Concealed left superior accessory pathway. Distinctive features of retrograde atrial activation and successful ablation using transseptal approach

Europace. 2010 Apr;12(4):584-6. doi: 10.1093/europace/eup386. Epub 2009 Dec 4.

Abstract

Concealed left superior accessory pathways are very infrequent and can be difficult to diagnose and ablate. We describe here the case of a patient presenting with reciprocating tachycardia involving superior and inferior left accessory pathways. Left superior accessory pathway was suspected because of the simultaneous retrograde atrial activation at the distal coronary sinus (CS) and His bundle lead and could be successfully ablated using transseptal catheterization.
