Description

Mikio Shiba and colleagues report a sixty-six-year-old man whose care for acute myocarditis was complicated by a clot in the aorta, where two artificial blood flows meet. He came in with chills, breathlessness on exertion, and palpitations. Cardiac enzymes and imaging led to a diagnosis of acute myocarditis. His circulation was unstable. Care used a balloon pump first. Refractory ventricular fibrillation then led to extracorporeal membrane oxygenation with a microaxial flow pump.

Imaging showed an aortic thrombus, formed it seemed in the mixing zone where the two devices' flows collide. Antibody tests then gave a diagnosis of heparin-induced thrombocytopenia, an immune reaction to the anticoagulant itself. So heparin was swapped for argatroban. Surgery restored flow in the artery. The man stabilised and was discharged on day forty-seven.
