When the atrium is not enough, ablation of anteroseptal focal atrial tachycardia from the non-coronary aortic cusp: A case report

BACKGROUND Adenosine-sensitive focal atrial tachycardias (AT) arising from the anteroseptal region are uncommon and may be difficult to ablate safely because of their proximity to the atrioventricular (AV) conduction system. Failure of conventional right or left atrial ablation should prompt consideration of alternative anatomical sites. CASE SUMMARY A 64-year-old caucasian man with no structural heart disease presented with recurrent adenosine-sensitive supraventricular tachycardia. Electrophys
