Thrombosis of Chiari's network in the setting of non-bacterial thrombotic endocarditis occurring under non-vitamin K antagonist oral anticoagulation: a case report.

ABSTRACT:

Background

Non-bacterial thrombotic endocarditis (NBTE) is a rare condition characterized by sterile thrombi on undamaged valves. We herein report a case of NBTE involving the Chiari's network and the mitral valve, related to a metastatic cancer, and occurring under non-vitamin K antagonist oral anticoagulant (NOAC).

Case summary

A 74-year-old patient with metastatic pulmonary cancer was diagnosed with a right atrium mass during pre-treatment cardiovascular check-up. Transoesophageal echocardiography and cardiac magnetic resonance concluded that the mass was a Chiari's network. Two months later, the patient was admitted for a pulmonary embolism and started rivaroxaban. At 1-month follow-up, the patient underwent a new echocardiography, which showed an increased size of the r
