Introduction to the PATHFINDER Registry and Complex Endovascular Cases With the Auryon Atherectomy System

Peripheral artery disease (PAD) affects an increasingly high number of patients with a spectrum of symptoms. The Auryon laser atherectomy system (AngioDynamics, Inc.) is a solid-state platform with a unique wavelength of 355 nm and short pulse width of 10 to 25 ns that has been demonstrated to provide effective plaque reduction and associated durable clinical results across a wide range of arterial distribution and lesion morphologies, including in-stent restenosis (ISR) and moderate arterial calcification.1,2 However, little is known about the real-world use of the laser system or how safe and effective it is when treating a more complex patient cohort.
