Right atrial mass following transcatheter radiofrequency ablation for recurrent atrial fibrillation: Thrombus, endocarditis or mixoma?

Abstract

We report a case of an asymptomatic patient in whom a right atrial mass was fortuitously documented by echocardiography few months after a transcatheter radiofrequency catheter ablation for recurrent AF. No masses were seen in the cardiac chambers before the ablative procedure, raising important diagnostic and decision-making issues. The patient was referred to the surgeon and a diagnosis of right atrial myxoma was made.
