Sumario:Non-bacterial thrombotic endocarditis (NBTE), also known as marantic endocarditis, is a rare form of noninfectious endocarditis presenting with thromboembolism including ischemic cerebral stroke. It is mostly associated with advanced malignancy and characterized by the presence of sterile vegetation on heart valves. The diagnosis is usually based on vegetations seen on an echocardiogram, with negative blood cultures suggesting a noninfectious etiology. The treatment for this condition includes systemic anticoagulation. In this report, we discuss the case of a 61-year-old Caucasian female who presented to our facility with an ischemic stroke. She was found to have vegetations on the mitral valve with negative blood cultures. Further studies revealed metastatic pancreatic cancer. The patient's condition improved following in-hospital management, and she was discharged home for outpatient follow-up and treatment. Through this report, we highlight the importance of considering a search for malignancy in patients presenting with these clinical features. Early diagnosis and prompt management are critical to reduce the complications of NBTE and improve the patients' quality of life.
