Noncontact and electroanatomic mapping of atrial flutter in surgically repaired sinus venosus atrial septal defect and rerouting of anomalous pulmonary venous drainage.
Atypical atrial flutter with two prior failed ablations, complicating surgically repaired sinus venosus atrial septal defect and partial anomalous pulmonary venous connection, mapped by noncontact and electroanatomic mapping, is described. Electroanatomic and noncontact mapping clearly identified a narrow zone of normal voltage and activation which was targeted, with successful termination of the arrhythmia.
