A simple yet novel solution to prevent stent stripping in Guidezilla use

Guide extension catheters are particularly useful when performing percutaneous coronary intervention (PCI) in coronary arteries with difficult anatomy, for example, coronary ostial occlusions that cannot be easily accessed or cannulated with routinely used guide catheters, highly calcified and tortuous coronary arteries, and chronic total occlusions (1-5). Guide extension catheters facilitate complex procedures by enabling deep coronary artery cannulation, thereby increasing back-up support and allowing coaxial alignment (2, 5).
