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

This case highlights an atypical association of thrombosis on right and left heart chamber with systemic and pulmonary embolism, related to a hypercoagulable state. Chiari's network is an embryonic remnant with no clinical significance and is exceptionally thrombosed. Failure of treatment by NOAC highlights the complexity of cancer-related thrombosis, particularly in NBTE, and the necessity of heparin and VKA in our case.
