Difficult Management of Coronary Artery Disease in a Patient with Thrombotic Thrombocytopenic Purpura

Abstract

Thrombotic thrombocytopenic purpura (TTP) is a rare syndrome affecting multiple organs. There is no sufficient evidence regarding the clinical cardiac manifestations of TTP. Nonetheless, pathologic cardiac involvement is quite frequent in acute TTP, which is predominantly manifested as myocardial necrosis due to coronary arteriolar microthrombosis. The present case report describes a 43-year-old man with long-standing remitted TTP, who suffered from a sequence of refractory thrombotic epicardial coronary events. Aggressive medical and interventional therapies, including long-term dual antiplatelets and coronary angioplasty, were finally successful in remitting the thrombotic events. During his two-year follow up, he has been asymptomatic.
