Knife Down
"Knife Down" is what a surgeon says in the OR when she puts her scalpel down so no one gets hurt — and it’s the mission here: put the knife down, long before anyone needs to use it.
Knife Down is a podcast about how to actually invest in your health so you can live longer, stronger, and with less time in doctors’ offices. The core focus is the world’s leading cause of death—cardiovascular disease—and what to do about it before it shows up as a catastrophe.
Hosted by a vascular surgeon on a mission to put herself out of business, the show translates cutting-edge science on prevention, metabolic health, and longevity into real-world strategies you can use in clinic or at your kitchen table. Expect evidence, nuance, and zero wellness hype—plus the occasional dark joke about the state of modern medicine.

My First No Incision Bypass | Advanced Treatment for Arterial Blockages
Use Left/Right to seek, Home/End to jump to start or end. Hold shift to jump forward or backward.
Is it possible to fix a blocked artery without major open surgery? In this video, I explain the Detour procedure (Percutaneous Transmural Arterial Bypass)—a new, minimally invasive technique that routes blood flow around blockages to restore circulation. For patients with advanced peripheral artery disease (PAD), this innovation offers a powerful alternative to traditional leg bypass surgery.
