"We have a tenant" a right atrial thrombus related to a central catheter.

Hemodialysis tunneled catheter are in constant motion due to the movement of the heart. For that reason catheter tip may cause damage to the wall of the vessel or the atrium, resulting in mural thrombus formation at the point of contact. We report the case of a 36 year old asymptomatic woman with a previous chronic vascular hemodialysis catheter who was referred for routine echocardiogram before kidney transplantation. An ovoid mass compatible with thrombus was present in the right atrium. We review literature about catheter-related thrombus.
