  • Title: [Atrial tachycardia ablated from the non-coronary aortic cusp].
    Author: Baszko A, Krzyzanowski K, Zinka E, Grajek S.
    Journal: Kardiol Pol; 2007 Feb; 65(2):209-13. PubMed ID: 17366369.
    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.
