Electroanatomic Mapping-Guided Radiofrequency Ablation of Adenosine Sensitive Incessant Focal Atrial Tachycardia Originating from the Non-Coronary Aortic Cusp in a Child

چکیده
Incessant focal atrial tachycardia may be encountered in the pediatric age group although it is rarely seen. Ablation using radiofrequency or cryothermal energy is the preferred method for drug-resistant cases. Recently, 3D electroanatomic mapping systems have been increasingly used for mapping and ablation. In this report, we presented, for the first time, a pediatric case with incessant focal atrial tachycardia originating from the non-coronary aortic sinus and ablated using 3D electroanatomic mapping system.

Adenosine sensitive focal atrial tachycardia originating from the non-coronary aortic cusp.
We report on the characteristics and the ablation procedure of a focal atrial tachycardia originating from the non-coronary aortic cusp. The electrophysiological features of the tachycardia included: (i) incessant pattern; (ii) easy induction and termination by atrial stimulation; (iii) earliest right atrial activation at the para-hisian area; and (iv) termination by adenosine. Left-sided mappi...

We report on an atrial tachycardia (AT), emanating from the non-coronary (NC) aortic cusp, ablated with the aid of an electro-anatomical navigation system. In this setting, the electrocardiographic, electrophysiologic (EP), anatomical, and ablative considerations are discussed.Although NC aortic cusp focal ATs are an uncommon EP finding, their ablation is effective and safe, especially from an ...
متن کاملSuccessful Catheter Ablation of Atrial Tachycardia Originating from the Non-coronary Aortic Sinus
We report a rare case of atrial tachycardia originating from the non-coronary aortic sinus. After failed radiofrequency (RF) energy applications at right His-bundle region, the complete elimination of atrial tachycardia was achieved with an RF energy application in the non-coronary aortic sinus. With the review of other papers, this report emphasizes the importance of mapping in the non-coronar...

Patient Characteristics and Electrophysiological Study A 56-year-old diabetic woman who had a history of frequent palpitations associated with syncope resistant to both amiodarone and propafenone was referred for catheter ablation after a failed ablation for a focal AT in the right atrium (RA). At the initial procedure, the earliest atrial activation was located at the ostium of the superior ve...

OBJECTIVES We sought to investigate electrophysiological characteristics and catheter ablation in patients with focal atrial tachycardia (AT) originating from the non-coronary aortic sinus (AS). BACKGROUND In patients with failed ablation of focal AT near the His bundle (HB) region, an origin from the non-coronary AS should be considered because of the close anatomical relationship.
