A: Fluoroscopy showing entanglement of the Optrell mapping catheter (Biosense Webster, Irvine, CA) and Impella CP (Abiomed, Danvers, MA). The catheter was carefully disentangled under fluoroscopic guidance. B: Recreation of catheter entanglement outside the body. C: Impella CP (top) along with Optrell mapping catheter (bottom). D: The Impella 5.5 (top) can provide up to 5.5 L of mechanical support through axillary cutdown access and does not use a pigtail, compared to the Impella CP (bottom). The Impella CP pigtail poses a risk for entanglement with the Optrell mapping catheter.
