SYNPOSIS
The conversation dives into the controversial role of below-the-knee atherectomy in limb salvage, an area where data has long been debated. Dr. Dua, principal investigator of the AMBITION BTK Trial—the first randomized controlled trial comparing below-the-knee atherectomy to angioplasty alone—introduces the trial and explains how it fits into the current body of literature.
Together, the doctors review past evidence, current practice, and the future outlook for tibial interventions. Dr. Dua outlines the wide range of techniques and clinical strategies used to manage PAD, and stresses the importance of physician engagement with the NIH and research community to establish stronger, evidence-based protocols. She also shares her candid thoughts on the most overrated and underrated devices in tibial intervention, highlighting atherectomy’s potential role in vessel preparation before below-the-knee treatment.
