A case of destination therapy for post-fulminant myocarditis with myelodysplastic syndrome.

We encountered a 64-year-old woman who experienced fulminant myocarditis and underwent treatment with veno-arterial extracorporeal membrane oxygenation and Impella CP support. Subsequently, she underwent a device upgrade to Impella 5.5 and received continuous hemodiafiltration for 3 months. During mechanical circulatory support, she developed refractory anemia and thrombocytopenia, leading to a diagnosis of myelodysplastic syndrome. Following the removal of the devices, she no longer required blood transfusions. She received HeartMate 3 left ventricular assist device implantation as a destination therapy indication despite the presence of myelodysplastic syndrome. She was successfully managed by aspirin-free antithrombotic therapy without any hemocompatibility-related adverse events for 4 months after index discharge on foot. We present a patient with a unique and rare presentation, wherein HeartMate 3 was implanted and successfully managed without aspirin to prevent bleeding complications associated with myelodysplastic syndrome.
