title: Right atrial appendage tachycardia: A rare cause of tachycardia induced cardiomyopathy with successful radiofrequency ablation using the 3D mapping system.
abstract: We report the case of a 40-year-old patient with incessant supraventricular tachycardia (SVT). As this SVT was resistant to medical therapy and was complicated by severe LV dysfunction and cardiogenic shock, the patient was referred for EPS (electrophysiologic study) and ablation. EPS and successful ablation of the right atrial appendage (RAA) tachycardia were performed by means of a 3D mapping system NavX (St. Jude Medical, St. Paul, MN, USA) with complete resolution of symptoms and normalization of LV function, as evaluated at three-month follow-up examination.
