Right Atrial Thrombosis Provoked by Central Venous Catheter: A Case Report

Intracardiac thrombi are not uncommon, but right atrial (RA) thrombi are exceedingly rare. Thrombi can lead to a variety of complications, such as systemic and pulmonary embolism. While various imaging modalities are helpful in the diagnosis, an echocardiogram is the most commonly used one. Principle management of the condition involves anticoagulation. However, management can vary among different patient groups, depending on the location and size of thrombi. We present a case of an RA thrombosis due to dilation of the atria and trauma from an infected central venous catheter in a patient with a past medical history of pulmonary artery hypertension (PAH).
