The concoction of cancer, catheter, and intracardiac clot: a case report describing a potential treatment strategy.

Malignancy and central venous catheters significantly increase the risk of thrombosis. Although low molecular weight heparin is the preferred anticoagulant to manage thrombosis in patients with cancer, direct oral anticoagulants have been proven to be non-inferior. In patients with catheter-related intracardiac thrombus, anticoagulation should be continued for at least 3 months or until the catheter is removed, whichever is longer.
