Treatment of device thrombus in the HeartWare HVAD: Success and outcomes depend significantly on the initial treatment strategy

In this large multicenter analysis, we observed that medical therapy, as the initial treatment strategy for HeartWare HVAD thrombosis, is associated with low success (48%) and a significant risk of hemorrhagic stroke (21%) and death (10%). However, initial treatment with device exchange was uniformly successful and not associated with significant early morbidity or death. Although the optimal treatment approach for HeartWare HVAD pump thrombosis remains undecided, these data do not support the routine use of medical therapy as an initial treatment strategy.
