guidewire escalation
Sequential use of increasingly supportive or penetrative guidewires when standard wires fail to cross challenging lesions.
Full Definition
A systematic approach to overcoming difficult coronary anatomy by progressively advancing from conventional guidewires to more specialized designs with enhanced support, torque response, or penetration capabilities. Guidewire escalation typically follows a logical sequence based on lesion characteristics, beginning with standard workhorse wires and advancing through intermediate support wires to highly supportive or dedicated chronic total occlusion wires as needed. The strategy balances efficacy in crossing challenging anatomy with minimization of vessel trauma and perforation risk inherent in more aggressive wire designs.
Usage
Usage note: Single word compound; distinguish from emergency wire exchanges.
