Unusual intraatrial reentry following the Mustard procedure defined by multisite magnetic electroanatomic mapping.
This report describes a patient with d-TGA post Mustard repair who presents with atrial arrhythmias. Two distinct intraatrial reentrant tachycardias were discovered and successful catheter ablation was performed in a unique atrial location not previously described. This case also explores the use of magnetic electroanatomic mapping in guiding catheter ablation.
