Q: Question: Do prior hematologic conditions carry a high morbidity and mortality in patients supported with continuous-flow left ventricular assist devices?
Answer: Patients with a history of prior hematologic conditions are at high risk for bleeding, thrombotic and neurologic events during device support, leading to early mortality. This case series questions the benefit of CF-LVAD in these patients and the appropriate management with regard to anti-coagulation. Further studies on the outcomes of these patients are warranted.
A:
yes
