Transaortic ablation at the aortomitral junction can successfully eliminate atrial tachycardia originating from this location when right-sided ablation fails.

May support transaortic ablation for refractory aortomitral AT after right-sided failure; hypothesis-generating and requires prospective confirmation.
Atrial tachycardia (AT) originating from the aortomitral junction is a very rare and challenging disease. Its arrhythmic characteristics have not been described in detail compared with the descriptions of the arrhythmic characteristics of AT originating from the other locations. Only a few case reports have documented successful ablation of this type of AT using transaortic or transseptal approaches. We describe a case with AT that was resistant to right-sided ablation near the His bundle failed and transaortic ablation at the aortomitral junction successfully eliminated.

Lee et al. (2014) conducted a case report in Atrial tachycardia (n=1). Transaortic radiofrequency catheter ablation was evaluated on Termination of tachycardia and freedom from recurrence. Transaortic radiofrequency catheter ablation at the aortomitral junction successfully eliminated atrial tachycardia that was resistant to right-sided ablation, with no recurrence at 12 months.
