Principles and Techniques of the Three-Dimensional Electroanatomic Cardiac Mapping Approach in the Treatment of Intractable Atrial Macroreentrant Tachycardia Ablations
Abstract
Introduction:
Challenging
and intractable macroreentrant atrial tachycardias mostly occur after cardiac
surgeries, and the response of such arrhythmias to conventional treatments is
poor. Also, arrhytmias with previous unsuccessful ablations are compulsive
arrhytmias. This study represents our approach for the ablation of challenging
atrial macroreentrant tachycardias.
Patients
and Methods: Five consecutive patients with atrial þutter and a previous
history of cardiac surgery and/or radiofrequency ablation were enrolled to this
study. The focal point of the clinical arrhythmia was deÞned in the CARTO®
and Columbus™ map and the critical isthmus was targeted for ablation.
Radiofrequency ablation was performed until the arrhythmia stopped or until a
change in cycle length or activation wave front was seen.
Results: All the
complex atrial macroreentrant tachycardias were arized from the right atrium.
Overall, all the cases were successfully mapped and ablated. None of the
patients had recurrence even after 6 months of follow-up. The mean (±SD)
procedure time was 49.0 ± 22.4 min. Three-dimensional electroanatomic cardiac
mapping technologies, including CARTO and Columbus™, are highly effective in
revealing atrial arrhytmias and facilitating ablation of the scar-related
potential circuits.
