Overview
There is no treatment for nonbacterial thrombotic endocarditis; the mainstay of therapy is the identification and treatment of the underlying condition, with an aim to reduce the risk of systemic embolism. Unless there is a specific contraindication, anticoagulation with IV unfractionated heparin or subcutaneous low molecular weight heparin is recommended in all patients with a clinical diagnosis of NBTE.
Medical Therapy
- Pharmacologic medical therapy is recommended among all patients with non-bacterial thrombotic endocarditis[1].
- Due to the fragility of vegetation and the high rate of embolization in patients with NBTE, anticoagulation is recommended provided there are no contraindications[2].
- As there is a risk of conversion of embolism to hemorrhage, a base-line head CT is recommended prior to the start of anticoagulants[3].
- IV unfractionated heparin or subcutaneous low molecular weight heparin is recommended[3].
- Provided there are no acute contraindications, anticoagulation should be continued indefinitely in all patients[4][5].
