Why the study?
Does ablation guided by 3D mapping improve symptoms and resolve arrhythmia in a patient with right atrial appendage tachycardia?
Does ablation guided by 3D mapping improve symptoms and resolve arrhythmia in a patient with right atrial appendage tachycardia?
Ablation guided by 3D mapping can successfully treat symptomatic premature atrial contractions and atrial tachycardia originating from the right atrial appendage.
Should not yet change PAC/AT ablation practice; leaves open whether 3D mapping of RAA foci warrants larger evaluation.
A 64-year-old female patient with symptomatic premature atrial contraction (PAC) and atrial tachycardia (AT) referred for EPS (electrophysiologic study) and ablation. EPS and successful ablation were performed guided by a 3D activation mapping system NavX (St. Jude Medical, St. Paul, MN, USA) with complete resolution of symptoms and arrhythmia. Site of origin (SOO) was right atrial appendage (RAA).
