Radiofrequency ablation using a 3D mapping system successfully treated a rare case of right atrial appendage tachycardia complicated by tachycardia-induced cardiomyopathy and cardiogenic shock.
Hypothesis-generating for 3D mapping ablation in rare right atrial appendage tachycardia with cardiomyopathy; prospective studies needed before wider adoption.
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.

Bokhari et al. (2013) conducted a case report in Right atrial appendage tachycardia induced cardiomyopathy (n=1). Radiofrequency ablation using 3D mapping system (NavX) was evaluated on Termination of tachycardia and normalization of LV function. Radiofrequency ablation using a 3D mapping system successfully terminated incessant right atrial appendage tachycardia and normalized left ventricular function in a 40-year-old patient.
