Abstract: Recently, endovascular catheter-based interventions have become an established therapeutic option for severe valvular heart disease. Although cholesterol crystal embolism is a well-recognized complication of endovascular treatment, the hydrophilic polymer coating of catheter devices may also induce embolic events. Herein, we reported a rare case of hydrophilic polymer embolism (HPE) after transcatheter aortic valve replacement for severe aortic stenosis. At present, there are no specific treatment options for HPE, but early diagnosis and corticosteroid therapy may be effective. This report highlighted the characteristics and successful management of HPE based on a patient we treated and previous literature.
