Cardiac sarcoidosis presenting with cardiogenic shock successfully recovered by Impella and corticosteroid pulse therapy: a case report.

We report a case of CS with fulminant haemodynamic collapse treated with high-dose intravenous corticosteroid therapy under Impella assistance for acute haemodynamic support. Although CS has been known as an inflammatory disease with progressive cardiac dysfunction and rapid deterioration due to fatal arrhythmias, it can be improved with steroid therapy. It was suggested that strong haemodynamic support by Impella could be a bridge to manifest the effects after introducing steroid therapy to patients with CS.
