Abstract
Right atrial thrombus is a rare complication of hemodialysis catheter with an incidence of <6 %. New-onset atrial fibrillation can be the first symptom of catheter-related right atrial thrombus (CRAT) in a patient with long-term dialysis catheter. Therefore, evaluation for CRAT is justified in such scenario. We highlight a case report where a new-onset atrial fibrillation led to the discovery of a right atrial thrombus in a patient with long-term dialysis catheter.
