Implication
Remote magnetic navigation appears feasible for SVT ablation in atrial isomerism; leaves open impact on arrhythmia-free survival pending larger studies.
Structured PICO
Does radiofrequency ablation using remote magnetic navigation improve arrhythmia-free survival in adults with atrial isomerism and supraventricular arrhythmias?
P
Population
8 consecutive adults with atrial isomerism (heterotaxy syndrome) and symptomatic supraventricular arrhythmias, who had previously undergone surgical repair or palliation of associated anomalies. Median age 33 years, 5 females.
I
Intervention
Electrophysiological study and radiofrequency ablation using remote magnetic navigation in conjunction with CARTO RMT and three-dimensional (3D) image integration
O
Outcome
Freedom from arrhythmia at follow-uphard clinical
Remote magnetic navigation with 3D mapping is feasible and effective for ablating complex supraventricular arrhythmias in adults with heterotaxy syndrome, requiring very short fluoroscopy times.
