Embolized Hydrophilic Coating Polymers Found in Left Ventricular Assist Device Apical Core Specimen

Left ventricular assist devices are increasingly used in patients with advanced heart failure. Gross and histologic evaluation of myocardial apical core specimens, extracted during device placement, can provide important insights. Herein, we describe a case of hydrophilic polymer embolization with associated foreign-body giant cell reaction discovered during apical core evaluation. (Level of Difficulty: Advanced.).
