In this episode of the BackTable Podcast, host Dr. Chris Beck discusses atherectomy, laser technologies, and their use in vessel treatment with Dr. Tony Das, an interventional cardiologist practicing in Dallas, TX and one of the founding members of the VIVA Vascular Education Course in Las Vegas.

Dr. Das shares insights on the PATHFINDER registry, which is a prospective non-randomized, multicenter study to evaluate the performance and outcome of the Auryon laser atherectomy system. Their conversation explores the role of atherectomy in reducing stent usage, decreasing embolization likelihood, enhancing thrombus removal, and uncovering lesions. Dr. Das further provides recommendations for building a successful atherectomy program, utilizing laser technologies, and the importance of having ablative technology in outpatient labs. The doctors forecast future applications for artificial intelligence and remote monitoring.
