Catheter ablation of the anteroseptal accessory pathway from the noncoronary aortic cusp in a pediatric patient
نویسندگان
چکیده
For patients with Wolff-Parkinson-White (WPW) syndrome, several algorithms have been published for the prediction of the location of accessory pathways (APs) from the QRS morphology on the ECG. Hence, these algorithms may fail to identify the locations of midseptal or right APs (1, 2). APs may traverse the central fibrous trigone or involve the right atrial appendage; these may be mistaken as anteroseptal APs and be an uncommon source of ablation failure (3). Here we report a case of WPW syndrome with anteroseptal APs in which ablation was successfully performed from the non-coronary aortic cusp (NCAC).

Catheter ablation of anteroseptal accessory pathways from the aortic cusps: A case series and a review of the literature
Data regarding catheter ablation of anteroseptal accessory pathways through the aortic cusps are limited. We describe two cases of true para-Hisian accessory pathways successfully ablated from the aortic cusps (right coronary cusp and non-coronary cusp, respectively) along with a review of the current literature. Due to the close proximity to the atrioventricular node and the high risk of compl...

We present a 16-year-old patient with Wolff-Parkinson-White syndrome admitted with syncope and aborted sudden cardiac death. Electrocardiography showed only a short PR interval without a delta wave. The QRS transition zone was on V2 in the precordial leads. Twenty-four-hour ambulatory cardiac rhythm monitoring showed an obvious delta wave only at night-time. Electrophysiologic testing was perfo...

A 15-year-old boy with Wolff-Parkinson-White syndrome underwent an electrophysiology study for symptoms of palpitations and persistence of pre-excitation during peak exercise. He was detected to have right antero-septal accessory pathway with relatively long effective refractory period and no inducible tachycardia. He had only transient normalization with cryoablation. Eight months later, he pr...
