Successful percutaneous coronary intervention (PCI) starts with a coronary guidewire that possesses specific characteristics designed to support advancement through various coronary vasculature anatomies. These wires can be grouped into four major categories based on their construction: stainless steel, hybrid, plastic, and niche. Steel guidewires can be further subdivided based on performance attributes: workhorse wires, which are designed to provide support, torque, and lubricity for passage through various complex anatomies, as well as to allow delivery of stents, catheters, balloons, and other devices; and chronic total occlusion (CTO) wires, which are designed for tackling the complex lesion morphology often associated with CTOs.

Today’s discussion will address the workhorse wire group. Workhorse wires account for about 70% of all coronary wires used; however, there have been precious few technological advances in workhorse wires over the past decade—arguabl...
