Abstract

We present a case of a patient with drug resistant atrial tachycardia which was ablated from the noncoronary aortic cusp. Tachycardia was adenosine-sensitive and was characterized by a long RP’ interval and low amplitude P waves (biphasic in II, III, aVF and V1-V2 leads, and positive in aVL). The earliest atrial activation during tachycardia was recorded at His region and from non-coronary aortic sinus of Valsalva. RF ablation at this area terminated tachycardia and did not impair atrio-ventricular conduction.
