Polymer Emboli Complicating Transcatheter Aortic Valve Implantation: A Case Report.

Hydrophilic polymers are frequently used as surface coatings in modern intravascular technologies. We hereby present a case of a patient who underwent transcatheter aortic valve implantation that was complicated with foot gangrene and mesenteric ischemia, necessitating emergency enterectomy. Histologic examination revealed hydrophilic polymer emboli as the culprit of these complications. (Level of Difficulty: Intermediate.).
