Mapping and ablation of a perisinusal atrial tachycardia with noncontact mapping.

Perisinusal atrial tachycardia may represent a challenging situation due to unsustained burst characterizing the arrhythmia, sensitivity to bumping, and potential complications including sinus node ablation. This case describes the use of a noncontact mapping system to map and ablates this arrhythmia. Benefit of this technology is described.

A randomized trial of circumferential pulmonary vein ablation versus antiarrhythmic drug therapy in paroxysmal atrial fibrillation: the APAF Study.

Objectives: We compared ablation strategy with antiarrhythmic drug therapy (ADT) in patients with paroxysmal atrial fibrillation (PAF).

Background: Atrial fibrillation (AF) ablation strategy is superior to ADT in patients with an initial history of PAF, but its role in patients with a long history of AF as compared with ADT remains a challenge.

Methods: One hundred ninety-eight patients (age, 56 +/- 10 years) with PAF of 6 +/- 5 years' duration (mean AF episodes 3.

Robotic magnetic navigation for atrial fibrillation ablation.

Objectives: We assessed feasibility of magnetic catheter guidance in patients with atrial fibrillation (AF) undergoing circumferential pulmonary vein ablation (CPVA).

Background: No data are available on feasibility of remote navigation for AF ablation.

Methods: Forty patients underwent CPVA for symptomatic AF using the NIOBE II remote magnetic system (Stereotaxis Inc.
