Corticosteroid therapy promptly improved punctate purpura and acute kidney injury in patients who developed hydrophilic polymer embolism after transcatheter aortic valve replacement.

Hydrophilic polymer embolism is a rare but potentially severe complication of TAVR that may be effectively managed with early diagnosis and corticosteroid therapy.
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.
Kobayashi et al. (Mon,) conducted a case report in Hydrophilic polymer embolism after transcatheter aortic valve replacement (n=3). Methylprednisolone was evaluated. Corticosteroid therapy promptly improved punctate purpura and acute kidney injury in patients who developed hydrophilic polymer embolism after transcatheter aortic valve replacement.
