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

ABSTRACT: Background:Patients with cancer often pose a unique challenge to anticoagulation, as they have a higher risk of bleeding and clotting than the general population. Patients with cancer and catheter-related intracardiac thrombus are a very specific subset of people who do not have specific recommendations guiding their treatment. This article aims to address the existing knowledge gaps in this scenario and provide a possible treatment approach for these patients. Case summary:We describe the case of a 46-year-old lady with invasive breast cancer, who was on chemotherapy through a central venous catheter and was found to have a right atrial thrombus on routine echocardiography. Due to the paucity of data in this scenario and because the patient requested an oral anticoagulant which did not need frequent monitoring, we started her on apixaban for a total of 3 months. Echocardiogram was repeated at 4 and 8 weeks. In the 8-week echocardiogram, the right atrial thrombus was no longer visualized. Discussion: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.
