Thyroid crisis is a life-threatening form of thyrotoxicosis characterized by multi-system dysfunction. Therapeutic plasma exchange has been reported to be effective in removing excessive circulating thyroid hormones. We present a 46-year-old female with recently diagnosed Graves' disease associated with thyrotoxic cardiomyopathy admitted for thyroid crisis complicated by propranolol-induced circulatory collapse, acute kidney injury and ischemic hepatitis. The tachyarrhythmia was refractory to conventional therapy. Initiation of TPE resulted in rapid clinical and biochemical stabilization.
