In this episode, we'll visit the frontiers of vascular neurology, discussing an important but little-understood category of strokes — embolic strokes of undetermined source, or ESUS. We'll hear from Dr. Hooman Kamel, division chief of neurocritical care at Weill Cornell Medicine. Dr. Kamel is a co-principal investigator for the ARCADIA trial, which is testing anti-thrombotic strategies in patients with cryptogenic stroke and atrial cardiopathy. He was interviewed by ANA Member Michelle Johansen, a vascular neurologist and assistant professor of neurology at Johns Hopkins. Series 1, Episode 11
