Nonbacterial Thrombotic Endocarditis in a 78-Year-Old Female With Recurrent Acute Ischemic Stroke: A Case Report.

Nonbacterial thrombotic endocarditis (NBTE) is a rare but serious complication, particularly in patients with malignancies like acute myeloid leukemia (AML), where a hypercoagulable state increases the risk of embolic events. This case report describes a rare and complex presentation of marantic endocarditis in a 78-year-old female with relapsed AML. The uniqueness of this case lies in the intersection of a hypercoagulable state induced by AML and the resultant NBTE, leading to recurrent embolic strokes, despite oral anticoagulation.
