for interventional cardiologists managing complex coronary lesions.
• Proper understanding and application of GE techniques, including the GuideLiner™ (GL), can improve procedural success rates in PCI.
• This review serves as a guide for clinicians seeking to optimize the use of GE devices.
